The Efficacy of Herbal Supplement Danggui Buxue Tang for Relieving Menopausal Symptoms. J Menopausal Med 2022; 28:33-39. [PMID: 35534429 PMCID: PMC9086341 DOI: 10.6118/jmm.21024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 01/05/2022] [Accepted: 01/26/2022] [Indexed: 11/13/2022] Open
Abstract
Objectives This study aimed to further explore the efficacy and safety of Danggui Buxue Tang (DBT), a simple herbal formula, for improving the quality of life of women suffering from menopausal symptoms. Methods A third clinical trial to determine the clinical efficacy of high-dose DBT for a period of 12 weeks was carried out. The standard Menopause-Specific Quality of Life (MENQOL) assessment chart was used for the evaluation. Safety was defined as an absence of direct estrogenic effects, serum inflammatory cytokines. Notably, interleukin IL-6, IL-8 and tumor necrosis factor TNF-α, known to be directly related to estrogenic reactions in menopause studies, were monitored. Results The third clinical trial indicated an overall improvement in the four domains of MENQOL, offering further proof of the efficacy of DBT demonstrated in the two previous trials. The serial checks of the three cytokines related to estrogen activities did not show either upward or downward trends. The haphazard behavior reactions of the three cytokines offered indirect indications that DBT improved the MENQOL independently from estrogen activities. Conclusions The three clinical trials using DBT to relieve menopausal syndrome have offered solid evidence for its efficacy. The uncertainty regarding whether the “phytoestrogen” contained in DBT had bioactivities similar to estrogen was alleviated through the confirmation that no strict estrogenic bioactivities were observed. The issue of safety was further clarified via laboratory platform studies on DBT, which not only showed the lack of similarity with estrogen actions but also confirmed the value of combining the two herbs in the classic formula.

Tumorigenic risk of Angelica sinensis on ER-positive breast cancer growth through ER-induced stemness in vitro and in vivo. JOURNAL OF ETHNOPHARMACOLOGY 2021; 280:114415. [PMID: 34271113 DOI: 10.1016/j.jep.2021.114415] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 06/28/2021] [Accepted: 07/11/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The root of Angelica sinensis is widely used in traditional Chinese Medicine for relieving gynecological discomforts among the women population. However, its hormone-like effects have raised great attention on whether it is appropriate to use in breast cancer (BC) patients. Hence, this study aimed to investigate the tumorigenic effect of aqueous root extract of Angelica sinensis (AS) on estrogen receptor (ER)-positive BC growth through ER-induced stemness in-vitro and in-vivo. MATERIALS AND METHODS The chemical composition of the AS was characterized by HPLC. Cell viability was detected by MTS assay. The in-vivo effect of AS was investigated by xenograft model, immunohistochemistry, histology, Western blot, and self-renewal ability assay. Target verification was used by shRNA construction and transfection. Mammosphere formation assay was performed by flow cytometry. RESULTS AS significantly promoted the proliferation of MCF-7 cells and inhibited the growth of MDA-MB-231 cells. AS significantly induced tumor growth (2.5 mg/kg) in xenograft models and however tamoxifen treatment significantly suppressed the AS-induced tumor growth. AS induced ERα expression in both in-vivo and in-vitro and promoted cancer stem cell activity in ER-positive BC. CONCLUSION AS shows the tumorigenic potential on ER-positive BC growth through ERα induced stemness, suggesting that the usage of AS is not recommended for BC in terms of safety measures.

Danggui Buxue Tang, a Chinese herbal decoction containing Astragali Radix and Angelicae Sinensis Radix, improves mitochrondial bioenergetics in osteoblast. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 88:153605. [PMID: 34107409 DOI: 10.1016/j.phymed.2021.153605] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 05/05/2021] [Accepted: 05/16/2021] [Indexed: 06/12/2023]
Abstract
Osteoporosis is the process of bone loss, particular after menopause, when the production of estrogen in women is decreaing. Bioenergetic function is one of the critical roles in bone remodeling. Danggui Buxue Tang (DBT) is an herbal mixture containing Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), and which is consumed for "Qi-invigorating", i.e., stimulating energy metabolism, as a traditional Chinese medicine (TCM). However, the role of DBT in metabolism of osteoblast has not been examined. Here, we employed a metabolic flux to examine the mitochondrial functions of cultured osteoblast in the presence of herbal extracts, including DBT, ASR, AR, AR + ASR (single mixing of two herbal extracts), as well as DBT∆cal (a DBT extract depeleting calycosin), to examine their roles in osteoblastic metabolism, e.g. glycolysis and energy kinetics. By revealing the rates of oxygen consumption and extracellular acidification of mitochrondia, the DBT-treated osteoblasts were markedly strengthened with increases of maximal respiration, spare capacity, glycolysis capacity and glycolysis reserve, in comparing to other herbal extracts. In addition, the bioenergetic metabolism was modulated by DBT via the signaling of cellular Ca2+ and reactive oxgen species (ROS). Furthermore, DBT affected the morphology of mitochondria, as well as mitochondrial dynamic. Here, we propose that DBT can be regarded as benefit herbal extract in improving osteoblastic metabolism for bone disorders via central energy metabolism and mitochondrial bioenergetics.

[PMID: 34185887 DOI: 10.1111/and.14165] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 05/29/2021] [Accepted: 06/05/2021] [Indexed: 12/24/2022] Open
Abstract
The present study aimed to investigate the molecular mechanism of the Astragalus-Scorpion drug pair in the treatment of prostate cancer (PCa). We employed network pharmacology and molecular docking technology to retrieving the active ingredients and corresponding targets of Astragalus-Scorpion by using TCMSP, BATMAN-TCM, TCMID and Swiss Target Prediction Databases. The targets related to PCa were retrieved through GeneCards. Cytoscape software was used to construct the 'active ingredient-target disease' network, and GO and KEGG enrichment analyses were performed on the common targets. Autodock software was used for molecular docking verification. In total, 26 active ingredients, 340 potential targets related to active ingredients and 122 common targets were screened from Astragalus-Scorpion drug pair. The core targets of the protein-protein interaction (PPI) network were JUN, AKT1, IL6, MAPK1 and RELA, whereas the core active ingredients were quercetin, kaempferol, formononetin, 7-o-methylisomucronulatol and calycosin. Nearly 762 GO entries and 154 pathways were obtained by using the pathway enrichment analysis. Molecular docking results revealed that quercetin and kaempferol bind to AKT1 and formononetin binds to RELA, all of which were found to be stable bounds.

Integrated Omics Reveals the Orchestrating Role of Calycosin in Danggui Buxue Tang, a Herbal Formula Containing Angelicae Sinensis Radix and Astragali Radix, in Inducing Osteoblastic Differentiation and Proliferation. Front Pharmacol 2021; 12:670947. [PMID: 34248625 PMCID: PMC8260986 DOI: 10.3389/fphar.2021.670947] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 05/21/2021] [Indexed: 11/13/2022] Open
Abstract
Systems biology unravels the black box of signaling pathway of cells; but which has not been extensively applied to reveal the mechanistic synergy of a herbal formula. The therapeutic efficacies of a herbal formula having multi-target, multi-function and multi-pathway are the niches of traditional Chinese medicine (TCM). Here, we reported an integrated omics approach, coupled with the knockout of an active compound, to measure the regulation of cellular signaling, as to reveal the landscape in cultured rat osteoblasts having synergistic pharmacological efficacy of Danggui Buxue Tang (DBT), a Chinese herbal formula containing Angelicae Sinensis Radix and Astragali Radix. The changes in signaling pathways responsible for energy metabolism, RNA metabolism and protein metabolism showed distinct features between DBT and calycosin-depleted DBT. Here, our results show that calycosin within DBT can orchestrate the osteoblastic functions and signaling pathways of the entire herbal formula. This finding reveals the harmony of herbal medicine in pharmacological functions, as well as the design of drug/herbal medicine formulation. The integration of systems biology can provide novel and essential insights into the synergistic property of a herbal formula, which is a key in modernizing TCM.

Danggui Buxue Decoction enhances the anticancer activity of gemcitabine and alleviates gemcitabine-induced myelosuppression. JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113965. [PMID: 33639205 DOI: 10.1016/j.jep.2021.113965] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Revised: 02/20/2021] [Accepted: 02/22/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Danggui Buxue Decoction (DBD) as a traditional Chinese medicine (TCM) has been widely used to treat blood deficiency. With the immune regulation and hematopoietic effect, DBD improved the quality of life in non-small-cell lung cancer (NSCLC) patients. We previously reported that DBD sensitized the response of NSCLC to Gemcitabine (Gem); however, the synergism and attenuation mechanism on the combination of Gem and DBD has not yet been elucidated. AIM OF THE STUDY To investigate the mechanisms of DBD in enhancing the anticancer activity of Gem and alleviating Gem-induced myelosuppression. MATERIALS AND METHODS A549 nude mice model was established to study the effect on the combination of Gem and DBD. The organ indices, peripheral blood cells and the hematopoiesis-related cytokines were analyzed in Gem-induced myelosuppressive mice. Then we studied the whole process from Gem-induced bone marrow suppression to self-healing, and the mechanism of DBD's attenuation by the experiments of bone marrow nucleated cells (BMNCs). RESULTS There were an enhanced anticancer effect and an improvement of hematopoietic function by combining of Gem and DBD in A549 nude mice model. DBD regulated Hu antigen R (HuR), deoxycytidine kinase (dCK) and nuclear factor erythroid 2-related factor (Nrf2), increased the expression of thrombopoietin (TPO) and granulocyte-macrophage colony stimulating factor (GM-CSF). For Gem-induced myelosuppressive mice, DBD improved the number of peripheral blood cells and the levels of hematopoiesis-related cytokines. Moreover, DBD was observed to reduce deoxyribonucleic acid (DNA) content at the G1 phase, promoted BMNCs proliferation and up-regulated cycle-related proteins. CONCLUSIONS The results indicated that DBD not only improved the sensitivity of Gem but also alleviated Gem-induced myelosuppression. This study may provide a pharmacological basis for the combination of DBD and Gem in clinical application.

