Abstract
MAIN CONCLUSION Hydroxy(phenyl)pyruvic acid reductase from Actaea racemosa catalyzes dual reactions in reducing 4-hydroxyphenylpyruvic acid as well as β-hydroxypyruvic acid. It thus qualifies to be part of fukinolic and cimicifugic acid biosynthesis and also photorespiration. The accumulation of fukinolic acid and cimicifugic acids is mainly restricted to Actaea racemosa (Ranunculaceae) and other species of the genus Actaea/Cimicifuga. Cimicifugic and fukinolic acids are composed of a hydroxycinnamic acid part esterified with a benzyltartaric acid moiety. The biosynthesis of the latter is unclear. We isolated cDNA encoding a hydroxy(phenyl)pyruvic acid reductase (GenBank OR393286) from suspension-cultured material of A. racemosa (ArH(P)PR) and expressed it in E. coli for protein production. The heterologously synthesized enzyme had a mass of 36.51 kDa and catalyzed the NAD(P)H-dependent reduction of 4-hydroxyphenylpyruvic acid to 4-hydroxyphenyllactic acid or β-hydroxypyruvic acid to glyceric acid, respectively. The optimal temperature was at 38 °C and the pH optimum at pH 7.5. NADPH is the preferred cosubstrate (Km 23 ± 4 µM). Several substrates are accepted by ArH(P)PR with β-hydroxypyruvic acid (Km 0.26 ± 0.12 mM) followed by 4-hydroxyphenylpyruvic acid (Km 1.13 ± 0.12 mM) as the best ones. Thus, ArH(P)PR has properties of β-hydroxypyruvic acid reductase (involved in photorespiration) as well as hydroxyphenylpyruvic acid reductase (possibly involved in benzyltartaric acid formation).

Abstract
BACKGROUND Botanical reference materials (BRMs) generally account for the species, cultivar, and year and location of harvest that result in variability in the chemical composition that may lead to statistically significant differences using chemometric methods. OBJECTIVE To compare the chemical composition of five species of Actaea root BRMs, four herbal sources of A. racemosa root BRMs, and A. racemosa BRMS, and commercial roots and supplements using chemometric methods and selected pre-processing approaches. METHOD Samples were analyzed by flow injection mass spectrometry (FIMS), principal component analysis (PCA), and factorial multivariate analysis of variance (mANOVA). RESULTS Statistically significant (P = 0.05) compositional differences were found between three genera (Actaea, Panax, and Ginkgo), five species of Actaea (A. racemosa, A. cimicifuga, A. dahurica, A. pachypoda, and A. rubra) root BRMs, four herbal sources of A. racemosa root BRMs, and A. racemosa BRMS and commercial roots and supplements. The variability of 6% of the BRM variables was found to be quantitatively conserved and reduced the compositional differences between the four sources of root BRMs. Compositional overlap of A. racemosa and other Actaea BRMs was influenced by variation in technical repeats, pre-processing methods, selection of variables, and selection of confidence limits. Sensitivity ranged from 94 to 97% and specificity ranged from 21 to 89% for the pre-processing protocols tested. CONCLUSIONS Environmental, genetic, and chemometric factors can influence discrimination between species and authentic botanical reference materials. HIGHLIGHTS Frequency distribution plots derived from soft independent modeling of class analogy provide excellent means for understanding the impact of experimental factors.

Abstract
Twelve undescribed 15,16-seco-cycloartane triterpenoids, 15,16-seco-cimiterpenes C-N, as well as five previously reported analogs were isolated by NMR-tracking methods from the rhizomes of Cimicifuga acerina (Sieb. et Zucc.) Tanaka. Among them, 15,16-seco-cimiterpenes C-N were the first 15,16-seco-cycloartane triterpenoids featuring acetal or hemiacetal structures at C-15. The chemical structures of 15,16-seco-cimiterpenes C-N were determined based on comprehensive spectroscopic analysis, chemical method, and comparison with the previous literature data. After that, all these compounds were evaluated for their lipid-lowering effects on 3T3-L1 adipocytes.15,16-seco-cimiterpene D was found to exhibit a comparable reducing lipid effect at the concentration of 50 μM, with an inhibition rate at 35.96%.

Abstract
BACKGROUND Endometriosis (EMS) is a relapsing and estrogen-dependent disease. For endometriosis such as deep endometriosis and ovarian endometrioid cysts, surgery is the most effective treatment. Long-term follow-up showed that the recurrence rate of endometriosis after surgical treatment was high, so postoperative drugs were needed to reduce recurrence, and Gonadotropin-releasing hormone agonists (GnRH-a) were the most commonly used drug for postoperative management.GnRH-a may reduce the post-treatment endometriosis relapses by lowering the hormone levels in the body. However, the use of GnRH-a can give rise to perimenopausal symptoms, especially osteoporosis, bone loss, and bone pain, for which reason GnRH-a use is often limited. The add-back therapy is often used to alleviate the untoward effects caused by GnRH-a. However, long-term use of hormone drugs may lead to EMS recurrence, thrombosis, and breast cancer. Therefore, a safer and more effective drug is urgently needed to alleviate the untoward effects caused by GnRH-a. In recent years, scholars at home and abroad have found that isopropanolic Cimicifuga racemosa extract (ICR), as a plant extract, can better relieve the symptoms of perimenopausal women. At the same time, some studies have initially confirmed that black cohosh preparations can relieve the perimenopausal symptoms caused by GnRH-a treatment in EMS patients. OBJECTIVE To investigate the effect of black cohosh preparations on the bone metabolism of rat models with GnRH-a-induced perimenopausal symptoms. METHODS The rat models of perimenopausal symptoms were established by GnRH-a injection. and normal saline (NS injection) was used as the control. According to the modeling method and drug intervention, the rats were randomly divided into four groups: GnRH-a injection + saline intervention group (GnRH-a + NS), saline injection control + saline intervention group (NS + NS), GnRH-a injection + estradiol intervention group (GnRH-a + E2), and GnRH-a injection + black cohosh preparation intervention group (GnRH-a + ICR). The rat models were identified with the vaginal smear method, and then the corresponding drug intervention was administrated for 28 days. After the intervention, the rats were sacrificed. The rats' bone mineral density (BMD) of the distal femur was detected by a dual-energy X-ray bone density scanner. Rat tibia bone tissues were decalcified and made into slices. The pathological and morphological changes of rat tibial bones in each group were observed through HE staining. Histomorphometry parameters of rat tibial bones in each group, such as trabecular bone volume (TBV), trabecular thickness (TbTh), trabecular number (TbN), and trabecular spacing (TbSp), were detected and analyzed by using an automatic image analysis system. RESULTS (1) The BMD level of the distal femur in the GnRH-a + NS group was significantly lower than the NS + NS, GnRH-a + E2, and GnRH-a + ICR groups (P<0.01), the BMD levels in GnRH-a + E2 and GnRH-a + ICR groups were slightly lower than the NS + NS group, but there was no significant difference among the three groups (P>0.05). (2) The pathological changes of the tibia bones under the microscope in different groups were as follows: The tibia bone trabecular structure was normal in the NS + NS group, without trabecular thinning or fracture, and the arch structure was normal. In the GnRH-a + NS group, some trabecular structures tapered, the arch structure disappeared, but no obvious bone fracture was observed in the trabecula. In the GnRH-a + E2 and GnRH-a + ICR groups, the trabecular structures were normal, without trabecular bone thinning or fracture, and the arch structures were normal. (3) The TBV level of the GnRH-a + INS group was significantly lower than that of the NS + NS, GnRH-a + E2 and GnRH-a + ICR groups (P<0.01, P<0.05, P<0.01), while there was no significant difference among NS + NS, GnRH-a + E2 and GnRH-a + ICR groups (P>0.05). (4) The TbTh levels in the four groups had no significant difference (P>0.05). Compared with the NS + NS group, the TbTh levels in the GnRH-a + NS, GnRH-a + E2, and GnRH-a + ICR groups showed a descending tendency, while the TbTh levels in the GnRH-a + E2 and GnRH-a + ICR groups were slightly higher than that of the GnRH-a + NS group. However, such differences were not significant statistically (P>0.05). (5) Compared with the NS + NS group, the TbN levels in the GnRH-a + NS, GnRH-a + E2, and GnRH-a + ICR groups decreased remarkably (P<0.05). Compared with the GnRH-a + NS group, the TbN levels in the GnRH-a + E2 and GnRH-a + ICR groups showed a mild descending tendency, but such differences were not significant statistically (P>0.05). (6) The TbSp level of the GnRH-a + NS group was significantly higher than that of the NS + NS, GnRH-a + E2, and GnRH-a + ICR groups (P<0.01), while there was no significant difference among NS + NS, GnRH-a + E2 and GnRH-a + ICR groups (P>0.05). CONCLUSION The GnRH-a injection could achieve the desired effect. GnRH-a injection may lead to the loss of bone mass in rats. Black cohosh preparations, like estrogen, may have a protective effect on bone mass loss caused by GnRH-a injection.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cimicifuga dahurica (Turcz.) Maxim (C. dahurica) has a long history of treating breast cancer. From the Qing Dynasty to the Tang Dynasty and even earlier, C. dahurica has been documented in the treatment of breast carbuncle (Breast cancer is classified as breast carbuncle in Chinese medicine). In traditional prescriptions such as "Sheng Ge Decoction", "Sheng Ma Powder" and "Breast Carbuncle Pill", as the main medicine, C. dahurica plays an important role. At present, the systematic studies on the in vitro and in vivo effects of Cimicifuga against breast cancer are rare, especially the C. dahurica. AIM OF THE STUDY In this article, we evaluated the in vitro activity and in vivo effects of CREE (extract of the root of C. dahurica) against breast cancer, and discussed the possible mechanism of CREE in promoting breast cancer cell apoptosis. MATERIALS AND METHODS The main component in the CREE was analyzed by HPLC. The effects of CREE on the proliferation, migration and invasion of human breast cancer cells were evaluated through SRB, colony assay, LDH release, wound healing and transwell assay. The pro-apoptotic effect of CREE was investigated in Hochest33342 and Annexin V-FITC/PI assay. To verify the results of CREE in vivo effects, we applied nude mice subcutaneous xenograft experiments. The possible mechanism of CREE treating breast cancer was investigated through mitochondrial membrane potential and western blot experiments. RESULTS CREE contains cycloartane triterpene saponins. CREE can significantly inhibit the proliferation, migration and invasion of human breast cancer MCF-7 and MDA-MB-231 cells in vitro and it can effectively inhibit the growth of MDA-MB-231 cell subcutaneous tumors in vivo. Besides, we also found that CREE up-regulated the expression levels of Bax, caspase-9/3 and cytochrome C, and down-regulated the expression of Bcl-2. Therefore, regulation of the mitochondrial pathway may be one of the mechanisms by which CREE promotes breast cancer cell apoptosis. CONCLUSIONS CREE exhibits sufficient anti-breast cancer activity in vivo and in vitro, this study provides persuasive evidence for the further research and development of C. dahurica.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried rhizome of Cimicifuga heracleifolia Kom. (C. heracleifolia) is a popular traditional Chinese medicine, which has been extensively used in Asian countries for its anti-inflammatory, antipyretic and analgesic activities. However, further utilization and application of C. heracleifolia have been hampered due to a lack of full understanding of its active ingredients. AIM OF STUDY The present study aims for clarification of the systematical chemical profile of C. heracleifolia and the immunomodulatory effect of its main bioavailable component. MATERIALS AND METHODS Comprehensive chemical profile of C. heracleifolia was systematically analyzed by ultra-performance liquid chromatography hyphenated with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS). Xenobiotics after oral administration of C. heracleifolia extracts were investigated to hunt for bioavailable components. The immunomodulatory activity evaluation of cimigenoside was achieved on poly(I:C)-induced airway inflammation mouse and BEAS-2B cell models from aspects of neutrophil infiltration, lung inflammation by using microscope analysis, quantification of production and expression of inflammatory cytokine and chemokines by using ELISA and quantitative PCR. RESULTS By UPLC-Q-TOF/MS analysis, 110 compounds (including 81 triterpenoids, 21 cinnamic acid derivatives, and 8 other structure types) were identified or tentatively characterized in ethanolic extract of C. heracleifolia. Based on the data of chemical profile, xenobiotics of C. heracleifolia were subsequently analyzed, and triterpene glycosides were detected as the major bioavailable ingredients. Oral administration of cimigenoside, a representative triterpene glycoside, could prevent neutrophils infiltration in the lung due to suppression of the production of CXCL2 and CXCL10, and the expression of P-selectin, VCAM1 in poly(I:C)-induced airway inflammation model mice. Moreover, cimigenoside also inhibited the productions of inflammatory cytokines and chemokines from human airway epithelial cell line (BEAS-2B cells) induced by poly(I:C). CONCLUSION Triterpene glycosides were the main components of C. heracleifolia extract, and cimigenoside was considered as the effective component with immunomodulatory effect on the pulmonary immune system by oral administration.

