Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cistanche tubulosa (CT) is the dried fleshy stem with scaly leaves of Cistanche tubiflora (Schenk) Wight, which has the effects of tonifying the kidney-yang, benefiting the vital essence and blood, and moisturizing the intestines and laxatives. There are differences in the activity of CT before and after processing, but the mechanism of processing is not clear. AIM OF THE STUDY The study aimed to compare the strength of action of CT before and after yellow-wine processing in the treatment of constipation and kidney yang deficiency and to identify the active ingredients responsible for the differences in activity before and after yellow-wine processing. MATERIALS AND METHODS This study established the fingerprints of CT and PCT using HPLC to identify their shared components. Then efficacy of KYDS and FC were carried out to compare the differences between CT and PCT in terms of efficacy. Next, this study established the spectrum-effect relationship between the shared chemical components and the medical effects of CT and PCT using the gray correlation analysis and entropy methods. Ultimately, the activity of the analyzed chemical components was verified using the zebrafish model. RESULTS CT was more effective than PCT in promoting intestinal peristalsis, regulating gastrointestinal hormone levels, and thus treating FC. PCT was more effective than CT in improving the level of hormone indexes of the hypothalamus-pituitary-target gland axis, replenishing blood, and enhancing immunity. Through the analysis of the spectrum-effect relationship, it was finally found that 5, 6, 12 (tubuloside A), and 13 (isoacteoside) might be more closely related to the activity of tonifying kidney yang, and peaks 9, 10, and 11 (acteoside) are more closely associated with the treatment of constipation, and peaks 3 (salidroside), 4, 1, 2 (geniposidic acid), and 8 (echinacoside) were associated with both kidney yang tonic and treatment of constipation. At the same time, an activity verification experiment showed that echinacoside, geniposidic acid, and salidroside were effective in the treatment of FC and KYDS, while acteoside was very effective in the treatment of FC, and tubuloside A was significant in supplementing the blood, which validated the spectrum-effect relationship analysis. CONCLUSION This study proved that the raw CT had a better laxative effect, while the yellow-wine processed CT had a better kidney-yang tonic effect; moreover, spectrum-effect relationships were established to analyze the chemical components leading to changes in the activity of CT before and after yellow-wine processing.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ischemic stroke (IS) has both high morbidity and mortality. Previous research conducted by our group demonstrated that the bioactive ingredients of the traditional medicinal and edible plant Cistanche tubulosa (Schenk) Wight (CT) have various pharmacological effects in treating nervous system diseases. However, the effect of CT on the blood-brain barrier (BBB) after IS are still unknown. AIM OF THE STUDY This study aimed to identify CT's curative effect on IS and explore its underlying mechanism. MATERIALS AND METHODS IS injury was established in a rat model of middle cerebral artery occlusion (MCAO). Gavage administration of CT at dosages of 50, 100, and 200 mg/kg/day was carried out for seven consecutive days. Network pharmacology was used for predicting the pathways and potential targets of CT against IS, and subsequent studies confirmed the relevant targets. RESULTS According to the results, both neurological dysfunction and BBB disruption were exacerbated in the MCAO group. Moreover, CT improved BBB integrity and neurological function and protected against cerebral ischemia injury. Network pharmacology revealed that IS might involve neuroinflammation mediated by microglia. Extensive follow-up studies verified that MCAO caused IS by stimulating the production of inflammatory factors and microglial infiltration. CT was found to influence neuroinflammation via microglial M1-M2 polarization. CONCLUSION These findings suggested that CT may regulate microglia-mediated neuroinflammation by reducing MCAO-induced IS. The results provide theoretical and experimental evidence for the efficacy of CT therapy and novel concepts for the prevention and treatment of cerebral ischemic injuries.