Integrating multiple-chromatographic approaches to evaluate chemical consistency of Chang-Kang-Fang preparations from mixed-herb decoction and combined single-herb decoction. J Pharm Biomed Anal 2021; 203:114186. [PMID: 34118572 DOI: 10.1016/j.jpba.2021.114186] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 05/26/2021] [Accepted: 05/31/2021] [Indexed: 12/08/2022]
Abstract
Chang-Kang-Fang formula (CKF), a multi-herbs traditional Chinese medicine (TCM) prescription for treating irritable bowel syndrome (IBS), has been clinically applied in the traditional form of mixed-herb decoction (MHD), or in the modern form of combined single-herb decoction (cSHD, so called dispensing granule decoction) in the near decades, but the chemical consistency between the MHD and cSHD is still unknown. Herein, a new strategy by integrating multiple-chromatographic approaches to characterize both polysaccharides and small molecules was developed to compare the chemical consistency between MHD and cSHD. Sixteen small molecules were simultaneously qualified and quantified by UPLC-QTOF-MS/MS, the molecular weight distribution of polysaccharides was characterized by HPGPC-ELSD, while the monosaccharide composition and total saccharides content were determined by HPLC-PDA and UV-VIS, respectively. It was found that the molecular weight range and monosaccharide composition of polysaccharides, as well as the composition of small molecules, were identical between MHD and cSHD. However, the contents of berberine, epiberberine, coptisine, palmatine, albiflorin and paeoniflorin in MHD were significantly lower than those in cSHD, whereas the content of polysaccharides in MHD was higher than that in cSHD, indicating that there is a significant difference in the quality between MHD and cSHD, in particular for the relative contents of major small molecules and polysaccharides. Whether or not these quality variations affect the efficacy and safety of CKF deserves further investigation.

Abstract
Objective To establish a HPLC fingerprints evaluation method for Angelica Sinensis Radix (ASR) based on traditional decoction process of Ancient Classical Prescriptions of Traditional Chinese Medicine (ACPTCM). Methods The fingerprints of 10 batches of ASR were further evaluated by chemometrics methods. The similarity analyzed with "Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine 2004A," and hierarchical clustering analysis (HCA) and principal component analysis (PCA) were performed by SPSS (version 22.0, SPSS Inc., Chicago, IL, USA). Results There were 12 common peaks, and the similarity degrees of 10 batches of samples were more than 0.923 and showed that all the samples from different origins were of good consistency. The samples were divided into 4 clusters by HCA. The results of PCA showed that the 3 factors were chosen, the quality of samples could be evaluated basically. The comprehensive score results show that the ASR with Lot.Nos.DG-18007, DG-18008 in Weiyuan County, Gansu and DG-18009 produced in Minle County, Gansu Province rank among the top 3 in all samples. Conclusions These results demonstrated that the combination of HPLC chromatographic fingerprint and chemometrics offers an efficient and reliable approach for quality evaluation of ASR from different sources as Ancient Classical Prescriptions ingredients.

Fermentation of Danggui Buxue Tang, an ancient Chinese herbal mixture, together with Lactobacillus plantarum enhances the anti-diabetic functions of herbal product. Chin Med 2020; 15:98. [PMID: 32944064 PMCID: PMC7488747 DOI: 10.1186/s13020-020-00379-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 09/05/2020] [Indexed: 12/19/2022] Open
Abstract
Background Danggui Buxue Tang (DBT), an ancient Chinese herbal decoction containing Astragali Radix and Angelicae Sinensis Radix at a ratio of 5: 1, is prescribed for menopausal women. Flavonoids and its flavonoid glycosides are considered as the major active ingredients within the herbal decoction; however, their amount is not controllable during the preparation. Besides, the aglycons within DBT are believed to have better gut absorption and pharmacological efficacy. Methods The herbal extract of DBT was fermented with Lactobacillus plantarum. The amounts of flavonoid glucosides and its aglycones in the fermented product were analyzed by using UPLC-MS/MS. In addition, in vitro assays were employed to evaluate the efficacy of the fermented DBT in regulating the activities of α-glucosidase, α-amylase and lipase, as well as their antioxidant capacity (DPPH and T-AOC assays) and anti-glycation property (BSA-methylglyoxal, BSA-fructose, and arginine-methylglyoxal models). Results The fermentation of DBT with L. plantarum drove a completed conversion of calycosin-7-O-β-D-glucoside and ononin to calycosin and formononetin, respectively. The chemical transformation could be probably mediated by β-glycosidase within the fermented product. Several in vitro assays corresponding to anti-diabetic functions were compared between parental DBT against its fermented product, which included the activities against α-glucosidase, α-amylase and lipase, as well as anti-oxidation and anti-glycation. The fermented DBT showed increased activities in inhibiting α-glycosidase, suppressing DPPH radical-scavenging and anti-glycation, as compared to the original herbal product. Conclusion These results suggested that DBT being fermented with the probiotic L. plantarum could pave a new direction for fermentation of herbal extract, as to strengthen its pharmacological properties in providing health benefits.

Abstract
BACKGROUND Traditional Chinese medicine (TCM) has been widely accepted and applied worldwide, and many publications related to Angelica sinensis (Oliv.) Diels (AS, Chinese name is "Danggui") have been published. However, to date, there has not been a scientometric study to systematically analyze the intellectual landscape and emerging research trends regarding AS. Therefore, we performed a scientometric study to address this gap. METHODS Publications related to AS published from 2009 to 2018 were identified and selected from the Web of Science (WoS) Core Collection on May 30, 2019 using relevant keywords. HistCite, CiteSpace, and Excel 2016 software tools were used to conduct this scientometric study. RESULTS Seven hundred and sixty-seven articles (including 717 primary articles and 60 review articles) and their cited references were included and analyzed. The majority of publications (N = 565, 73.7%) were published in mainland China, with Nanjing University of Chinese Medicine contributing the most publications (N = 42, 5.5%). The first core journal was Journal of Ethnopharmacology (N = 58, 7.6%; impact factor = 3.414). The identification and assessment of active components (like ferulic acid) of AS and their pharmacological actions (such as immunomodulatory effects) are the current research foci for AS research. CONCLUSION The present scientometric study provides an overview of the development of AS research over the previous decade using quantitative and qualitative methods, and this overview can provide references for researchers focusing on AS.

Abstract
Angelica sinensis (AS, Danggui) has long been regarded to stimulate breast cancer growth; hence, the use of AS in breast cancer patients remains a major concern for both patients and practitioners. Since safety studies of herbs would be unethical to carry out in patients, the present study aimed to investigate the potential unsafe effects of AS in a systematic pre-clinical approach. Human breast cancer cells, breast orthotopic tumor-bearing mouse models, as well as primary breast cancer cells from patients’ tumors were used to evaluate the effect of AS hot water extract on the progression of breast tumors and/or growth of breast cancer cells. We showed that AS is not that stimulatory in breast cancer both in vitro and in vivo, though AS should still be used with caution in estrogen receptor-positive breast cancer patients. This novel approach of applying breast cancer cell lines, xenograft, and syngeneic tumors models, as well as primary breast cancer cells from patients’ tumors in Chinese medicines safety evaluation was proven feasible. Our finding is important information for patients, Chinese medicine practitioners, and clinicians on the safety use of AS in breast cancer, which will affect future clinical practice.

Abstract
This study aimed to investigate whether the anti-tumor effect of gemcitabine (GEM) in non-small-cell lung cancer (NSCLC) treatment was affected by Danggui Buxue decoction (DBD), and explore the potential mechanisms. The combined use of GEM and DBD showed an enhanced tumor growth inhibition effect in a murine Lewis lung carcinoma (LLC) model. LC-MS/MS results showed that the pharmacokinetic behaviors of a GEM active metabolite, gemcitabine triphosphate (dFdCTP), were found to be altered remarkably in the peripheral blood mononuclear cells (PBMC) of DBD co-administration rats. In addition, after co-administration of DBD with GEM, Western Blot and qPCR results confirmed that the expression of deoxycytidine kinase (dCK) in tumor tissues of LLC-bearing mice were markedly increased. DBD co-administration also reversed the upregulation of P-glycoprotein (P-gp) in tumor tissues induced by GEM. Moreover, DBD could notably up-regulate the IL-12p70 and GM-CSF expression in mice serum, suggesting potential immunomodulatory activities in tumor-bearing mice. Meanwhile, DBD inhibited the P-gp efflux activity in A549 cells. Therefore, the regulation of dCK and P-gp played important roles in the alternation of GEM pharmacokinetics and the enhancement of the anti-tumor effect of GEM. DBD being a potential dCK promoter could work as an adjuvant agent to boost the anticancer effect of GEM.

Abstract
BACKGROUND An increasing number of breast cancer patients in Asian countries has been found to consume dietary supplements including phytoestrogen-rich Chinese herbal medicines with an expectation to alleviate the side effects of conventional cancer therapies. PURPOSE The question of whether estrogenic Chinese herbal medicines are beneficial or detrimental to the health of breast cancer patients remains uncertain. STUDY DESIGN The present study aimed at establishing a systematic approach to look at the safety profiles of estrogenic Chinese herbal medicines (CHM). METHODS The effects of estrogenic CHM on the growth of human breast cancer cells as well as the progression of breast tumors in mice have been investigated. RESULTS Our results demonstrated that among 10 selected estrogenic CHM, the aqueous extracts of Cistanche deserticola (CD) and Dioscorea opposita (DO) at 0.4 to 1.6 mg/ml significantly stimulated cell viability in both estrogen receptor (ER)-positive (MDA-MB-361 and MCF-7) and ER-negative (SKBR3 and MDA-MB-231) breast cancer cells. However, results from animal studies showed that no significant difference was found on the size of mouse 4T1 breast tumors in CD- and DO-treated mice when compared with the control group, while the number of proliferative cells were found to be increased in DO-treated group. Besides, CD and DO treatments induced significant immunomodulatory effects on 4T1 tumor-bearing mice by increasing the production of cytokines IL-2 and IFN-γ and modulation of regulatory T-cells. Furthermore, CD and DO treatments did not stimulate, but in fact suppressed human triple-negative MDA-MB-231 breast xenografts growth in immunodeficiency mice. CONCLUSION The considerable concerns on the use of CD and DO in breast cancer patients could be relieved to some extents upon the findings of this pre-clinical study. The potential harmful effects of estrogenic Chinese herbal medicines on breast cancer growth should be verified in both cell-based and tumor-bearing mice models.