Abstract
BACKGROUND Endometriosis (EMS) is an estrogen-dependent disease, which easily recurs after operation. Gonadotropin-releasing hormone agonist (GnRH-a), an estrogen-inhibiting drug, can effectively inhibit the secretion of gonadotropin by pituitary gland, so as to significantly decrease the ovarian hormone level and facilitate the atrophy of ectopic endometrium, playing a positive role in preventing postoperative recurrence. The application of GnRH-a can lead to the secondary low estrogen symptoms, namely the perimenopausal symptoms, and is a main reason for patients to give up further treatment. The add-back therapy based on sex hormones can well address the perimenopausal symptoms, but long-term use of hormones may cause the recurrence of EMS, as well as liver function damage, venous embolism, breast cancer and other risks, which has long been a heated topic in the industry. Therefore, it is necessary to find effective and safe anti-additive drugs soon. Studies at home and abroad show that, as a plant extract, isopropanolic extract of cimicifuga racemosa (ICR) can well relieve the perimenopausal symptoms caused by natural menopause. Some studies have preliminarily confirmed that black cohosh preparations can antagonize perimenopausal symptoms of EMS patients treated with GnRH-a after operation. OBJECTIVE To establish a rat model of perimenopausal symptoms induced by GnRH-a injection, for the purposes of laying a foundation for further research and preliminarily exploring the effect of black cohosh preparations on reproductive endocrine of the rat model. METHOD The rat model of perimenopausal symptoms was established by GnRH-a injection, and normal saline (NS injection) was used as the control. The rats were randomly divided into four groups according to different modeling methods and drug intervention schemes. GnRH-a injection + normal saline intervention group (GnRH-a + NS), normal saline injection control + normal saline intervention group (NS + NS), GnRH-a injection + estradiol intervention group (GnRH-a + E2), and GnRH-a injection + black cohosh preparations intervention group (GnRH-a + ICR). After modelling was assessed to be successful with the vaginal smear method, the corresponding drugs were given for intervention for 28d. In the process of rat modeling and drug intervention, the skin temperature and anus temperature of the rat tails were measured every other day, the body weights of the rats were measured every other day, and the dosage was adjusted according to the body weight. After the intervention was over, the serum sex hormone level, the uterine weight, the uterine index, and the endometrial histomorphology changes, as well as the ovarian weight, the ovarian index, and the morphological changes of ovarian tissues of each group were measured. RESULTS (1) The vaginal cell smears of the control group (NS + NS) showed estrous cycle changes, while other model rats had no estrous cycle of vaginal cells. (2) The body weight gains of the GnRH-a + NS, GnRH-a + E2 and GnRH-a + ICR groups were significantly higher than that of the NS + NS control group. The intervention with E2 and ICR could delay the weight gain trend of rats induced by GnRH-A. (3) After GnRH-a injection, the temperature of the tail and anus of rats showed an overall upward trend, and the intervention with E2 and ICR could effectively improve such temperature change. (4) The E2, FSH, and LH levels in the GnRH-a + NS, GnRH-a + E2, and GnRH-a + ICR groups were significantly lower than those in the NS + NS group (P < 0.01). The E2 level was significantly higher and the LH level was significantly lower in the GnRH-a + E2 group than those in the GnRH-a + NS and GnRH-a + ICR groups (P < 0.05). Compared with those of the GnRH-a + NS and GnRH-a + ICR groups, the FSH level of the GnRH-a + E2 group showed a slight downward trend, but the difference was not statistically significant (P > 0.05). There was no significant difference in the levels of sex hormones between the GnRH-a + NS group and GnRH-a + ICR group (P > 0.05). (5) Compared with those of the NS + NS group, the uterine weight and uterine index of the GnRH-a + NS, GnRH-a + E2 and GnRH-a + ICR groups significantly decreased (P < 0.01). In a comparison between the groups, the uterine weight and uterine index in the GnRH-a + NS and GnRH-a + ICR groups were significantly lower than those in the GnRH-a + E2 group (P < 0.01). There was a statistical difference in the uterine weight and uterine index between the GnRH-a + NS group and GnRH-a + ICR group (P > 0.05). (6) Compared with those of the NS + NS group, the ovarian weight and ovarian index of the GnRH-a + NS, GnRH-a + E2 and GnRH-a + ICR groups significantly decreased (P < 0.01). There was no statistical difference in the ovarian weight and ovarian index among the GnRH-a + E2, GnRH-a + NS and GnRH-a + ICR groups (P > 0.05). (7) Compared with those in the NS + NS group, the number of primordial follicles increased significantly, while the number of growing follicles and mature follicles decreased significantly in the GnRH-a + NS, GnRH-a + E2, and GnRH-a + ICR groups (P < 0.01), but there was a statistical difference in the total number of follicles among the four groups (P > 0.05). CONCLUSIONS The GnRH-a injection could achieve the desired effect. The animal model successfully achieved a significant decrease in the E2, FSH, and LH levels in rats, and could cause the rats to have rising body surface temperature similar to hot flashes in the perimenopausal period. The intervention with E2 and ICR could effectively relieve such "perimenopausal symptoms", and ICR had no obvious effect on the serum sex hormone level in rats.