Bone Protective Effects of Danggui Buxue Tang Alone and in Combination With Tamoxifen or Raloxifene in vivo and in vitro. Front Pharmacol 2018; 9:779. [PMID: 30150931 PMCID: PMC6099153 DOI: 10.3389/fphar.2018.00779] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2018] [Accepted: 06/26/2018] [Indexed: 11/26/2022] Open
Abstract
Danggui Buxue Tang (DBT), a traditional Chinese Medicine decoction containing Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), is commonly prescribed for women in China as a remedy for menopausal symptoms. Previous study indicated that DBT stimulated cell growth and differentiation of human osteosarcoma MG-63 cells and exhibited estrogenic properties via estrogen receptors (ERs). The present study aimed to study the bone protective effects of DBT and its potential interactions with selective estrogen receptor modulators (SERMs, tamoxifen and raloxifene) in both in vivo and in vitro models as they act via similar ERs. Six-month-old Sprague-Dawley rats were randomly assigned to the following treatments for 12 weeks: (1) sham-operated control group with vehicle (sham), (2) ovariectomized group with vehicle (OVX), (3) OVX with 17β-estradiol (E2, 2.0 mg/kg day), (4) OVX with tamoxifen (Tamo, 1.0 mg/kg day), (5) OVX with raloxifene (Ralo, 3.0 mg/kg day), (6) OVX with DBT (DBT, 3.0 g/kg day), (7) OVX with DBT+Tamoxifen (DBT+Tamo), and (8) OVX with DBT+Raloxifene (DBT+Ralo). Effects of DBT and potential interactions between DBT and SERMs were also evaluated in MG-63 cells. DBT, tamoxifen, raloxifene, and their combinations significantly increased bone mineral density (BMD) and improved trabecular bone properties, including bone surface (BS), trabecular bone number (Tb.N), and trabecular bone separation (Tb.Sp), as well as restored changes in bone turnover biomarkers and mRNA expression of genes involved in bone metabolism in OVX rats. Furthermore, DBT, SERMs, and their combinations significantly increased serum estradiol and suppressed follicle stimulating hormone and luteinizing hormone in OVX rats, suggesting the possible involvement of the hypothalamus–pituitary–gonadal axis in mediating their bone protective effects. However, SERMs, but not DBT, significantly increased uterus index in OVX rats. DBT significantly induced ALP activity and estrogen response element-dependent transcription in MG-63 cells. Our study demonstrated that DBT alone and in combinations with SERMs could exert bone protective effects in vitro and in vivo.

Danggui Buxue Tang, a simple Chinese formula containing Astragali Radix and Angelicae Sinensis Radix, stimulates the expressions of neurotrophic factors in cultured SH-SY5Y cells. Chin Med 2017; 12:24. [PMID: 28852418 PMCID: PMC5568261 DOI: 10.1186/s13020-017-0144-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2017] [Accepted: 08/12/2017] [Indexed: 01/25/2023] Open
Abstract
Background Danggui Buxue Tang (DBT), a phytoestrogen-enriched Chinese herbal formula, serves as dietary supplement in stimulating the “Blood” functions of menopausal women. In traditional Chinese medicine (TCM) theory, “Blood” has a strong relationship with brain activities. Previous studies supported that some ingredients of DBT possessed neuronal beneficial functions. Therefore, the neurotrophic function and the mechanistic action of DBT were systematically evaluated in cultured human neuroblastoma SH-SY5Y cells. Methods The DBT-triggered protein expressions were analyzed by western blotting, while the transcriptional activities of promoters coding for related genes were revealed by luciferase assays. For mechanistic analysis of DBT, Erk1/2 and its inhibitor U0126 were analyzed. Results The application of DBT in cultured neuroblastoma cells showed the efficacies in: (1) up-regulation of nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF); (2) activation of transcriptional activities of promoters coding for NGF, BDNF, GDNF; (3) activation of Erk1/2 and CREB; and (4) attenuation of the neurotrophic factor expression by the treatment of an Erk1/2 inhibitor. Conclusions Our study supports that MAPK/Erk pathway acts as fundamental role in monitoring DBT-induced expression of neurotrophic factors in cultured human neuroblastoma cell. These results shed light in developing the working mechanism of this ancient herbal decoction for its neuronal function.

Traditional Chinese medicine Danggui Buxue Tang inhibits colorectal cancer growth through induction of autophagic cell death. Oncotarget 2017; 8:88563-88574. [PMID: 29179457 PMCID: PMC5687627 DOI: 10.18632/oncotarget.19902] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2017] [Accepted: 07/12/2017] [Indexed: 12/14/2022] Open
Abstract
Purpose The induction of autophagic cell death is an important process in the development of anticancer therapeutics. We aimed to evaluate the activity of the ancient Chinese decoction Danggui Buxue Tang (DBT) against colorectal cancer (CRC) and the associated autophagy-related mechanism. Materials and methods CT26 CRC cells were implanted into syngeneic BALB/c mice for the tumor growth assay. DBT extracts and DBT-PD (polysaccharide-depleted) fractions were orally administered. The toxicity profiles of the extracts were analyzed using measurements of body weight, hemogram, and biochemical parameters. The morphology of tissue sections was observed using light and transmission electron microscopy. Western blotting and small interference RNA assays were used to determine the mechanism. Results DBT-PD and DBT, which contained an equal amount of DBT-PD, inhibited CT26 syngeneic tumor growth. In the tumor specimen, the expression of microtubule-associated proteins 1A/1B light chain 3B (LC3B) was upregulated by DBT-PD and DBT. The development of autophagosomes was observed via transmission electron microscopy in tumors treated with DBT-PD and DBT. In vitro experiments for mechanism clarification demonstrated that DBT-PD could induce autophagic death in CT26 cells accompanied by LC3B lipidation, downregulation of phospho-p70s6k, and upregulation of Atg7. RNA interference of Atg7, but not Atg5, partially reversed the effect of DBT-PD on LC3B lipidation and expression of phospho-p70s6k and Atg7. The changes in ultrastructural morphology and LC3B expression induced by DBT-PD were also partially blocked by the knockdown of Atg7 mRNA. Conclusion DBT induced autophagic death of colorectal cancer cells through the upregulation of Atg7 and modulation of the mTOR/p70s6k signaling pathway.

Effects of Dangguibuxue decoction on rat glomerular mesangial cells cultured under high glucose conditions. Altern Ther Health Med 2017; 17:283. [PMID: 28545434 PMCID: PMC5445487 DOI: 10.1186/s12906-017-1774-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2016] [Accepted: 05/08/2017] [Indexed: 12/13/2022]
Abstract
Background Dysfunction of glomerular mesangial cells (GMCs) plays an important role in pathogenesis of diabetic nephropathy. Here, we investigated the effects of Dangguibuxue decoction (DBD), an herbal traditional Chinese medicinal (TCM) formula composed of Astragali Radix and Angelicae Sinensis Radix, on GMC proliferation and fibrogenesis under high-glucose (HG) conditions. Methods Sixty male Sprague Dawley rats were divided into 5 groups and administered intragastric 0.9% saline, low concentration DBD (DBD-L, 1.75 g/kg/d), middle concentration DBD (DBD-M, 3.5 g/kg/d), high concentration DBD (DBD-H, 7.0 g/kg/d) and gliclazide (GL, 2 mg/kg/d), respectively, for 1 week, and then their sera were obtained. Rat mesangial cells (HBZY-1 cells) were treated with these sera under HG condition (30 mmol/L). Results The proliferation of GMCs under HG conditions was significantly greater than that under normal glucose condition. Low concentration DBD (DBD-L) inhibited proliferation of GMCs after 72-h incubation (P < 0.01), while high concentration DBD (DBD-H) inhibited GMCs proliferation at 24, 48 and 72 time points (P < 0.01). There was no significant difference between the inhibitory effect of DBD-H and GL sera on GMC proliferation (P > 0.05). Furthermore, all concentrations of DBD (DBD-L, DBD-M and DBD-H) significantly decreased the protein expression of α-SMA(α-smooth muscle actin) (P < 0.01), an indicator of interstitial fibrosis of GMCs. Finally, DBD-L, DBD-M, DBD-H sera obviously inhibited the increase of HYP (hydroxyproline)secretion under HG condition (P < 0.01). Conclusion Our results demonstrate an inhibitory effect of DBD extract on proliferation and fibrogenesis of GMCs under HG conditions. The potential role of DBD in the treatment of diabetic neuropathy merits further investigation.

Danggui Buxue Tang (Astragali Radix and Angelicae Sinensis Radix) for menopausal symptoms: A review. JOURNAL OF ETHNOPHARMACOLOGY 2017; 199:205-210. [PMID: 28163116 DOI: 10.1016/j.jep.2017.01.044] [Citation(s) in RCA: 46] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Revised: 01/21/2017] [Accepted: 01/21/2017] [Indexed: 06/06/2023]
Abstract
BACKGROUND Traditional Chinese medicine (TCM) has contributed greatly to human health in past several thousand years. Today, the development of TCM is facing two obstacles: (i) quality control of herbal extract; and (ii) action mechanisms not known. OBJECTIVES Among thousands of complex TCM formulations, Danggui Buxue Tang (DBT) is the simplest one. DBT is used to treat ailments in women and contains only two herbs, Astragali Radix (Huangqi; AR) and Angelicae Sinensis Radix (Danggui; ASR). The weight ratio of AR to ASR in DBT must be 5:1, as stipulated in AD 1247. By using DBT as a model formula, we develop a strategy to reveal the complexity of a traditional TCM formula. RESULTS There are 3 levels of research directions: (i) the preparation of DBT and its rationale behind; (ii) the traditional theory of DBT is elucidated by chemical and biological determinations; and (iii) the action mechanisms of DBT are revealed. CONCLUSION Through the chemical, biological, genomic and proteomic studies, a possible direction in resolving the preparation mythologies, pharmacological and mechanistic analyses of a TCM decoction is being proposed here.

The Traditional Chinese Medicine DangguiBuxue Tang Sensitizes Colorectal Cancer Cells to Chemoradiotherapy. Molecules 2016; 21:molecules21121677. [PMID: 27929437 PMCID: PMC6273051 DOI: 10.3390/molecules21121677] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2016] [Revised: 11/23/2016] [Accepted: 11/30/2016] [Indexed: 12/19/2022] Open
Abstract
Chemotherapy is an important treatment modality for colon cancer, and concurrent chemoradiation therapy (CCRT) is the preferred treatment route for patients with stage II and III rectal cancer. We examined whether DangguiBuxue Tang (DBT), a traditional Chinese herbal extract, sensitizes colorectal cancer cells to anticancer treatments. The polysaccharide-depleted fraction of DBT (DBT-PD) contains greater amounts of astragaloside IV (312.626 µg/g) and ferulic acid (1.404 µg/g) than does the original formula. Treatment of the murine colon carcinoma cell line (CT26) with DBT-PD inhibits growth, whereas treatment with comparable amounts of purified astragaloside IV and ferulic acid showed no significant effect. Concurrent treatment with DBT-PD increases the growth inhibitory effect of 5-fluorouracil up to 4.39-fold. DBT-PD enhances the effect of radiation therapy (RT) with a sensitizer enhancement ratio (SER) of up to 1.3. It also increases the therapeutic effect of CCRT on CT26 cells. Cells treated with DBP-PD showed ultrastructural changes characteristic of autophagy, including multiple cytoplasmic vacuoles with double-layered membranes, vacuoles containing remnants of degraded organelles, marked swelling and vacuolization of mitochondria, and autolysosome-like vacuoles. We conclude that DBT-PD induces autophagy-associated cell death in CT26 cells, and may have potential as a chemotherapy or radiotherapy sensitizer in colorectal cancer treatment.

Evaluation of safety of modified-Danggui Buxue Tang in rodents:immunological, toxicity and hormonal aspects. JOURNAL OF ETHNOPHARMACOLOGY 2016; 183:59-70. [PMID: 26732632 DOI: 10.1016/j.jep.2015.12.049] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/11/2015] [Revised: 12/23/2015] [Accepted: 12/24/2015] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Astragali (RA), Radix Angelicae Sinensis (RAS) and Folium Epimedii (FE) are three of the extensively applied herbs among traditional Chinese medicines for gynecological disorders and osteoporosis. A derivative herbal formula-RRF, consisting of the three medicines with a weight ratio of 5:1:5, is derived from a famous Chinese herbal formula-Danggui Buxue Tang (DBT). RRF has shown noteworthy perimenopause ameliorating effect in both ovariectomized rats and natural aging female rats, which might represent a promising candidate for the treatment of perimenopausal disorders. The aim of this study was to evaluate its immunological potential, chronic toxicity and reproductive effects by 26-week repeated daily administration in female rats, in order to optimize its safe use. MATERIALS AND METHODS The effect of RRF on immunological function was studied by macrophage phagocytosis, immune organ index, serum immunoglobulin level as well as delayed type hypersensitivity (DTH) in mice. For toxicity assessment, acute toxicity study was performed according to fixed dose procedure with a single oral administration of RRF to mice. In the oral chronic toxicity, 120 female rats were administrated RRF orally in 0, 1100, 4400, or 8800mg/kg/day doses for 26 weeks. Clinical signs, mortality, body weights, feed consumption, haemato-biochemical parameters, organ weights, histopathology and reproductive hormone profiles were examined at the end of the 13- and 26-week dosing period, as well as after the 4-week recovery period. RESULTS Oral administration of RRF at three doses (282, 564 and 1128mg/kg) significantly increased the indices of phagocytosis K, as compared with prednisone acetate (PR) group (p<0.05 or 0.01). Exposure of RRF dose-dependently boosted circulating serum IgM level (all p<0.01) in response to CRBC in PR-induced mice. Furthermore, RRF treatment elicited a significant increment (all p<0.01) in DNFB-induced DTH response and the immune organ indices in a dose-dependent manner in mice, in parellel to DNFB-induced group. In the single dose acute toxicity and repeated dose 90-day chronic toxicity investigations, no toxic signs/mortality were observed. RRF treatment did not cause any toxicologically significant changes in clinical signs, food consumption, body weight, relative organ weight, hematological parameters, clinical chemistry, gross pathology and histopathology between treatment and control groups. No treatment related gross/histopathological lesions were observed and no target organ was identified. Long-term repeated administration of RRF exerted a significant promotion on serum level of steroid hormone estradiol, progesterone and testosterone release, along with decrease of circulating pituitary follicle stimulating hormone, luteinizing hormone, and prolactin levels in female rats. The No Observed Adverse Effect Level (NOAEL) of RRF was determined to be over 8800mg/kg/day for elderly female rats, a dose that was equivalent to 50 times of human dose. CONCLUSION The present investigation demonstrated that RRF possessed appreciable immunopotentiating activity and had a relatively wide margin of safety. Long-term treatment of RRF exhibited estrogenic properties, and retarded certain age-associated degenerations. RRF might have the potential for further development as a safe and effective alternative/complementary to conventional medication in relieving perimenopausal symptoms.

Herb pairs containing Angelicae Sinensis Radix (Danggui): A review of bio-active constituents and compatibility effects. JOURNAL OF ETHNOPHARMACOLOGY 2016; 181:158-71. [PMID: 26807913 DOI: 10.1016/j.jep.2016.01.033] [Citation(s) in RCA: 52] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2015] [Revised: 01/17/2016] [Accepted: 01/21/2016] [Indexed: 05/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herb compatibility is one of the most important characteristics of traditional Chinese medicine (TCM). Rather than being used singly, Chinese herbs are often used in formulae to obtain synergistic effects or to diminish possible adverse reactions. Herb pair, the most fundamental and simplest form of multi-herb formulae, is a centralized representative of herb compatibility. Danggui (Angelicae Sinensis Radix), a widely used Chinese medicine, is usually combined with another herb to treat women's diseases in the clinic. A series of herb pairs containing Danggui have gradually become a focus of modern research, and they exhibit encouraging prospects for development. MATERIALS AND METHODS A systematic search for studies related to herb pairs containing Danggui was performed via a library search (books, theses, reports, newspapers, magazines, and conference proceedings) and an electronic search (Web of Science, PubMed, and Google Scholar). These sources were scrutinized for information on Danggui herb pairs. RESULTS Based on a previous statistical analysis, a database containing 16,529 formulae of Danggui from the "Dictionary of Traditional Chinese Medicine Formulae" was reviewed. The results showed a high frequency of compatibility between Danggui and other 22 herbs. The most common ratio among these chosen herb pairs was 1:1, and a majority of the pairs were applied for the treatment of diseases in internal medicine. The present paper reviews ethnopharmacology and advances in variations of the bio-active components and compatibility effects of the herb pairs containing Danggui, especially Danggui-Huangqi, Danggui-Chuanxiong, and Danggui-Shaoyao, which are used at high frequency. It was also observed that there were fewer studies of Danggui-Fuzi, Danggui-Huanglian, Danggui-Gancao, Danggui-Fangfeng and Danggui-Ganjiang, although they have been recorded in classical books as commonly used herb pairs. Moreover, some herb pairs such as Danggui-Niuxi and Danggui-Chaihu have been used at high frequency according to the statistical analysis, however, they were not recognized as herb pairs in many relevant books. CONCLUSIONS Recently, several TCM researchers have become interested in investigating the bio-active constituents and compatibility effects of herb pairs. Thus, some methods for in-depth study of herb pairs are essential to be established. The in vitro or in vivo bio-active constituents of herb pairs may differ from those of the single herbs. Additionally, comparative methods should be applied to study not only the bio-active constituents but also the effects of herb pairs. Study of component compatibility may be considered when the bio-active constituents and effects of an herb pair have been definitively demonstrated. Overall, the goal of our basic study of herb pairs should be their clinical application and the development of new drugs.

Abstract
Danggui Buxue Tang (DBT) is a simple combination of Radix Astragali and Radix Angelica sinensis (5:1), with a variety pharmacological activities. In the present study, a single intravenous injection of 30 mg/kg streptozotocin and subsequent six weeks of high glucose diet in Sprague Dawley rats were used to induce diabetic nephropathy. Rats with diabetes mellitus showed increased levels of fasting blood glucose (FBG), blood urea nitrogen (BUN), serum creatinine (Scr), serum and urine β2-microglobulins (β2-MG), and type IV collagen (all P<0.05). DBT treatment significantly decreased the levels of FBG, BUN, Scr, serum and urine β2-MG, and type IV collagen. Furthermore, DBT treatment significantly and dose-dependently restored the ultrastructural injury, and reduced the expression of heparanase, compared with the vehicle (P<0.05). Therefore, DBT may be a novel therapeutic approach for the prevention and treatment of diabetic nephrology.

Abstract
Dangguibohyul-tang (DBT), herbal formula composed of Astragalus membranaceus (AM) and Angelica sinensis (AS) at a ratio of 5 : 1, has been used for the treatment of various skin diseases in traditional medicine. We investigated the effect of DBT on allergic and inflammatory skin reaction in atopic dermatitis-like model compared to the single extract of AM or AS. DBT treatment showed the remission of clinical symptoms, including decreased skin thickness and scratching behavior, the total serum IgE level, and the number of mast cells compared to DNCB group as well as the single extract of AM- or AS-treated group. Levels of cytokines (IL-4, IL-6, IFN-γ, TNF-α, and IL-1β) and inflammatory mediators (NF-κB, phospho-IκBα, and phospho-MAPKs) were significantly decreased in AM, AS, and DBT groups. These results demonstrated that AM, AS, and DBT may have the therapeutic property on atopic dermatitis by inhibition of allergic and inflammatory mediators and DBT formula; a mixed extract of AM and AS based on the herb pairs theory especially might be more effective on antiallergic reaction as compared with the single extract of AM or AS.