Abstract
BACKGROUND Actaea racemosa L., also known as black cohosh, is a popular herb commonly used for the treatment of menopausal symptoms. Because of its purported estrogenic activity, black cohosh root extract (BCE) may trigger breast cancer growth. STUDY DESIGN/METHODS The potential effects of standardized BCE and its main constituent actein on cellular growth rates and steroid hormone metabolism were investigated in estrogen receptor alpha positive (ERα+) MCF-7 and -negative (ERα-) MDA-MB-231 human breast cancer cells. Cell numbers were determined following incubation of both cell lines with the steroid hormone precursors dehydroepiandrosterone (DHEA) and estrone (E1) for 48 h, in the presence and absence of BCE or actein. Using a validated liquid chromatography-high resolution mass spectrometry assay, cell culture supernatants were simultaneously analyzed for the ten main steroids of the estrogen pathway. RESULTS Inhibition of MCF-7 and MDA-MB-231 cell growth (up to 36.9%) was observed following treatment with BCE (1-25 µg/ml) or actein (1-50 µM). Incubation of MCF-7, but not of MDA-MB-231 cells, with DHEA and BCE caused a 20.9% reduction in DHEA-3-O-sulfate (DHEA-S) formation, leading to a concomitant increase in the androgens 4-androstene-3,17-dione (AD) and testosterone (T). Actein was shown to exert an even stronger inhibitory effect on DHEA-S formation in MCF-7 cells (up to 89.6%) and consequently resulted in 12- to 15-fold higher androgen levels compared with BCE. The formation of 17β-estradiol (E2) and its glucuronidated and sulfated metabolites was not affected by BCE or actein after incubation with the estrogen precursor estrone (E1) in either cell line. CONCLUSIONS The results of the present study demonstrated that actein and BCE do not promote breast cancer cell growth or influence estrogen levels. However, androgen formation was strongly stimulated by BCE and actein, which may contribute to their ameliorating effects on menopausal symptoms in women. Future studies monitoring the levels of AD and T upon BCE supplementation of patients are warranted to verify an association between BCE and endogenous androgen metabolism.

Abstract
In the market of botanical dietary supplements, Cimicifuga heracleifolia (CH) has always been considered as an adulterated species of Cimicifuga racemosa (CR), a conventional American herb with promising benefits to counteract troubles arising from the menopause. However, the detailed comparison of their therapeutic effects is lacking. In present study, the pharmacological and metabolomics studies were comparatively conducted between CH and CR in ovariectomized (OVX) female rats. Specifically, estrogen-like, anti-hyperlipidemia and anti-osteoporosis effects were evaluated through measuring serum biochemical parameters, histopathological examination and micro computed tomography (Micro-CT) scanning. At the same time, a gas chromatography-mass spectrometry (GC-MS)-based serum metabolomics method was employed to profile the metabolite compositional changes. As a result, both CR and CH displayed anti-osteoporosis and anti-hyperlipemia on menopause syndrome. Meanwhile, their potentials in improving the OVX-induced metabolic disorders were discovered. In conclusion, these results demonstrated that CH is therapeutically similar to CR in relieving menopausal symptoms and CH could be considered as a promising alternative to CR instead of an adulterant in the market of botanical dietary supplements.

Abstract
Botanical dietary supplements are complex mixtures with numerous potential sources of variation along the supply chain from raw plant material to the market. Approaches for determining sufficient similarity (ie, complex mixture read-across) may be required to extrapolate efficacy or safety data from a tested sample to other products containing the botanical ingredient(s) of interest. In this work, screening-level approaches for generating both chemical and biological-response profiles were used to evaluate the similarity of black cohosh (Actaea racemosa) and Echinacea purpurea samples to well-characterized National Toxicology Program (NTP) test articles. Data from nontargeted chemical analyses and gene expression of toxicologically important hepatic receptor pathways (aryl hydrocarbon receptor [AhR], constitutive androstane receptor [CAR], pregnane X receptor [PXR], farnesoid X receptor [FXR], and peroxisome proliferator-activated receptor alpha [PPARα]) in primary human hepatocyte cultures were used to determine similarity through hierarchical clustering. Although there were differences in chemical profiles across black cohosh samples, these differences were not reflected in the biological-response profiles. These findings highlight the complexity of biological-response dynamics that may not be reflected in chemical composition profiles. Thus, biological-response data could be used as the primary basis for determining similarity among black cohosh samples. Samples of E. purpurea displayed better correlation in similarity across chemical and biological-response measures. The general approaches described herein can be applied to complex mixtures with unidentified active constituents to determine when data from a tested mixture (eg, NTP test article) can be used for hazard identification of sufficiently similar mixtures, with the knowledge of toxicological targets informing assay selection when possible.

Abstract
The medicinal plant Actaea racemosa is a perennial, whose rhizome (black cohosh rhizome) is usually wild harvested on a multiton scale to meet market requirements. Since this North American species is increasingly endangered, cultivation is needed. Even though studies prove that cultivation is possible, it has not been widely established. This may be due to a different quality of cultivated material, which does not comply with current pharmacopoeial requirements. This study compares contents and chromatographic fingerprints of phenolic acids and triterpene glycosides in different types of black cohosh rhizomes. Commercial batches from wild harvests were compared to individual plants from the wild and from cultivation. Phenolic acids' contents and profiles were generally comparable between wild harvesting and cultivation. On the contrary, the total triterpene glycoside content was significantly lower in cultivation (p ≤ 0.001). In individual plants, different profiles of triterpene glycosides occurred. Possibly, specimen or chemotype selection for cultivation would cause a shift of the triterpene glycoside profile of cultivation batches away from the common pattern found in batches from wild harvesting. Potentially, such differences have an impact on the efficacy of black cohosh herbal products, if cultivated plant material is used for manufacturing.

Abstract
The nucleotide sequence of a BAHD hydroxycinnamoyltransferase was amplified from Actaea racemosa (Ranunculaceae) and expressed in E. coli. The protein catalysed the formation of cimicifugic acids and thus is named hydroxycinnamoyl-CoA:piscidic acid hydroxycinnamoyltransferase (ArHPT1; cimicifugic acid synthase). Actaea racemosa (syn. Cimicifuga racemosa) is known to contain triterpene lactone glycosides and cimicifugic acids. The latter are esters of various hydroxycinnamic or benzoic acids with piscidic or fukiic acid. Amplification of a nucleotide sequence from A. racemosa, that was already known as HCT1 from an EST approach, and its expression in E. coli resulted in a protein that was able to catalyse the formation of several cimicifugic acids. For the characterisation of this hydroxycinnamoyltransferase (hydroxy)cinnamoyl-coenzyme A thioesters were synthesised as donor substrates and piscidic acid isolated as acceptor substrate. The lowest Km-value with 6.8 µM was determined for p-coumaroyl-CoA. More than 30 possible acceptor substrates were tested, but only piscidic acid and putatively fukiic acid were accepted. The apparent Km-value for piscidic acid was 32.3 µM. High expression of the hydroxycinnamoyltransferase gene was found in roots, but the content of cimicifugic acids was higher in leaves and flowers than in roots. This work describes for the first time a biosynthetic step in the formation of cimicifugic acids catalysed by a so far uncharacterised hydroxycinnamoyltransferase accepting piscidic acid as acceptor substrate thus being a hydroxycinnamoyl-CoA:piscidic acid hydroxycinnamoyltransferase (ArHPT1; cimicifugic acid synthase).

Abstract
Human enterovirus 71 (EV-A71) infections cause a wide array of diseases ranging from diarrhoea and rashes to hand-foot-and-mouth disease and, in rare cases, severe neurological disorders. No specific antiviral drug therapy is currently available. Extracts from 75 Chinese medicinal plants selected for antiviral activity based on the Chinese pharmacopeia and advice from traditional Chinese medicine clinicians were tested for activity against EV-A71. The aqueous extract of the rhizome of Cimicifuga heracleifolia (Sheng Ma) and Arnebia euchroma (Zi Cao) showed potent antiviral activity. The active fractions were isolated by bioassay-guided purification, and identified by a combination of high-resolution mass spectrometry and nuclear magnetic resonance. Fukinolic acid and cimicifugic acid A and J, were identified as active anti-EV-A71 compounds for C. heracleifolia, whereas for A. euchroma, two caffeic acid derivatives were tentatively deduced. Commercially available fukinolic acid analogues such as L-chicoric acid and D-chicoric also showed in vitro micromolar activity against EV-A71 lab-strain and clinical isolates.