Abstract
AIM The aim of this work was to establish a specific and sensitive method to comprehensively investigate and compare chemical constituents of Fuzi-Gancao herb pair (FG), consisting of Aconitum carmichaelii Debeaux (Fuzi, Chinese) and Roast Radix Glycyrrhizae (Glycyrrhiza glabra L., Gancao, in Chinese) and Fuzi alone to explore the underlying interaction mechanism of FG. METHOD An ultra-fast liquid chromatography-ion trap/time-of-flight mass spectrometry (UFLC/MS-IT-TOF) method using diazepam as internal standard was developed for the identification and semi-quantitative analysis of the phytochemical constituents of Fuzi and FG. Chromatographic separation was achieved on a UFLC column using a gradient program with 40 mmol·L(-1) ammonium acetate and acetonitrile as the mobile phase. RESULTS Fifty-one of the sixty compounds, including forty-five C19-diterpenoid alkaloids and six C20-diterpenoid alkaloids were tentatively identified in the extracts of Fuzi and FG through accurate mass measurements and fragmentation patterns. Comparing the contents of these alkaloids in these two extracts, it was found that the diester-diterpenoid alkaloids (DDAs) and the alkylolamine-diterpenoid alkaloids (ADAs) were increased, while the monoester-diterpenoid alkaloids (MDAs) were decreased in the extracts of FG. CONCLUSION This work provided comprehensive information for the quality control of Fuzi preparations, and the further investigation on the compatibility mechanisms of FG.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kai-Xin-San (KXS), a well-known traditional Chinese herbal decoction, has been widely used to treat mental depression and memory loss in China. It has a combination of four herbs: Ginseng Radix et Rhizoma (GR; root and rhizome of Panax ginseng C. A. Mey.), Polygalae Radix (PR; root of Polygala tenuifolia Wild.), Acori Tatarinowii Rhizoma (ATR; rhizome of Acorus tatarinowii Schott), and Poria (PO; sclerotium of Poriacocos (Schw.) Wolf), from which a pairing of two herbs was considered as paired-herb, such as the pairing of GR-PR and ATR-PO. The depression-induced neural cell loss is one of the major pathogenesis in depression. Here, an optimized KXS by changing the ratio of paired-herbs in KXS was demonstrated aiming at promoting neural cell differentiation. MATERIALS AND METHODS Quantitative assessment of chemical markers in each herbal extract was determined by LC-MS. Promoters of neurofilaments, NF68 and NF200, linked with luciferase reporter gene (pNF68-Luc and pNF200-Luc) were applied in cultured pheochromocytoma (PC12) cells to study the transcriptional activation of each herbal extract. The effect of GR-PR and ATR-PO in improving NF promoter activity was analyzed by Compusyn software. The activation of PKA was indicated. RESULTS In PC12 cells, an optimized KXS named KXS1:5 having 1:5 of GR-PR:ATR-PO had greater capability in promoting the expression of neurofilament. The synergistic effect of GR-PR and ATR-PO on the improved efficiency was further determined. Moreover, the treatment of H89, a PKA inhibitor, significantly inhibited the induced NF promoter activity. CONCLUSION These results indicated an optimized KXS by optimizing the compatibility of paired-herb and this compatibility was proven to exert synergistic effect. Moreover, the underlying mechanism was mediated by a PKA signaling pathway.

Functions of Danggui Buxue Tang, a Chinese Herbal Decoction Containing Astragali Radix and Angelicae Sinensis Radix, in Uterus and Liver are Both Estrogen Receptor-Dependent and -Independent. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:438531.

Abstract
Danggui Buxue Tang (DBT), a herbal decoction containing Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), has been used in treating menopausal irregularity in women for more than 800 years in China. Pharmacological results showed that DBT exhibited significant estrogenic properties in vitro, which therefore suggested that DBT could activate the nuclear estrogen receptors. Here, we assessed the estrogenic properties of DBT in an ovariectomized in vivo rat model: DBT was applied to the ovariectomized rats for 3 days. The application of DBT did not alter the weight of uterus and liver, as well as the transcript expression of the proliferation markers including the estrogen receptors α and β. However, DBT stimulated the transcript expression of the estrogen responsive genes. In addition, the inductive role of DBT on the expression of members of the aryl hydrocarbon receptor family in uterus and liver of ovariectomized rats was confirmed. These responses of DBT however were clearly distinct from the response pattern detectable here for 17β-estradiol. Therefore, DBT exhibited weak, but significant, estrogenic properties in vivo; however, some of its activities were independent of the estrogen receptor. Thus, DBT could be an exciting Chinese herbal decoction for an alternative treatment of hormone replacement therapy for women in menopause without subsequent estrogenic side effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Danggui Buxue Tang (DBT), a Chinese herbal decoction commonly used in treating women׳s ailments, contains two herbs: Angelica Sinensis Radix (ASR) and Astragali Radix (AR). Traditionally, ASR had to be pre-treated with yellow wine before the herbal preparation, which reduced the amount of volatile oil in water extract of ASR and DBT, and meanwhile the volatile oil-reduced DBT processed better bioactivities in cell cultures. The present study aimed to investigate the effect of volatile oil from ASR (Angelica oil) on the solubility of AR-derived ingredients and the biological properties of DBT. MATERIALS AND METHODS To standardize Angelica oil, four marker chemicals in ASR were determined by GC-QQQ-MS/MS. Subsequently, fifteen gram of AR was boiled with different amounts of Angelica oil. The amounts of astragaloside IV, calycosin, formononetin, total polysaccharides, total saponins and total flavonoids, all derived from AR, were extracted and determined by HPLC-UV/ELSD. To reveal the effect of Angelica oil on DBT functions, several cell assays related to the traditional functions of DBT were selected, including anti-platelet aggregation, induction of NO production, hematopoetic, estrogenic and osteogenic properties. RESULTS The inclusion of Angelica oil in AR during preparation significantly decreased the amount of AR-derived astragaloside IV, calycosin, formononetin, total saponins and total flavonoids in the final water extract. In parallel, an inclusion of Angelica oil caused a decrease of DBT׳s estrogenic and hematopoetic activities in cultured cells. Moreover, the Angelica oil decreased DBT-induced cell proliferation of cultured MG-63 and endothelial cells. CONCLUSIONS The results indicated that Angelica oil was a negative regulator for DBT chemically and biologically, which supported the traditional practice of preparing DBT by using the wine-treated ASR.

Chemical profile analysis and comparison of two versions of the classic TCM formula Danggui Buxue Tang by HPLC-DAD-ESI-IT-TOF-MSn. Molecules 2014; 19:5650-73. [PMID: 24786849 PMCID: PMC6270708 DOI: 10.3390/molecules19055650] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2014] [Revised: 04/10/2014] [Accepted: 04/19/2014] [Indexed: 01/02/2023] Open
Abstract
Danggui Buxue Tang (DBT) is a Traditional Chinese Medicine (TCM) formula primarily used to treat symptoms associated with menopause in women. Usually, DBT is composed of one portion of Radix Angelicae Sinensis (RAS) and five portions of Radix Astragali (RA). Clinically, Radix Hedysari (RH) is sometimes used by TCM physicians to replace RA in DBT. In order to verity whether the chemical constituents of the DBT1 (RA:RAS = 5:1, w/w) and DBT2 (RH:RAS = 5:1, w/w) share similarities the chemical profiles of the two DBTs crude extracts and urine samples were analyzed and compared with the aid of HPLC-DAD-ESI-IT-TOF-MSn, which determines the total ion chromatogram (TIC) and multi-stage mass spectra (MSn). Then, the DBT1 and DBT2 were identified and compared on the basis of the TIC and the MSn. In the first experiment (with crude extracts), 69 compounds (C1–C69) were identified from the DBT1; 46 compounds (c1–c46) were identified from the DBT2. In the second experiment(with urine samples), 44 compounds (M1–M44) were identified from the urine samples of rats that had been administered DBT1, and 34 compounds (m1–m34) were identified from the urine samples of rats that had been administered DBT2. Identification and comparison of the chemical compositions were carried out between the DBT1 and DBT2 of the crude extracts and urine samples respectively. Our results showed that the two crude extracts of the DBTs have quite different chemical profiles. The reasons for their differences were that the special astragalosides in DBT1 and the isoflavonoid glycosides formed the malonic acid esters undergo single esterification and acetyl esters undergo acetylation in DBT1. In contrast, the urine from DBT1-treated rats strongly resembled that of DBT2-treated rats. These metabolites originate mainly from formononetin, calycosin and their related glycosides, and they were formed mainly by the metabolic process of reduction, deglycosylation, demethylation, hydrogenation and sulfation. The HPLC-DAD-ESI-IT-TOF-MSn method was successfully applied for the rapid chemical profiles evaluation of two DBTs and their related urine samples.

JOURNAL OF ETHNOPHARMACOLOGY 2014; 153:169-177. [PMID: 24583239 DOI: 10.1016/j.jep.2014.02.004] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2013] [Revised: 01/09/2014] [Accepted: 02/07/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Blood deficiency is commonly encountered among women, and is the root of many gynecological disorders. Danggui Buxue Decoction (DBD), a classical traditional Chinese formula which is composed of Astragali Radix (AR) and Angelicae Sinensis Radix (ASR) at the ratio of 5:1 (w/w), is widely used in TCM clinics for treatment of blood deficiency syndrome. This study is to compare the in vivo pharmacokinetic properties of seven major bio-active components in normal and blood deficiency rats after oral administration of DBD. MATERIALS AND METHODS Blood deficiency rats were induced by bleeding from orbit at the dosages of 5.0mL/kg each day for 12 days. Normal and blood deficiency rats were administrated of DBD on the 12th day at the dosage of 20g/kg, and blood was collected at different time points after then. Concentrations of ferulic acid, caffeic acid, butylphthalide, ligustilide, calycosin-7-O-β-glucoside, ononin, and astragaloside IV in plasma were quantified by UPLC-TQ/MS, and the main pharmacokinetic parameters were calculated by DAS 2.0. RESULTS It was found that Cmax, Tmax and MRT0~T of astragaloside IV, Cmax, T1/2Z, AUC0~T and MRT0~T of calycosin-7-O-β-glucoside, T1/2Z and AUC0~T of ferulic acid, T1/2Z, AUC0~T and MRT0~T of ononin, and MRT0~T of ligustilide, butylphthalide, and caffeic acid in blood deficiency rats was significantly different (P<0.05) from normal rats. CONCLUSIONS This study was the first report about pharmacokinetic investigation in blood deficiency animals which was conducted by bleeding. And the results demonstrated that the seven DBD constituents in normal and blood deficiency rats had obvious differences in some pharmacokinetic characteristics, suggesting that the rate and extent of drug metabolism were altered in blood deficiency animals.

Hydrolysis of Glycosidic Flavonoids during the Preparation of Danggui Buxue Tang: An Outcome of Moderate Boiling of Chinese Herbal Mixture. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:608721. [PMID: 24744813 PMCID: PMC3976805 DOI: 10.1155/2014/608721] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2013] [Accepted: 02/07/2014] [Indexed: 11/18/2022]
Abstract
Chemical change during boiling of herbal mixture is a puzzle. By using Danggui Buxue Tang (DBT), a herbal decoction that contains Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), we developed a model in analyzing the hydrolysis of flavonoid glycosides during the boiling of herbal mixture in water. A proper preparation of DBT is of great benefit to the complete extraction of bioactive ingredients. Boiling of DBT in water increased the solubility of AR-derived astragaloside IV, calycosin, formononetin, calycosin-7-O-β-D-glucoside, and ononin in a time- and temperature-dependent manner: the amounts of these chemicals reached a peak at 2 h. The glycosidic resides of AR, calycosin-7-O-β-D-glucoside, and ononin could be hydrolyzed during the moderate boiling process to form calycosin and formononetin, respectively. The hydrolysis efficiency was strongly affected by pH, temperature, and amount of herbs. Interestingly, the preheated herbs were not able to show this hydrolytic activity. The current results supported the rationality of ancient preparation of DBT in boiling water by moderate heat.

Danggui to Angelica sinensis root: are potential benefits to European women lost in translation? A review. JOURNAL OF ETHNOPHARMACOLOGY 2014; 152:1-13. [PMID: 24365638 DOI: 10.1016/j.jep.2013.12.018] [Citation(s) in RCA: 59] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2013] [Revised: 11/25/2013] [Accepted: 12/15/2013] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Danggui (Chinese Angelica root; Dong quai; Angelica sinensis (Oliv.) Diels.) is a traditional Chinese herbal remedy with a long history of use in China, Korea and Japan. Even today it is still one of the herbs most commonly used by Traditional Chinese Medicine (TCM) practitioners in China, as well as Europe. It is mainly used for the treatment of women's reproductive problems, such as dysmenorrhea, amenorrhoea, menopause, among others. Using Angelica sinensis (Oliv.) Diels. root as the example, this Review examines the ease with which the use of a Traditional Chinese Herbal Remedy can be transposed from one culture to another. By examining the more recent literature, a number of aspects are considered by the author to be potentially lost in translation: (i) identity and quality (phytochemistry); (ii) tradition of use and processing (smoke-drying, stir-frying, with and without wine); (iii) method of use and traditional types of Chinese herbal medicines; (iv) ethnic differences (Caucasian vs. Asian); (v) efficacy, safety and potential for western drug-herb interactions. MATERIALS AND METHODS This review is based on evaluation of the literature available in scientific journals, textbooks, electronic sources such as ScienceDirect, PubMed, Scopus, etc., as well as other web-sites. RESULTS A vast amount of information concerning the use of Angelica sinensis exists in the public domain. Many aspects associated with the use of the root are deemed problematical, such as identity, processing, amount and types of constituents, tradition of use in combination with other Chinese herbs, ethnicity of users, etc. Numerous constituents have been isolated with phthalides, ferulic acid and polysaccharides showing biological activities. CONCLUSION In spite of the potential activities associated with the traditional use of danggui, and the many trials using the Chinese system of 'Zheng differentiation', well-designed western-style clinical trials carried out using the authenticated, chemically standardized crude drug material to confirm clinical efficacy are in short supply. However increasing research into Angelica sinensis extracts and constituents shows that many of the traditional uses are not without scientific basis.

Abstract
Traditional Chinese medicine (TCM) has been extensively applied as preferable herbal remedy for menopausal symptoms. In the present work, the potential of a TCM recipe named RRF, composed of Radix Astragali, Radix Angelicae Sinensis, and Folium Epimedii, was investigated on a natural aging rat model. After administration of RRF (141, 282, and 564 mg/kg/d), the circulated estradiol (E2) level increased accompanied by a reduction of serum follicle stimulating hormone (FSH). But no significant impact on serum lutenizing hormone (LH) level was observed. As a result of the E2-FSH-LH adjustment, the histomorphology degenerations of ovary, uterus, and vagina of the 11.5-month female rats were alleviated. And lumbar vertebrae trabecular microstructure was also restored under RRF exposure by means of increasing the trabecular area and area rate. Moreover, levels of hypothalamic dopamine (DA) and norepinephrine (NE) rallied significantly after RRF treatment. Results from our studies suggest that RRF possesses a positive regulation on the estrogen imbalance and neurotransmitter disorder, thereby restoring reproductive organ degeneration and skeleton deterioration. The above-mentioned benefits of RRF on the menopause syndromes recommend RRF as a potential candidate for the treatment of perimenopausal syndrome.

Yu Ping Feng San, an ancient Chinese herbal decoction containing Astragali Radix, Atractylodis Macrocephalae Rhizoma and Saposhnikoviae Radix, regulates the release of cytokines in murine macrophages. PLoS One 2013; 8:e78622.

Abstract
Yu Ping Feng San (YPFS), a Chinese herbal decoction, is composed of Astragali Radix (AR; Huangqi), Atractylodis Macrocephalae Rhizoma (AMR; Baizhu) and Saposhnikoviae Radix (SR; Fangfeng) in a weight ratio of 1∶2∶1. Clinically, YPFS has been widely used to regulate immune functions; however, the action mechanism of it is not known. Here, we addressed this issue by providing detail analyses of chemical and biological properties of YPFS. By using rapid resolution liquid chromatography coupled with mass spectrometry, fifteen chemicals deriving from different herbs of YPFS were determined, and which served as a control for the standardization of the herbal extract of YPFS. In general, the amounts of chosen chemical markers were higher in a preparation of YPFS as compared to that of single herb or two-herb compositions. In order to reveal the immune functions of YPFS, the standardized extract was applied onto cultured murine macrophages. The treatment of YPFS stimulated the mRNA and protein expressions of pro-inflammatory cytokines via activation of NF-κB by enhancing IκBα degradation. In contrast, the application of YPFS suppressed the expressions of pro-inflammatory cytokines significantly in the lipopolysaccharide (LPS)-induced chronic inflammation model. In addition, YPFS could up regulate the phagocytic activity in cultured macrophages. These results therefore supported the bi-directional immune-modulatory roles of YPFS in regulating the releases of cytokines from macrophages.

Abstract
Astragali Radix (AR) and Angelicae Sinensis Radix (ASR) were frequently combined and used in China as herbal pair called as Danggui Buxue Decoction (DBD) for treatment of blood deficiency syndrome, such as women's ailments. This study is to investigate the tissue distribution profiles of five major bio-active constituents (ferulic acid, caffeic acid, calycosin-7-O-β-glucoside, ononin and astragaloside IV) in DBD after oral administration of DBD in blood deficiency rats, and to compare the difference between normal and blood deficiency rats. The blood deficiency rats were induced by bleeding from orbit at the dosages of 5.0mLkg(-1) every day, and the experimental period was 12 days. At the finally day of experimental period, both normal and blood deficiency rats were orally administrated with DBD, and then the tissues samples were collected at different time points. Ferulic acid, caffeic acid, calycosin-7-O-β-glucoside, ononin and astragaloside IV in different tissues were detected simultaneously by UPLC-TQ/MS, and the histograms were drawn. The results showed that the overall trend was CLiver>CKidney>CHeart>CSpleen>CLung, CC-30min>CM-30min>CM-60min>CC-5min>CM-5min>CC-60min>CM-240min>CC-240min. The contents of the detected compounds in liver were more than that in other tissues no matter in normal or blood deficiency rats. Compared to normal rats, partial contents of the compounds in blood deficiency rats' tissues at different time points had significant difference (P<0.05). This study was the first report about tissue distribution investigation in blood deficiency animals which is conducted by bleeding. And the results demonstrated that the five DBD components in normal and blood deficiency rats had obvious differences in some organs and time points, suggesting that the blood flow and perfusion rate of the organ were altered in blood deficiency animals.

Abstract
Despite the classical hormonal effect, estrogen has been reported to mediate neuroprotection in the brain, which leads to the searching of estrogen-like substances for treating neurodegenerative diseases. Flavonoids, a group of natural compounds, are well known to possess estrogenic effects and used to substitute estrogen, that is, phytoestrogen. Flavonoid serves as one of the potential targets for the development of natural supplements and therapeutic drugs against different diseases. The neuroprotection activity of flavonoids was chosen for a possible development of anti-Alzheimer's drugs or food supplements. The estrogenic activity of two flavonoids, baicalein and daidzein, were demonstrated by their strong abilities in stimulating estrogen receptor phosphorylation and transcriptional activation of estrogen responsive element in MCF-7 breast cells. The neuroprotection effects of flavonoids against β-amyloid (Aβ) were revealed by their inhibition effects on in vitro Aβ aggregation and Aβ-induced cytotoxicity in PC12 neuronal cells. More importantly, the estrogenic and neuroprotective activities of individual flavonoid could be further enhanced by the cotreatment in the cultures. Taken together, this synergistic effect of baicalein and daidzein might serve as a method to improve the therapeutic efficacy of different flavonoids against Aβ, which might be crucial in developing those flavonoidsin treating Alzheimer's disease in the future.