Abstract
BACKGROUND Cimicifuga racemosa extract is a well-established therapy for menopausal symptoms. The mechanisms underlying the multiple therapeutic effects of Cimicifuga extract, e.g. reducing hot flushes and profuse sweating are not well defined. Recent studies revealed pronounced effects of Ze 450, a Cimicifuga racemosa extract that was produced by a standardized procedure, on energy metabolism through activation of AMP-activated protein kinase in vitro and beneficial anti-diabetic effects in vivo. PURPOSE The aim of the study was to investigate the effects of Ze 450 on energy metabolism. Since mitochondria are the key regulators of cellular energy homeostasis, we wanted to elucidate whether Ze 450 affects mitochondrial resilience and can provide protection against oxidative damage in neuronal and liver cells. METHODS/STUDY DESIGN In this study, we investigated the effects of Ze 450 (1-200 µg/ml) on mitochondrial integrity and function, and cell viability in models of oxidative stress induced by erastin and RSL-3 in neuronal and liver cells. The effects of Ze 450 in control conditions and after induction of oxidative stress were analyzed using FACS for detecting lipid peroxidation (BODIPY), mitochondrial ROS formation (MitoSOX), mitochondrial membrane potential (TMRE) and cell death (AnnexinV/PI staining). Furthermore, we determined metabolic activity (MTT assay), ATP levels and mitochondrial respiration and glycolysis (oxygen consumption rates, extracellular acidification rates; Seahorse). RESULTS Ze 450 preserved mitochondrial integrity and ATP levels, and prevented mitochondrial ROS formation, loss of mitochondrial membrane potential and cell death. Notably, Cimicifuga racemosa extract alone did not alter mitochondrial ROS levels, and subtle inhibitory effects on cell proliferation were reversed after withdrawal of the extract. In addition, Ze 450 did not exert toxic effects to liver cells, but rather protected these from the oxidative challenge. Further analysis of the mitochondrial oxygen consumption rate and the extracellular acidification rate revealed that Ze 450 mediated a switch from mitochondrial respiration to glycolysis, and this metabolic shift was a prerequisite for the protective effects against oxidative damage. CONCLUSION In conclusion, the bioenergetic shift induced by Ze 450 exerted protective effects in different cell types, and offers promising therapeutic potential in age related diseases involving oxidative stress and mitochondrial damage.

Abstract
Cholinesterases (ChEs) are enzymes that break down neurotransmitters associated with cognitive function and memory. We isolated cinnamic acids (1 and 2), indolinones (3 and 4), and cycloartane triterpenoid derivatives (5-19) from the roots of Cimicifuga dahurica (Turcz.) Maxim. by chromatography. These compounds were evaluated for their inhibitory activity toward ChEs. Compound 1 was determined to have an IC50 value of 16.7 ± 1.9 μM, and to act as a competitive inhibitor of acetylcholinesterase (AChE). Compounds 3, 4 and 14 were found to be noncompetitive with IC50 values of 13.8 ± 1.5 and 6.5 ± 2.5 μM, and competitive with an IC50 value of 22.6 ± 0.4 μM, respectively, against butyrylcholinesterase (BuChE). Our molecular simulation suggested each key amino acid, Tyr337 of AChE and Asn228 of BuChE, which were corresponded with potential inhibitors 1, and 3 and 4, respectively. Compounds 1 and 4 were revealed to be promising compounds for inhibition of AChEs and BuChEs, respectively.

Abstract
This study was designed to search for novel anti-cancer compounds from natural plants. The 70% ethanolic extract from the rizhomes of Cimicifuga dahurica (Turcz.) Maxim. (Ranunculaceae) was found to possess significant in vitro anti-proliferative effects on MCF-7 breast cancer cells. A phytochemical investigation using assay-guided fractionation of the ethanolic extract of C. dahurica resulted in the isolation of one new phenolic amide glycoside 3, two new lignan glycosides 4 and 7, one new 9,19-cycloartane triterpenoid glycoside 6, and thirteen known constituents 1, 2, 5, and 8⁻17. The structures of 3, 4, 6, and 7 were established using contemporary NMR methods and from their HRESIMS data. The anti-proliferative effects of isolated compounds were evaluated using the BrdU-proliferation kit. Five among the 17 isolated compounds showed significant anti-proliferative effects (p ≤ 0.05), wherein compound 7 showed the most significant anti-proliferative and cell cycle arresting effect (p ≤ 0.05) which followed a dose dependent manner. Western blot protein expression analysis showed a down expression of c-Myc and cyclin D1 which further elucidated the anti-proliferation mechanism of compound 7 while apoptotic effects were found in association with Bcl-2 family protein expression variations. Conclusively this study reports the isolation and identification of 17 compounds from C. dahurica, including four novel molecules, in addition to the fact that compound 7 possesses significant anti-proliferative and apoptotic effects in vitro that may require further exploration.

Abstract
Actaea racemosa (black cohosh) has a history of traditional use in the treatment of general gynecological problems. However, the plant is known to be vulnerable to adulteration with other cohosh species. This study evaluated the use of shortwave infrared hyperspectral imaging (SWIR-HSI) in tandem with chemometric data analysis as a fast alternative method for the discrimination of four cohosh species (Actaea racemosa, Actaea podocarpa, Actaea pachypoda, Actaea cimicifuga) and 36 commercial products labelled as black cohosh. The raw material and commercial products were analyzed using SWIR-HSI and ultra-high-performance liquid chromatography coupled to mass spectrometry (UHPLC-MS) followed by chemometric modeling. From SWIR-HSI data (920 - 2514 nm), the range containing the discriminating information of the four species was identified as 1204 - 1480 nm using Matlab software. After reduction of the data set range, partial least squares discriminant analysis (PLS-DA) and support vector machine discriminant analysis (SVM-DA) models with coefficients of determination (R2 ) of ≥ 0.8 were created. The novel SVM-DA model showed better predictions and was used to predict the commercial product content. Seven out of 36 commercial products were recognized by the SVM-DA model as being true black cohosh while 29 products indicated adulteration. Analysis of the UHPLC-MS data demonstrated that six commercial products could be authentic black cohosh. This was confirmed using the fragmentation patterns of three black cohosh markers (cimiracemoside C; 12-β,21-dihydroxycimigenol-3-O-L-arabinoside; and 24-O-acetylhydroshengmanol-3-O-β-D-xylopyranoside). SWIR-HSI in conjunction with chemometric tools (SVM-DA) could identify 80% adulteration of commercial products labelled as black cohosh.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plants of the genus Cimicifuga have long been used as an ethnomedicine in China, Europe, and North America for its high medicinal value and health benefits. Their dried rhizomes are widely used for treating wind-heat headache, toothache, aphtha, sore throat, measles, spot poison, archoptosis, and uterine prolapse. In addition, it is used as a dietary supplement for preventing women menopausal symptoms and osteoporosis. AIM OF THE REVIEW This paper aims to provide up-to-date information on the genus Cimicifuga, including botanical characterization, medicinal resources, traditional medicinal uses, phytochemistry, quality control, pharmacological research as well as the toxicology. The possible structural-activity relationships and molecular mechanisms of the bioactive constituents are discussed in ways that contribute to the structural optimization and preclinical safety assessment for further drug design. MATERIALS AND METHODS The relevant information on Cimicifuga was collected from scientific databases (such as Google Scholar, PubMed, SciFinder Scholar, Science Direct, CNKI, Baidu Scholar, Web of Science, China Knowledge Resource Integrated Database), Chinese herbal classics, ethnobotanical books, PhD and MSc dissertations, Chinese Pharmacopoeia, published articles in peer-reviewed journals, local magazines, and unpublished materials. In addition, the Plant List (TPL, www.theplantlist.org) was also used to validate the scientific names and synonyms of this plant. The literature cited in this review dated from 1953 to 2017. RESULTS The majority of chemical constituents of this plant include triterpenoid glycosides, phenylpropanoids, nitrogenous compounds, chromones, flavonoids and 4α-methyl steroid. Among them, the primary bioactive constituents are believed to be present in the triterpene glycoside fraction. To date, investigation of seven Cimicifuga spp. plants led to the identification of more than 457 compounds. Years of pharmacological research proved that the crude extracts and certain pure compounds obtained from Cimicifuga exhibited menopausal syndrome-treatment, anti-osteoporosis, antiviral, antitumor, antioxidant and antiangiogenic activities. On the other hand, Cimicifuga plant-induced toxicities of liver, cardiovascular, central and peripheral nervous systems have also been reported. Therefore, safety consideration should be placed into a high priority for herbal medicine Cimicifuga therapy in the early stages of development and clinical trials. CONCLUSIONS This review presents information on botany, medicinal resources, and traditional medicinal history of some Cimicifuga plants. Modern pharmacology researchers have validated many traditional uses of Cimicifuga species. As the quality control and safety assessment of Cimicifuga plants is still incomplete, only a small part of the plant is permitted to be used as medicines. Expansion of medicinal resources in Cimicifuga is urgently needed to enable its full use. Currently research primarily focuses on the triterpenoid glycosides but there are many other types of compounds which may possess new biological activities however the systematic studies of these compounds are lacking. Extensive study is required on Cimicifuga plant before it can be fully used in clinics as a potent drug candidate.