Abstract
Roots of Angelica sinensis (Danggui) have been used in promoting blood circulation as herbal medicine for over 2000 years in China. Another species of Angelica roots called A. gigas is being used in Korea. To reveal the efficiency of different Angelica roots, the chemical and biological properties of Angelica roots from different cultivated regions were compared. Roots of A. sinensis contained higher levels of ferulic acid, Z-ligustilide, and senkyunolide A, while high amounts of butylphthalide and Z-butylenephthalide were found in A. gigas roots. The extracts deriving from A. gigas roots showed better effects in osteogenic and estrogenic properties than that of A. sinensis from China. However, this difference was markedly reduced when the Angelica roots were being prepared in a Chinese herbal decoction together with Astragali Radix as Danggui Buxue Tang. In contrast, the herbal decoction prepared from A. sinensis roots showed better responses in cell cultures. In addition, the extracts of A. gigas roots showed strong cell toxicity both as single herb and as Danggui Buxue Tang. This result revealed the distinct properties of Angelica roots from China and Korea suggesting the specific usage of herb in preparing a unique herbal decoction.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Astragali (root of Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, RA), Radix Angelicae sinensis (root of Angelica sinensis (Oliv.) Diels, RAS) and Folium Epimedii (leaves of Epimedium brevicomum Maxim., FE) are three of the extensively applied herbal remedies among traditional Chinese medicines for gynecological disorders and osteoporosis. A derivative herbal recipe-RRF, composed of the three medicines with a weight ratio of 5:1:5, is derived from a famous Chinese herbal formula-Danggui Buxue Tang (DBT). RRF has shown noteworthy protective effect in ovariectomized rats, which might represent a promising candidate for the treatment of perimenopausal disorders. The aim of this study was to investigate the herbal recipe RRF for its efficacy on perimenopausal disorders and the underlying mechanisms via ovariectomy (OVX) models. MATERIALS AND METHODS An experimental model of OVX female rats was applied. Vehicle (Sham and OVX group), RRF (564, 282 and 141 mg/kg/d) and conjugated equine estrogens (CEE, 0.1mg/kg/d, reference drug) were all administrated orally once daily for 16 weeks post operation. After the treatment, radioimmunoassay for estradiol (E(2)), lutenizing hormone (LH), follicle stimulating hormone (FSH) and β-endorphin (β--EP), neurotransmitter determination by high-performance liquid chromatography with electrochemical detector (HPLC-ECD) for norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-HT) and 5-HIAA (5-hydroxyindoleacetic acid), bone mineral density (BMD) assay as well as lipid peroxidation assessment, were carried out to probe into the effectiveness of RRF. RESULTS (1) RRF treatment enhanced E(2) synthese while diminished the elevated serum FSH and LH levels; in terms of neurotransmitter, β-EP syntheses rallied whereas the hypothalamic NE, DA and 5-HT release experienced varying mitigation in OVX female rats. (2) Repeated administration of RRF was able to attenuate osteoporosis by elevating the BMD levels of total body, and arrest the bone trabeculae degradation. (3) RRF exposure decreased serum levels of constituent MDA and increased endogenous SOD activity. CONCLUSIONS Results of the current studies revealed that RRF was capable of acting at multiple targets which presumably underlay its potential protective effect in OVX rats mimicking symptoms as observed in perimenopausal women. Hence, RRF might represent a promising candidate in the treatment of perimenopausal disorders in midlife women.

Abstract
BACKGROUND Nowadays, the individual differences are emphasized in personalized medicine. Traditional Chinese Medicine (TCM) which prescribes tailored treatment based on each patient's different body constitution may provide new strategy to break the bottleneck of modern medicine (MM). Therefore, to integrate TCM into MM, an objective, reliable and rigorous diagnostic tool is necessary for the assessment of TCM constitution of each individual. This study aimed to develop a provisional version of the Yin-Xu Constitution Questionnaire (BCQ-), because evaluating the level of individual's Yin deficiency (Yin-Xu) by his manifestations is frequently involved in TCM clinical trials. METHODS The provisional version of BCQ- was developed using a step-by-step approach: 1) to form the research team and select a panel of 26 experts who had both MM and TCM educational background and professional training for Delphi method; 2) to generate questionnaire items from literature review and Delphi process, refine these items to be colloquially acceptable, and evaluate their face and content validities by Delphi process again; 3) to evaluate the difficulty of answering these questions by a pilot study with 81 participants whose age ranged from 20 to 60 years. RESULTS After 2 rounds of Delphi process, 22 colloquially appropriate questions were established and answered without difficulty by the 81 participants. CONCLUSIONS This provisional version of BCQ- appeared to have considerable face and content validities and may be the basis to develop an advanced Yin-Xu questionnaire. The reliability and validity of BCQ- were further tested in the second part of the study.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Over the past decades, research of traditional Chinese medicine (TCM) mainly focused on developing potential candidates from Chinese medicinal herbs, while the wisdom of applying these traditional herbs has not been paid as much attention as it deserves. As is well-known, multi-herb therapy is one of the most important characteristics of TCM, but the modernization drive of this conventional wisdom has faced many obstacles due to its unimaginable complexity. Herb pairs, the most fundamental and the simplest form of multi-herb formulae, are a centralized representative of Chinese herbal compatibility. In light of their simplicity and the basic characteristics of complex formulae, herb pairs are of great importance in the studies of herb compatibility. MATERIALS AND METHODS A systematic search of herb pair related research was carried out using multiple online literature databases, books and monographs published in the past 20 years. RESULTS A comprehensive introduction to the compatibility of TCM, the position of herb pairs in TCM and the progresses of several famous herb pairs were provided in this review. Furthermore, the clinical study and the future research trends of herb pairs were also discussed. CONCLUSIONS Herb pairs have played, and may continue to play a key role in full investigation of general herb compatibility for their indispensable position in TCM. Much more research is needed for the standardization, safety evaluation, and mechanism exploration of herb pairs.

Er Zhi Wan, an ancient herbal decoction for woman menopausal syndrome, activates the estrogenic response in cultured MCF-7 cells: an evaluation of compatibility in defining the optimized preparation method. JOURNAL OF ETHNOPHARMACOLOGY 2012; 143:109-115. [PMID: 22710293 DOI: 10.1016/j.jep.2012.06.009] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/13/2012] [Revised: 05/29/2012] [Accepted: 06/06/2012] [Indexed: 06/01/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Er Zhi Wan (EZW), a Chinese medicinal preparation, has been used clinically for treating menopausal syndrome for its kidney-invigorating function, which contains simply two herbs, Ecliptae Herba (EH) and Ligustri Lucidi Fructus (LLF). Although this herbal extract has been used for many years, there is no scientific basis about its effectiveness on menopausal symptom. Here, we aimed to evaluate the estrogenic activities of EZW and to study the compatibilities of two herbs including different processed-LLF in single and mixed preparation of EZW. Moreover, the weight ratio of EH to LLF in EZW was determined according to their estrogenic activities. MATERIALS AND METHODS The extractions of LLF, processed-LLF and EH were prepared separately by extracting the powders with water, 50% alcohol or 95% alcohol. Steamed-LLF and EH were extracted separately, or together, in preparing EZW extracts. A promoter-reporter construct (pERE-Luc) containing three repeats of estrogen responsive elements (ERE) was stably transfected into MCF-7 cells, and this stable breast cancer cell line was used to determine the estrogenic property. The cell proliferation was measured by MTT assay. RESULTS The results showed that EZW could significantly induce the expression of luciferase driven by an estrogen responsive element in a pERE-Luc vector. The proliferation of MCF-7 cells was not altered by this herbal treatment. The best preparation of EZW was from: (i) LLF was firstly steamed over water and then dried to make steamed-LLF; and (ii) steamed-LLF and EH were extracted separately by 95% alcohol and then mixed together according to a weight ratio of 1:1. CONCLUSIONS Under the optimized extracting method, EZW possessed robust effect in activating the estrogenic activity, but which did not alter the proliferation of cultured MCF-7 cells. Thus, EZW is an effective and safe estrogenic herbal extract.

Chemical and biological assessment of Angelica herbal decoction: comparison of different preparations during historical applications. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2012; 19:1042-1048. [PMID: 22902230 DOI: 10.1016/j.phymed.2012.07.009] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2012] [Revised: 06/27/2012] [Accepted: 07/17/2012] [Indexed: 06/01/2023]
Abstract
The commonly used Angelica herbal decoction today is Danggui Buxue Tang (DBT), which is a dietary supplement in treating menopausal irregularity in women, i.e. to nourish "Qi" and to enrich "Blood". According to historical record, many herbal decoctions were also named DBT, but the most popular formulation of DBT was written in Jin dynasty (1247 AD) of China, which contained Astragali Radix (AR) and Angelicae Sinensis Radix (ASR) with a weight ratio of 5:1. However, at least two other Angelica herbal decoctions recorded as DBT were prescribed in Song (1155 AD) and Qing dynasties (1687 AD). Although AR and ASR are still the major components in the DBT herbal decoctions, they are slightly varied in the herb composition. In order to reveal the efficiency of different Angelica herbal decoctions, the chemical and biological properties of three DBT herbal extracts were compared. Significantly, the highest amounts of AR-derived astragaloside III, astragaloside IV, calycosin and formononetin and ASR-derived ferulic acid were found in DBT described in 1247 AD: this preparation showed stronger activities in osteogenic, estrogenic and erythropoetic effects than the other two DBT. The current results supported the difference of three DBT in chemical and biological properties, which could be a result of different herbal combinations. For the first time, this study supports the popularity of DBT described in 1247 AD.

The membrane permeability of Astragali Radix-derived formononetin and calycosin is increased by Angelicae Sinensis Radix in Caco-2 cells: a synergistic action of an ancient herbal decoction Danggui Buxue Tang. J Pharm Biomed Anal 2012; 70:671-9. [PMID: 22704738 DOI: 10.1016/j.jpba.2012.05.018] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2012] [Revised: 05/10/2012] [Accepted: 05/14/2012] [Indexed: 11/25/2022]
Abstract
Danggui Buxue Tang (DBT), a herbal decoction contains Astragali Radix (AR) and Angelicae Sinensis Radix (ASR), has been used as a health food supplement in treating menopausal irregularity in women for more than 800 years in China. Several lines of evidence indicate that the synergistic actions of AR and ASR in this herbal decoction leading to a better pharmacological effect of DBT. Here, the role of different herbs in directing the transport of active ingredients of DBT was determined. A validated RRLC-QQQ-MS/MS method was applied to determinate the permeability of ingredients across the Caco-2 cell monolayer. AR-derived chemicals, including astragaloside IV, calycosin and formononetin, as well as ASR-derived chemicals, including ferulic acid and ligustilide, were determined by RRLC-QQQ-MS/MS. The pharmacokinetic results showed that the membrane permeabilities of calycosin and formononetin, two of the major flavonoids in AR, could be markedly increased in the presence of ASR extract: this induction effect could be mediated by ferulic acid deriving from ASR. In contrast, the extract of AR showed no effect on the chemical permeability. The current results suggested that the ingredients of ASR (such as ferulic acid) could enhance the membrane permeability of AR-derived formononetin and calycosin in cultured Caco-2 cells. The possibility of herb-drug synergy within DBT was proposed here.