Abstract
Rhizomes of Actaea racemosa L. (formerly Cimicifuga racemosa) gained increasing interest as a plant-derived drug due to its hormone-like activity and the absence of estrogenic activity. According to the Current Good Manufacturing Practices guidelines and pharmacopeial standards, quality assessment of herbal starting materials includes tests on identity and substitution, as well as quantification of secondary metabolites, usually by HPTLC and LC methods. To reduce the laboratory effort, we investigated near-infrared spectroscopy for rapid species authentication and quantification of metabolites of interest.Near-infrared spectroscopy analysis is carried out directly on the milled raw plant material. Spectra were correlated with reference data of polyphenols and triterpene glycosides determined by LC/diode array detection and LC/evaporative light scattering detection, respectively. Quantification models were built and validated by cross-validation procedures. Clone plants, derived by vegetative propagation, and plants of a collection from different geographical origins cultivated in Berlin were analysed together with mixed batches from wild harvests purchased at wholesalers.Generally, good to excellent correlations were found for the overall content of polyphenols with coefficients of determination of R2 > 0.93. For individual polyphenols such as fukinolic acid, only models containing clone plants succeeded (R2 > 0.92). For the total content of triterpene glycosides, results were generally worse in comparison to polyphenols and were observed only for the mixed batches (R2 = 0.93).Next to quantitative analysis, near-infrared spectroscopy was proven as a rapid alternative to other, more laborious methods for species authentication. Near-infrared spectroscopy was able to distinguish different Actaea spp. such as the North American Actaea cordifolia and the Asian Actaea cimicifuga, Actaea dahurica, Actaea heracleifolia, and Actaea simplex.

Abstract
A phytochemical assay-guided fractionation of the 95% ethanol extract of Cimicifuga dahurica roots afforded 29 9,19-cycloartane triterpenoid glycosides, including the new cimiricasides A-F (1-6). The structures of 1-6 were established using contemporary NMR methods and from the HRESIMS data, and the sugar moiety in each case was confirmed by acid hydrolysis and subsequent GC/MS analysis. Compounds 2, 4, 5, 7-9, 18, 25, and 29 showed soluble epoxide hydrolase inhibitory effects with IC50 values of 0.4 ± 0.1 to 24.0 ± 0.2 μM. The compounds were analyzed by enzyme kinetic studies to explore the binding mode between the ligand and receptor. Compounds 4 (mixed type), 8, 18, and 29 (noncompetitive type) bound to a preferred allosteric site, while compounds 2, 5, 7, 9, and 25 had competitive interactions at the active site. The binding mechanism of selected inhibitors was investigated using molecular docking and dynamics simulations.

Abstract
BACKGROUND Methylglyoxal (MG) is an endogenous product of glucose metabolism known to be toxic to cells and to be present in elevated concentrations under certain pathophysiological conditions. In the present study the effect of actein isolated from black cohosh on MG-induced cytotoxicity was investigated in MC3T3-E1 osteoblastic cells. RESULTS Treatment of MC3T3-E1 osteoblastic cells with actein prevented MG-induced cell death and the production of intracellular reactive oxygen species (ROS), mitochondrial superoxide, inflammatory cytokines and soluble receptor for advanced glycation end-products (sRAGE). In addition, actein increased the activity of glyoxalase I and levels of reduced glutathione (GSH) and the transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2). These findings suggest that actein protects against MG-induced cell damage by reducing oxidative stress and increasing MG detoxification. Treatment with actein prior to MG exposure reduced MG-induced mitochondrial dysfunction by preventing mitochondrial membrane potential dissipation and adenosine triphosphate (ATP) loss. Additionally, peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α), nuclear respiratory factor 1 (NRF-1) and nitric oxide (NO) levels were significantly increased by actein, suggesting that actein may induce mitochondrial biogenesis. CONCLUSION This study demonstrates that actein reduces MG-induced damage in osteoblastic MC3T3-E1 cells by enhancing antioxidant defenses, the glyoxalase system and mitochondrial biogenesis. © 2016 Society of Chemical Industry.

Abstract
INTRODUCTION The medicinal plant Actaea racemosa L. (Ranunculaceae, aka black cohosh) is widely used to treat climacteric complaints as an alternative to hormone substitution. Recent trials prove efficacy and safety of the approved herbal medicinal products from extracts of pharmaceutical quality. This led to worldwide increasing sales. A higher demand for the plant material results in problems with economically motivated adulteration. Thus, reliable tools for herbal drug authentication are necessary. OBJECTIVE To develop an economical, plain, and rapid method to distinguish between closely related American and Asian Actaea species, using securely established and resilient analytical methods coupled to a chemometric evaluation of the resulting data. METHODOLOGY We developed and validated a RP-PDA-HPLC method including an extraction by ultra-sonication to determine the genuine contents of partly hydrolysis-sensitive polyphenols in Actaea racemosa roots and rhizomes, and applied it to a large number of 203 Actaea samples consisting of seven species. RESULTS We were able to generate reliable data with regards to the polyphenolic esters in the samples. The evaluation of this data by principle component analysis (PCA) made a discrimination between Asian Actaea species (sheng ma), one American Actaea species (Appalachian bugbane), and A. racemosa possible. CONCLUSION The developed RP-PDA-HPLC method coupled to PCA is an excellent tool for authentication of the Actaea racemosa herbal drug, and can be a powerful addition to the TLC methods used in the dedicated pharmacopoeias, and is a promising alternative to expensive and lots of expertise requiring methods.

Abstract
High-resolution-melting analysis (HRM) is a new technology derived from q PCR and is widely used in the study of polymorphism, genotyping, and single nucleotide mutation. Advantages of HRM include cost-effectiveness and time-efficiency over PCR-based genotyping. However, the application of HRM in the authentication of herbal products is still limited with few studies on the classification and identification of herbal products. In this study, Cimicifugae Rhizoma was used as an example to verify the stability and accuracy of HRM technique in identification of Chinese materia medica. HRM assay was established for identification based on ITS2 region of Cimicifugae Rhizomas and its adulterants(including 41 samples). Our findings showed that HRM allows not only the identification of adulteration but also the quantification of the most common admixture. This study is significant for better quality in the verification of the authenticity of herbal medicine. The method is promising for future identification of traditional Chinese medicinal materials.

Abstract
AIMS This work aims to study the in vitro and in vivo antitumor activities of tetracyclic triterpenoids compounds actein and 26-deoxyactein. Further, the mechanism is investigated. METHODS In vitro, a modified MTT method was used to assay the cytotoxicities of actein and 26-deoxyactein in 12 human tumor cell lines. In vivo, mouse sarcoma S180 and human lung cancer A549 cells were respectively implanted subcutaneously in ICR mice and nude mice to establish implanted tumor models. Flow cytometry (FCM) was used to assay the cycle distribution of the tumor cells. Immunohistochemistry was used to measure CD31-positive expression in the xenogrft tumor by analyzing microvessel density (MVD). In addition, acute toxicities of actein and 26-deoxyactein were also evaluated. RESULTS Actein and 26-deoxyactein inhibited the proliferation of the 12 human cancer cell lines tested with the values of 50% inhibitory concentrations (IC50) between 12.29 and 88.39 μg/mL. In vivo, both actein (3-27 mg/kg) and 26-deoxyactein (3-27 mg/kg) significantly inhibited the growth of the implanted sarcoma S180 in a dose-dependent manner. Actein (10, 30 mg/kg) and 26-deoxyactein (10, 30 mg/kg) markedly inhibited the xenograft growth with T/C (%) values of 38%, 55% for actein, and 35%, 49% for 26-deoxyactein. Compared with the vehicle control, actein (10, 30 mg/kg) and 26-deoxyactein (10, 30 mg/kg) significantly reduced the MVD in the xenograft tumor. The FCM result showed that human leukemia HL-60 cells were arrested at G₁ phase after treated with either actein (6.25-25 μg/mL) or 26-deoxyactein (6.25-25 μg/mL) for 48 h. A limited trial in mice showed that both of the minimal lethal doses (MLDs) of actein and 26-deoxyactein were over 5 g/kg. CONCLUSIONS Both actein and 26-deoxyactein have low toxicities. Importantly, both these two tetracyclic triterpenoids compounds isolated from rhizome of Cimicifuga foetida L. have significant antitumor activities in vitro and in vivo, which is associated with cell cycle arrest and angiogenesis inhibition.

Abstract
Investigating the phytochemical equivalence of the aerial parts of Actaea racemosa (syn. Cimicifuga racemosa) relative to the widely used roots/rhizomes, this study provides a perspective for the potential use of renewable ("green") plant parts as a source of black cohosh botanical preparations. In addition to the characterization of Nω-methylserotonin as one representative marker of the Actaea alkaloids, nine cycloartane triterpenes were isolated and characterized, including the two new triterpene glycosides (1S,15R)-1,15,25-trihydroxy-3-O-β-d-xylopyranosyl-acta-(16S,23R,24R)-16,23;16,24-binoxoside (1) and 3-O-α-l-arabinopyranosyl-(1S,24R)-1,24,25-trihydroxy-15-oxo-acta-(16R,23R)-16,23-monoxoside (2). Their structures were elucidated by spectroscopic data interpretation. The relative configuration of 1 was deduced by (1)H iterative full-spin analysis (HiFSA), making it the first example of the complete analysis of the complex (1)H NMR spectrum of a triterpene glycoside. In addition to the new compounds 1 and 2, the aerial plant parts were shown to contain the previously known binoxosides 3, 4, 6, and 7, the monoxoside 8, and the binoxols 5 and 9. Overall, the metabolome of the aerial plant parts consists of a variety of Actaea triterpenes, similar to those found in roots/rhizomes, a tendency toward C-1 and C-7 hydroxylation of the cycloartanol skeleton, a greater abundance of aglycones, and the presence of comparable amounts of Nω-methylserotonin.

Abstract
Flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry, two metabolic fingerprinting methods, and DNA sequencing were used to identify and authenticate Actaea species. Initially, samples of Actaea racemosa from a single source were distinguished from other Actaea species based on principal component analysis and soft independent modeling of class analogies of flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry metabolic fingerprints. The chemometric results for flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry agreed well and showed similar agreement throughout the study. DNA sequencing using DNA sequence data from two independent gene regions confirmed the metabolic fingerprinting results. Differences were observed between A. racemosa samples from four different sources, although the variance within species was still significantly less than the variance between species. A model based on the combined A. racemosa samples from the four sources consistently permitted distinction between species. Additionally, the combined A. racemosa samples were distinguishable from commercial root samples and from commercial supplements in tablet, capsule, or liquid form. DNA sequencing verified the lack of authenticity of the commercial roots but was unsuccessful in characterizing many of the supplements due to the lack of available DNA.

Abstract
This study aims to observe the effects of estradiol and Cimicifuga racemosa on the lacrimal gland and submandibular gland of ovariectomized rats. We randomly divided 20 adult female SD rats into four groups-a sham-operated group (SHAM), ovariectomized (OVX) group, ovariectomized group treated with estradiol (OVX+ E), and ovariectomized group treated with the isopropanolic extract of Cimicifuga racemosa (OVX+ iCR). The SHAM group and OVX group used distilled water to instead the drugs. Two weeks after ovariectomy, the estradiol and iCR were administered for 4 weeks. Next, we used H&E staining and electron microscopy to observe any histological changes in the lacrimal and submandibular glands and immunohistochemical staining to observe the expressions of cleaved caspase-3 (Casp-3) and Cu-Zn SOD (superoxide dismutase). The H&E staining find that both drugs can prevent the cells of area from shrinkage in the two kinds of gland. But under the electron microscopy, estradiol and iCR have different efficacy. Estradiol is more effective at protecting mitochondria in lacrimal gland acinar cells than iCR, and iCR is more effective at suppressing endoplasmic reticulum expansion than estradiol. Both estradiol and iCR have a similar protective function on mitochondria in the submandibular gland. The protective function of the two glands may inhibit apoptosis by suppressing the expression of Casp-3. In addition, iCR increases the expression of Cu-Zn SOD in duct system of submandibular gland. The results suggest that both estradiol and iCR confer a protective effect on the lacrimal and submandibular glands of ovariectomized rats via different mechanisms.

Abstract
A phytochemical study on the rhizomes of Cimicifuga foetida resulted in the isolation of two new cycloartane triterpenoids (1 and 2), eight new cycloartane glycosides (3-10), and six known cycloartane glycoside analogues (11-16). The structures of 1-10 were determined by application of spectroscopic methods, with the absolute configuration of 1 determined by X-ray crystallography. Compounds 1-6, as three pairs of epimers at C-10 and C-24, belong to a seven-membered-ring variant of 9,10-seco-9,19-cycloartane triterpenoids, and glycosides 3-10 were found to be 3-O-β-D-xylopyranosides. The cytotoxicity of the isolates was evaluated against five selected human tumor cell lines, and the known compounds 15 and 16 showed cytotoxicity against the hepatocellular carcinoma SMMC-7721 cell line with IC50 values of 5.5 and 6.3 μM, respectively.

Abstract
INTRODUCTION It was the aim of the present experiments to examine potential antidiabetic effects of the Cimicifuga racemosa extract Ze 450. METHODS Ze 450 and some of its components (23-epi-26-deoxyactein, protopine and cimiracemoside C) were investigated in vitro for their effects on AMP-activated protein kinase (AMPK) compared to metformin in HepaRG cells. Ze 450 (given orally (PO) and intraperitonally (IP)), metformin (PO) and controls were given over 7 days to 68 male ob/ob mice. Glucose and insulin concentrations were measured at baseline and during an oral glucose tolerance test (OGTT). RESULTS Ze 450 and its components activated AMPK to the same extent as metformin. In mice, Ze 450 (PO/IP) decreased significantly average daily and cumulative weight gain, average daily food and water intake, while metformin had no effect. In contrast to metformin, PO Ze 450 virtually did not change maximum glucose levels during OGTT, however, prolonged elimination. Ze 450 administered PO and IP decreased significantly post-stimulated insulin, whereas metformin did not. HOMA-IR index of insulin resistance improved significantly after IP and PO Ze 450 and slightly after metformin. In summary, the results demonstrate that Ze 450 reduced significantly body weight, plasma glucose, improved glucose metabolism and insulin sensitivity in diabetic ob/ob mice. In vitro experiments suggest that part of the effects may be related to AMPK activation. CONCLUSIONS Ze 450 may have utility in the treatment of type 2 diabetes. However, longer term studies in additional animal models or patients with disturbed glucose tolerance or diabetes may be of use to investigate this further.

Abstract
BACKGROUND Owing to their potential to act as estrogen receptor modulators and interfere with aromatase enzyme in animal studies, phytoestrogens (PE) may be useful as part of ovulation induction for polycystic ovary syndrome (PCOS). PATIENTS AND METHODS Patients <35 years, presenting with infertility and PCOS, were included and randomly allocated to either group I (clomiphene citrate; CC) or group II (CC plus Cimicifugae racemosae; CR). Primary outcome was pregnancy rate. Secondary outcomes included ovulation, midcycle serum estradiol and luteinizing hormone (LH) as well as mid-luteal serum progesterone. RESULTS Analysis included 98 patients in group I versus 96 patients in group II. Both groups were matched regarding demographics and basic data. Significant differences were elicited when comparing days until HCG injection (15.0 ± 1.7 versus 12.0 ± 1.9, p=0.91), endometrial thickness (mm) (8.5 ± 1.9 versus 12.5 ± 1.9, p<0.001), serum levels of mid-luteal and midcycle estradiol (p<0.001; Figure 2), LH (IU/ml) (p<0.001) as well as mid-luteal progesterone (p<0.001). PE plus CC group had significantly higher clinical pregnancies per cycle (33/192 (17.2%) versus 71/204 (34.8%), p<0.01), compared to the CC only group. CONCLUSIONS Adding CR to clomiphene-induction cycles with timed intercourse in polycystic ovarian syndrome improves cycle outcomes and pregnancy rates.

Abstract
BACKGROUND Consumption of herbal supplements in the developed world remains high. Cimicifuga racemosa (C. racemosa) extract, or black cohosh, is widely used as a hormone replacing and an anti-inflammatory agent, and has been shown to cause idiosyncratic hepatitis. The mechanism of acute liver injury in those cases is unclear. To date, hepatotoxic effects of C. racemosa have been studied mostly in vitro and in animal models. Data on human tissue is extremely limited, and mostly confined to histological findings of explanted livers. METHODS We evaluated clinical data and examined surgical diagnostic liver biopsy specimens obtained from two female patients, who developed acute submassive liver necrosis, following consumption of C. racemosa. Both patients presented with acute elevation of liver enzymes, cholestasis, absence of reactivity to hepatitis A, B and C antibodies, and weak non-specific positivity for autoimmune serological markers. Initial histological interpretation of the biopsies, with focus on hepatic parenchyma and portal tracts, was done by light microscopy, followed by special stain series and immunohistochemical studies, including Cam 5.2, AE1/AE3, reticulin, α-actin, sirius red, and PAS with diastase. Areas of prominent lymphocytic infiltration of the periportal liver plate, observed microscopically, were further evaluated by electron microscopy (EM). 4HNE adduction study, an immunofluorescent assay, was performed to detect products of the oxidative damage and their localization in the liver parenchyma. RESULTS Oxidative damage was evident by accumulation of 4HNE protein adducts in the cytoplasm of hepatocytes, secondary lysosomes and macrophages. We hypothesize that the adducted proteins, accumulated in the liver parenchyma, serve as autoantigens, which provoke an autoimmune response, and cause migration of lymphocytes to the affected regions. The formation of immunological synapses between hepatocytes and lymphocytes, predominantly T-lymphocytes, is demonstrated by electron microscopy. The autoimmune response induces piecemeal, or troxis necrosis of hepatocytes, a well described biological phenomenon, where lymphocytes gradually remove hepatocytes in a piecemeal fashion, slowly consuming them and leaving fragments of liver cells, or nubbins of anuclear cytoplasm of liver cell, at the interface between lymphocytes and hepatocytes. CONCLUSION The pattern of pathological injury of liver cells in both patients, following consumption of black cohosh, is identical to troxis necrosis, seen during autoimmune hepatitis. Recognition of the possibility of the acute hepatic injury by the herbal supplement black cohosh is essential for early accurate diagnosis, and timely patient management.