Danggui Buxue Tang attenuates eosinophil infiltration and airway hyperresponsiveness in asthmatic mice. Ann Allergy Asthma Immunol 2011; 107:501-9. [PMID: 22123379 DOI: 10.1016/j.anai.2011.08.006] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2011] [Revised: 07/24/2011] [Accepted: 08/16/2011] [Indexed: 12/16/2022]
Abstract
BACKGROUND Danggui Buxue Tang (DBT), an herbal formula containing Angelica sinensis (AS) and Astragalus membranaceus (AM) (AS:AM = 1:5, designated as DBT1 here), has been used in Chinese medicine to enhance qi and blood circulation. In addition, DBT has served as a treatment for atopic dermatitis in dogs in Taiwan. It also may improve fibrosis in a rat model of pulmonary fibrosis. OBJECTIVE In this study, we evaluated the effect of oral administration of DBT1 in asthma in ovalbumin (OVA)-sensitized mice. METHODS Female BALB/c mice were sensitized and challenged with OVA and fed with DBT1 or modified formulas of DBT1, designated as DBT2 (AS:AM = 1:1) and DBT3 (AS:AM = 5:1), from days 21 to 27. RESULTS DBT1 suppressed airway hyperresponsiveness and eosinophil infiltration in bronchoalveolar lavage fluid (BALF) and lung, and Th2-associated cytokines and chemokines were inhibited in BALF. In addition, levels of OVA-immunoglobulin E (IgE) also were suppressed in serum. However, treatment with DBT2 or DBT3 showed no improved effects relative to DBT1 in treating asthmatic symptoms. CONCLUSIONS These results suggest that orally administered DBT (DBT1) can reduce allergic reactions in OVA-sensitized mice.

Differential effects of anti-metastatic mechanism of Tian-Xian liquid (TXL) and its bioactive fractions on human colorectal cancer models. JOURNAL OF ETHNOPHARMACOLOGY 2011; 137:403-413. [PMID: 21669277 DOI: 10.1016/j.jep.2011.05.035] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2011] [Revised: 04/17/2011] [Accepted: 05/30/2011] [Indexed: 05/30/2023]
Abstract
AIM OF STUDY This study aimed to elucidate and compare the anti-metastatic mechanism of Tian-Xian liquid (TXL) and its bioactive components namely butanol (BU), ethyl-acetate (EA) and aqueous (WA) fractions on human colorectal cancer in vitro (HT-29 cancer cells) and in vivo (nude mouse xenografts). MATERIALS AND METHODS The anti-proliferative effects of TXL and its bioactive components in HT-29 cells were determined by MTT assay. Their modulations on the potential angiogenic and metastatic marker expressions on HT-29 cells and xenografts were investigated by real-time PCR and Western blot at transcriptional and translational levels, respectively. For the in vitro study, migration abilities of HT-29 cells were determined using wound healing assay. For the in vivo study, daily measurements of the tumor size and volume of the xenografts were also performed. RESULTS TXL, BU, EA and WA effectively inhibited the proliferation of HT-29 cells in a dose- and time-dependent manner. The IC(50) value of TXL on HT-29 cells was obtained after incubation with 1% (v/v) TXL for 4h; whereas IC(50) values were obtained for the following bioactive components: BU at 1.25% (v/v); EA at 5% (v/v); and WA at 0.3125% (v/v). It was found that 1% (v/v) TXL significantly down-regulated MMP2 and MMP7 expression at both transcriptional and translational levels and it reduced MMP9 and VEGF protein expression in vitro. TXL decreased the metastatic ability of HT-29 cells as demonstrated by wound healing assay. TXL and its bioactive fractions caused no significant changes in the body weight indicating lack of toxicity to the xenografts. CONCLUSIONS In summary, TXL multi-targeted to down-regulate the metastatic markers in both in vitro and in vivo models. However, the effects of its bioactive fractions were not obvious. This study profoundly elucidated the anti-proliferative mechanism of TXL, which is vital for the development of future anti-cancer regime in Chinese medicinal formulations.

Abstract
The roots of Angelica sinensis [Angelica Sinensis Radix (ASR)] have been used as a common health food supplement for women's care for thousands of years in China. According to Asian tradition, ASR could be processed with the treatment of wine, which subsequently promoted the biological functions of ASR. By chemical and biological assessments, an orthogonal array design was employed here to determine the roles of three variable parameters in the processing of ASR, including oven temperature, baking time, and flipping frequency. The results suggested that oven temperature and baking time were two significant factors, while flipping frequency was a subordinate factor. The optimized condition of processing with wine therefore was considered to be heating in an oven at 80 °C for 90 min with flipping twice per hour. Under the optimized processing conditions, the solubilities of ferulic acid and Z-ligustilide from ASR were markedly increased and decreased, respectively. In parallel, the biological functions of processed ASR were enhanced in both anti-platelet aggregation and estrogenic activation; these increased functions could be a result of the altered levels of ferulic acid and Z-ligustilide in wine-processed ASR. Thus, the chemical and biological assessment of the processed ASR was in full accordance with the Chinese old tradition.

Abstract
Danggui Buxue Tang (DBT), a Chinese medicinal decoction that contains Radix Angelicae sinensis (Danggui) and Radix Astragali (Huangqi) at a ratio of 1:5, is used commonly for treating women's ailments. The present study explored the effects of this preparation on chronic fatigue syndrome (CFS). Rats were subjected to a combination of food restriction and forced swimming to induce CFS, and rats were gavaged once daily with either 12 or 24 g/kg DBT for 28 days. Body weights, T-cell subset counts, (3) H-TdR incorporation measurements and mRNA levels of IL-1β, TNF-α, NF-кB, p38MAPK and JNK were determined on days 14 and 28. The swimming endurance capacity was measured on day 28. Rats that received DBT exhibited increased body weight and endurance capacity, corrected T cell subsets counts, increased (3) H-TdR incorporation and decreased mRNA levels of IL-1β, TNF-α, NF-кB, p38MAPK and JNK compared with rats that did not receive DBT. The results indicate that DBT can ameliorate CFS through immune modulation and may act to normalize cytokines and their related signaling pathways.

Abstract
Angiogenesis plays an important role in a wide range of physiological processes and many diseases are associated with dysregulation of angiogenesis. Radix Astragali, commonly used in traditional Chinese medicine, is a potential candidate for treating such diseases. However, the biological effects of Radix Astragali on angiogenesis and its underlying mechanisms are yet to be elucidated fully. This study describes the angiogenic effects of Radix Astragali extract (RAE) on human umbilical vein endothelial cells (HUVEC) in vitro. It was shown that RAE treatment stimulated HUVEC to proliferate. A significant increase in migration was observed in RAE-treated HUVEC using the wound healing migration assay. In addition, a significant increase in the number of branching points was observed during endothelial cell capillary formation after RAE treatment. It was shown that RAE enhances vascular endothelial growth factor (VEGF) mRNA expression, and that a specific blocker of VEGF receptor 2 (KDR/Flk) inhibited the RAE-induced HUVEC proliferation. In addition, a decrease in the RAE-induced HUVEC proliferation was observed after treatment with inhibitors of phosphatidylinositol 3-kinase (PI3K), Akt and endothelial nitric oxide synthase (eNOS). Taken together, these data suggest that RAE is a potent stimulator of angiogenesis and that its pro-angiogenic effects involve the VEGF-KDR/Flk and PI3K-Akt-eNOS pathways.

The expression of erythropoietin triggered by danggui buxue tang, a Chinese herbal decoction prepared from radix Astragali and radix Angelicae Sinensis, is mediated by the hypoxia-inducible factor in cultured HEK293T cells. JOURNAL OF ETHNOPHARMACOLOGY 2010; 132:259-267. [PMID: 20723591 DOI: 10.1016/j.jep.2010.08.029] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/17/2010] [Revised: 07/02/2010] [Accepted: 08/09/2010] [Indexed: 05/29/2023]
Abstract
ETHNOPHARMACOLOGICAL EVIDENCE Danggui buxue tang (DBT), a Chinese medicinal decoction that is being commonly used as hematopoietic medicine to treating woman menopausal irregularity, contains two herbs: radix Astragali and radix Angelicae Sinensis. Pharmacological results indicate that DBT can stimulate the production of erythropoietin (EPO), a specific hematopoietic growth factor, in cultured cells. AIM OF THE STUDY In order to reveal the mechanism of DBT's hematopoietic function, this study investigated the activity of the DBT-induced EPO expression and the upstream regulatory cascade of EPO via hypoxia-induced signaling in cultured kidney fibroblasts (HEK293T). MATERIALS AND METHODS DBT-induced mRNA expressions were revealed by real-time PCR, while the change of protein expressions were analyzed by Western blotting. For the analysis of hypoxia-dependent signaling, a luciferase reporter was used to report the transcriptional activity of hypoxia response element (HRE). RESULTS The plasmid containing HRE, being transfected into HEK293T, was highly responsive to the challenge of DBT application. To account for the transcriptional activation of HRE, DBT treatment was shown to increase the mRNA and protein expressions of hypoxia-inducible factor-1α (HIF-1α). In addition, the activation of Raf/MEK/ERK signaling pathway by DBT could also enhance the translation of HIF-1α, suggesting the dual actions of DBT in stimulating the EPO expression in kidney cells. CONCLUSION Our study indicates that HIF pathway plays an essential role in directing DBT-induced EPO expression in kidney. These results provide one of the molecular mechanisms of this ancient herbal decoction for its hematopoietic function.