Abstract
The medicinal plants of Huang-qi (Radix Astragali) and Sheng-ma (Cimicifuga foetida) demonstrate significantly better antioxidant effects when used in combination than when used alone. However, the bioactive components and interactional mechanism underlying this synergistic action are still not well understood. In the present study, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay was employed to investigate the antioxidant capacity of single herbs and their combination with the purpose of screening synergistic antioxidant compounds from them. Chromatographic isolation was performed on silica gel, Sephadex LH-20 columns and HPLC, and consequently to yield formononetin, calycosin, ferulic acid and isoferulic acid, which were identified by their retention time, UV λmax, MS and MS/MS data. The combination of isoferulic acid and calycosin at a dose ratio of 1∶1 resulted in significant synergy in scavenging DPPH radicals and ferric reducing antioxidant power (FRAP) assay. Furthermore, the protective effects of these four potential synergistic compounds were examined using H2O2-induced HepG2 Cells bioassay. Results revealed that the similar synergy was observed in the combination of isoferulic acid and calycosin. These findings might provide some theoretical basis for the purported synergistic efficiency of Huang-qi and Sheng-ma as functional foods, dietary supplements and medicinal drugs.

Abstract
Menopausal symptoms management with high-quality plant extracts from Actaea (Cimicifuga. racemosa rootstock is well-established. Efficacy and safety are supported by research and clinical trials since several decades and backed up by official monographs. However, the recent published Cochrane review on black cohosh neglects major evidence for beneficial effects. The authors' negative conclusions are questionable and call for reply and clarification. Our careful reconsideration of all appropriate placebo-controlled clinical studies reveals a standardized mean difference of 0.385 in favor of black cohosh (p < 0.0001).

Abstract
OBJECTIVE To develop a method for quick identification of sun-dried and sulfur-fumigated Cimicifugae Rhizoma by Fourier transform infrared spectroscopy (FTIR). METHODS The alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Cimicifugae Rhizoma were analyzed and compared by FTIR combined with second derivative infrared spectroscopy. RESULTS FTIR spectra showed that there were some differences in the positions of infrared absorption peaks and the relative intensities in the alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Cimicifugae Rhizoma, and the second derivative IR spectra clearly enhanced the spectral resolution of their differences. FTIR spectra showed that the new absorption peaks of Cimicifugae Rhizoma appeared and a part of original absorption peaks disappeared after sulfur-fumigation in aqueous extracts, while a lot of new absorption peaks appeared and the intensities of almost all absorption peaks significantly decreased after sulfur-fumigation in alcoholic extracts. Second derivative IR spectra showed that both sun-dried and sulfur-fumigated Cimicifugae Rhizoma extracted by water differed significantly from each other ranging from about 3 950 to 3 940 cm(-1), 3 850 to 3 800 cm(-1), 1 800 to 1 750 cm(-1), as well as from 1 400 to 1 350 cm(-1); Differences also existed between sun-dried and sulfur-fumigated Cimicifugae Rhizoma extracted by ethanol ranging from about 3 980 to 3 960 cm(-1), 3 850 to 3 800 cm(-1), and 1 500 to 1 460 cm(-1). CONCLUSION The FTIR method combined with the second derivative IR spectrum can be used to analyze and distinguish sun-dried and sulfur-fumigated Cimicifugae Rhizoma quickly and accurately. The developed method provides an efficient approach for the quality control of Chinese herbal medicines with its simplicity and strong specificity.

Abstract
A study on the kinetics of inhibitory effect of isoferulic acid on the monophenolase and diphenolase activity of mushroom tyrosinase was carried out using enzymological kinetic analysis method in a Na2HPO4-NaH2PO4 buffer solution (pH = 6.8) at 30°C. It was found that isoferulic acid efficiently inhibits both monophenolase and diphenolase activities of mushroom tyrosinase under experimental conditions. Concentrations of isoferulic acid leading to 50% rate inhibition (IC50) on monophenolase and diphenolase activity were calculated to be 0.13 mmol/L and 0.39 mmol/L, respectively, which are much lower than that of arbutin (IC50 = 5.3 mmol/L for diphenolase activity). The presence of isoferulic acid also prolongs the lag period in the oxidation process of l-tyrosine via tyrosinase-a 4.3-min lagging was observed with the presence of 0.20 mmol/L isoferulic acid-compared to a 1.1-min lagging in the absence of isoferulic acid. The Lineweaver-Burk plot demonstrates a competitive behavior of isoferulic acid in the tyrosinase oxidation of l-3,4-dihydroxyphenylalanine, with maximum reaction rate (vm) and inhibition constant (KI) at 64.5 µM/min and 0.11 mmol/L, respectively.

Abstract
OBJECTIVES The aim of this study was to investigate the impact of commercially available, over-the-counter herbal supplements (St John's wort, black cohosh and ginger root extract) on the metabolic activation of tamoxifen and irinotecan. METHODS Co-incubation of each drug and supplement combination over a range of concentrations was conducted in human liver microsomes and the decrease in the rate of active metabolite formation was monitored using high-performance liquid chromatography tandem mass spectrometry. Data was analysed using non-linear regression analysis and Dixon plots to determine the dominant mechanism of inhibition and to estimate the Ki and IC50 values of the commercial supplements. KEY FINDINGS The data suggest that black cohosh was the strongest inhibitor tested in this study for both CYP450 and carboxyesterase mediated biotransformation of tamoxifen and irinotecan, respectively, to their active metabolites. St John's wort was a stronger inhibitor compared with ginger root extract for tamoxifen (CYP mediated pathway), while ginger root extract was a stronger inhibitor compared with St John's wort for the carboxyesterase mediated pathway. CONCLUSIONS Commercially available supplements are widely used by patients and their potential impact on the efficacy of the chemotherapy is often unknown. The clinical significance of these results needs to be evaluated in a comprehensive clinical trial.

Abstract
To establish a fingerprint for Cimicifugae Rhizoma from different producing areas. Column kromasil (4.6 mm x 250 mm, 5 microm) was employed with acetonitrile-0.1% formic acid solution as the mobile phase for gradient elution. The flow rate was 1.0 mL x min(-1), the detection wavelength was 254 nm. Twenty chromatographic peaks were extracted as the common peaks of fingerprint, and 21 batches of samples were compared and classified with such methods as similarity evaluation, cluster analysis and principle component analysis. The results showed 12 common peaks and three categories of samples. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of Cimicifugae Rhizoma from different producing areas.

Abstract
BACKGROUND Root extracts of Cimicifuga racemosa (L.) Nutt. have been successfully used in the treatment of climacteric complaints. METHOD In this observational study, Cimicifuga racemosa (CR) extract Ze 450 was studied in 442 unselected ambulatory female outpatients with menopausal complaints under daily practice conditions. Physicians were suggested to treat patients for the first 3 months with 13 mg/d CR (high dose, HD) and to continue over additional 6 months either with this treatment or to switch to 6.5mg/d CR (low dose, LD). The choice of treatment and its dose, however, was fully at the discretion of the physician. RESULTS After 3-months treatment with HD, symptom severity (Kupperman Menopause Index, KMI) decreased significantly (p<0.001) from baseline values. Continuation of treatment with HD or LD decreased total KMI and its sub-item scores further (HD, LD: p<0.001). However, more patients (84.9%) responded to HD than to LD (78.4%) and showed an improvement of symptoms (p=0.011). CONCLUSION This observational study demonstrated that treatment with CR in unselected patients with climacteric complaints under the conditions of daily practice resulted in a significant improvement of menopausal symptoms assessed by the total KMI score and its sub-item scores with an effect size similar to that in a previous randomized, controlled clinical trial.

Abstract
Nine new triterpene derivatives, yunnanterpenes A-F (1-6), 15,16-seco-cimiterpenes A and B (7, 8), and cimilactone C (9), and 15 known analogues (10-24) were isolated from the aerial parts of Cimicifuga yunnanensis. The new structures were established using a combination of MS, NMR, and single-crystal X-ray diffraction techniques. WT MEFs (wild-type mouse embryonic fibroblasts) and tumorigenic cell lines p53(-/-)+H-RasV12 and p53(-/-)+p53(N236S)+H-RasV12 were used for evaluating active structures, targeting p53(N236S) (corresponding to p53(N239S) in humans) mutation. Compound 5 showed nonselective activities against these cell lines, with IC50 values of 5.8, 8.6, and 6.0 μM, respectively. Compound 4 exhibited greater selectivity against the p53(-/-)+p53(N236S)+H-RasV12 cells (IC50 5.5 μM) than against the WT MEFs cells (IC50 14.3 μM).

Abstract
Six new 9,19-cycloartane triterpene glycosides, heracleifolinosides A-F (1-6), and one new chromone, norkhelloside (7), were isolated from the rhizome of Cimicifuga heracleifolia, together with 15 known compounds (8-22). The structures of the new compounds were elucidated by means of spectroscopic methods including 2D NMR and mass spectrometry. The extracts of C. heracleifolia and all the isolated compounds were tested for activities against hypoxia and reoxygenation injury in human umbilical vein endothelial cells. Heracleifolinoside B (2) is effectively resistant to hypoxia and reoxygenation-induced human umbilical vein endothelial cell injury, with cell viabilities of 61.95 ± 2.04 %, 77.04 ± 4.44 %, and 83.65 ± 3.29 % at concentrations of 1, 10, and 100 µM, respectively.

Abstract
Twelve new 9,19-cycloartane triterpenes (1-12), together with fourteen known compounds (13-26), were isolated from the roots of Cimicifuga dahurica. Their structures were determined by application of spectroscopic analyses and chemical methods. Biological evaluation of the compounds against human HL-60, SMMC-7721, A549, MCF-7, and SW-480 cell lines indicated that cimigenol-type glycosides (1-3, 19, and 20) showed broad-spectrum and moderate cytotoxicities, with IC50 values ranging from 4.2 to 14.5 µM. Meanwhile, cimigenol-type aglycones (6-8, 15, 16, and 18) exhibited broad-spectrum and week cytotoxicities, having IC50 values around 20 µM. In addition, the key points of the structure-activity relationships of aglycones with a cimigenol skeleton were discussed.

Abstract
Cimicifuga racemosa extracts have long been used to treat female reproductive disorders both in Asia and Europe. Here in this study, we examined the possible estrogen receptor (ER)alpha effects of Cimicifuga heracleifolia var. bifida ethanol extract (C-Ex), which has been used traditionally in Asia, in MCF-7 cells. The activity of C-Ex was characterized in a transient transfection system, using ERa and estrogen-responsive luciferase plasmids in HEK 293 cells and endogenous target genes were studied in MCF-7 cells. C-Ex failed to activate ERalpha and at a concentration of 0.005-0.5 mg/ml as examined by reporter activity. In addition, no statistically significant antiestrogenic activity was observed. However, to our interest, C-Ex enhanced expression of VEGF at 0.5 mg/ml concentration and repressed ERalpha both at the mRNA and protein levels in MCF-7 cells. These results suggested that C-Ex does not activate or inactivate ERalpha in a direct manner, but the extracts may affect factors in ER signal transduction pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cimicifuga foetida L., a traditional Chinese medicine, has been used as an anti-inflammatory, antipyretic and analgesic remedy. The primary active constituents are believed to be present in the triterpene glycoside fraction. MATERIALS AND METHODS To develop an LC-MS/MS assay for four major cimicifugosides [cimicifugoside H-1 (Cim A), 23-epi-26-deoxyactein (Cim B), cimigenolxyloside (Cim C) and 25-O-acetylcimigenoside (Cim D)] obtained from C. foetida L. and apply it to investigate their pharmacokinetic (PK) properties and bioavailabilities through oral administration of C. foetida L. extract (12.5, 25 and 50mg/kg) and single intravenous (i.v.) doses (5mg/kg) of the individual cimicifugosides in rat. PK parameters were estimated by non-compartmental analysis. RESULTS All calibration curves showed excellent linear regressions (all r>0.995) within the range of tested concentrations. The intra- and inter-day variations were <15% in terms of RSD. The molar ratio of Cims A, B, C, and D in the extract was 20.7:1.4:2.9:1. PK parameters for Cims A, B, C, and D following oral administration of the extract were respectively: C(max) 4.05-17.69, 90.93-395.7, 407.1-1180 and 21.56-45.09pmol/mL; T(max) 0.46-1.28, 2.00-4.67, 14.67-19.67 and 8.08-14.27h; absolute oral bioavailability (F) 1.86-6.97%, 26.8-48.5%, 238-319% and 32.9-48%. PK parameters after i.v. administration of individual cimicifugosides were respectively: elimination half-life 1.1, 2.5, 5.7 and 4.2h; clearance 15.7, 0.48, 0.24 and 1.13mL/hkg. CONCLUSIONS Systemic exposure to Cims B, C and D following oral administration of the extract was significantly greater than to Cim A despite the predominance of Cim A in the extract. Significantly different clearance and interconversion from Cim A to Cim C probably accounts for the different exposure to the four cimicifugosides.

Abstract
The aim of this work was to evaluate the effects of therapeutic doses of Cimicifuga racemosa on cardiovascular parameters and on liver lipid metabolism and redox status in an animal model of estrogen deficiency associated with hypertension, a condition that could make the liver more vulnerable to drug-induced injuries. Female Wistar rats were subjected to the surgical procedures of bilateral ovariectomy (OVX) and induction of renovascular hypertension (two-kidneys, one-clip; 2K1C). These animals (OVX + 2K1C) were treated with daily doses of a C. racemosa extract, using a dose that is similar to that recommended to postmenopausal women (0.6 mg/kg), over a period of 15 days. The results were compared to those of untreated OVX + 2K1C, OVX, and control rats. The treatment with C. racemosa caused a significant reduction in blood pressure. In the liver, treatment did not prevent the development of steatosis, and it reduced the mitochondrial and peroxisomal capacity to oxidize octanoyl-CoA compared to the untreated animals. In addition, C. racemosa caused numerous undesirable effects on the liver redox status: it increased the mitochondrial reactive oxygen species generation, an event that was not accompanied by an increase in the activity of superoxide dismutase, and it induced a decrease in peroxisomal catalase activity. Although the reduced glutathione content had not been affected, a phenomenon that probably reflected the restoration of glucose-6-phosphate dehydrogenase activity by C. racemosa, oxidative damage was evidenced by the elevated level of thiobarbituric acid-reactive substances found in the liver of treated animals.

Abstract
PURPOSE Elderly people often develop visceral obesity accompanied by osteoporosis. Visceral adipocytes secrete a number of adipokines and cytokines which augment the development of arteriosclerosis and type 2 diabetes. Bone marrow fat cells also secrete these pro-inflammatory cytokines which stimulate osteoclast and inhibit osteoblast activity. Ovariectomized (ovx) rats also develop general and bone marrow obesity and osteoporosis both of which can be partially prevented by estradiol (E2) and the special extract of Cimicifuga racemosa (CR) BNO 1055. Whether this extract or the thereof isolated triterpene-saponins or polar substances can also prevent bone marrow obesity and thereby the development of osteoporosis was compared with the effects of estradiol (E2). METHODS Rats were ovx and fed with food containing either CR BNO 1055 or its triterpene-saponin or polar constituents or with E2 for 4 weeks. Histomorphometry and STRUT analyses were applied to histological preparations to determine the amount of trabecles, hematopoietic and fat tissue in the bone marrow. RESULTS Ovx rats lost significant amounts of trabecular BMD, surface and nodes while the number of free trabecular ends and fat load in the marrow increased. This was totally prevented by E2 and partially by CR BNO 1055 and the triterpene-saponin but not by the polar fraction. High serum osteocalcin and CrossLaps levels were reduced by E2 and the S-fraction. CONCLUSIONS It is well established that E2 prevents osteoporosis. It is also known that CR BNO 1055 does not contain estrogenic substances. CR BNO 1055 and the triterpene-saponin-fraction reduced the development of osteoporosis most likely by a reduction of the bone marrow fat load and possibly by reducing the secretion of pro-inflammatory cytokines. Hence, the triterpene-saponin-fraction may serve as a basis for a new osteoporosis preventing preparation also in human patients.

Abstract
One new and six known triterpene xylosides were isolated from Cimicifuga racemosa (black cohosh, Actaea racemosa). The structure of a new compound, designated as isocimipodocarpaside (1), was established to be (24S)-3β-hydroxy-24,25-oxiirane-16,23-dione-9,10-seco-9,19-cyclolanost-1(10),7(8),9(11)-trien 3-O-β-d-xylopyranoside, by means of (1)H and (13)C NMR, IR and Raman spectroscopies and Mass Spectrometry. The six known compounds are: 23-epi-26-deoxycimicifugoside (2), 23-epi-26-deoxyactein (3), 25-anhydrocimigenol xyloside (4), 23-O-acetylshengmanol xyloside (5), 25-O-acetylcimigenol xyloside (6) and 3'-O-acetylcimicifugoside H-1 (7). On the basis of NMR data supported by DFT calculations of NMR shielding constants of (2), its structure, previously described as 26-deoxycimicifugoside was corrected and determined as 23-epi-26-deoxycimicifugoside. The (13)C CPMAS NMR spectra of the studied compounds (1)-(7) provided data on their solid-state interactions. The IR and Raman spectra in the CO, CC, and CH stretching vibration regions clearly discriminate different triterpenes found in C. racemosa.