Abstract
Cistanche tubulosa (CT), a well-known TCM, has always been processed with rice wine for the treatment of kidney-yang deficiency syndrome (KYDS) since time immemorial. In order to explore the effect of processing on the efficacy and metabolites of CT in vivo, a comprehensive method using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) was established for the analysis of the altered endogenous metabolites in response to the intervention of the raw and processed CT in KYDS model, and the metabolites of the absorbed compounds in rats after gastric perfusion. It was showed that CT could improve KYDS, and the effect of processed product was more significant. A total of 47 differential metabolites were identified in urine. Pathway analysis proved that purine metabolism, alanine, aspartate and glutamate metabolism, and citrate cycle were the main pathways. Furthermore, 53 prototypes and 48 metabolites have been detected in rats. This was the first systematic research focus on the metabolites of raw and processed CT in vivo, which could provide a scientific basis for explaining the increasing efficiency of the processed CT. Moreover, it provides a valuable strategy for analyzing the chemical components and metabolites of other traditional Chinese medicine prescriptions.

Abstract
Background The dried stem of Cistanche, is a famous Chinese traditional medicine. The main active pharmacodynamic components are phenylethanol glycosides (PhGs). Cistanche tubulosa produces higher level of PhGs in its stems than that of Cistanche deserticola. However, the key genes in the PhGs biosynthesis pathway is not clear in C. tubulosa. Results In this study, we performed the full-length transcriptome sequencing and gene expression profiling of C. tubulosa using PacBio combined with BGISEQ-500 RNA-seq technology. Totally, 237,772 unique transcripts were obtained, ranging from 199 bp to 31,857 bp. Among the unique transcripts, 188,135 (79.12%) transcripts were annotated. Interestingly, 1080 transcripts were annotated as 22 enzymes related to PhGs biosynthesis. We measured the content of echinacoside, acteoside and total PhGs at two development stages, and found that the content of PhGs was 46.74% of dry matter in young fleshy stem (YS1) and then decreased to 31.22% at the harvest stage (HS2). To compare with YS1, 13,631 genes were up-regulated, and 15,521 genes were down regulated in HS2. Many differentially expressed genes (DEGs) were identified to be involved in phenylpropanoid biosynthesis pathway, phenylalanine metabolism pathway, and tyrosine metabolism pathway. Conclusions This is the first report of transcriptome study of C. tubulosa which provided the foundation for understanding of PhGs biosynthesis. Based on these results, we proposed a potential model for PhGs biosynthesis in C. tubulosa.

Abstract
INTRODUCTION As a major public health issue, the skin cancer is a leading reason of death and has resulted in significant financial and human losses globally. Numerous environmental and internal variables may both drive and exacerbate the pathophysiology of the skin cancer. Marine herbs and animals, including marine sponges, cucumbers, and squirts, have been shown to have cytotoxic consequences on cancerous cells in prior research. PURPOSE melanoma mitochondria obtained from skin of melanoma animal model are studied in this research to see whether extracts from Cistanche tubulosa, a plant endemic to the northern coasts of the Persian Gulf, has a cytotoxic impact on them. MATERIAL AND METHOD In this study, the mitochondria isolated from melanoma cells via differential centrifugation and treated with various concentrations (1250, 2500 and 5000 µg/ml) of methanolic extract of C. tubulosa. Then MTT, ROS, MMP decline, mitochondrial swelling, cytochrome c release and flow cytometry assays were performed on them. RESULTS The results of MTT assay showed that the IC50 of C. tubulosa extract is 2500 μg/ml and C. tubulosa extract induced a selectively significant (P < 0.05) concentration-dependent decrease in the SDH activity in cancerous skin mitochondria. The ROS results also showed that all concentrations of C. tubulosa extracts significantly increased ROS production, MMP decline and the release of cytochrome c in cancer groups mitochondria. The swelling of mitochondria isolated from the cancer group was significantly increased compared to the control group. In addition, the results of apoptosis assay showed that addition of root extract of Cistanche tubulosa on melanoma cells increased apoptosis, while it had no effect on control non tumor cells. DISCUSSION AND CONCLUSION Based on these results, the presence of potentially bioactive compounds in C. tubulosa make this Persian Gulf coastal herb a strong candidate for further molecular studies and clinical research in the field of melanoma cancer therapy.

Abstract
BACKGROUND Cistanche tubulosa is a tonic in traditional Chinese medicines and has a broad spectrum of biological activity, including anti-inflammatory. However, the anti-inflammatory major constituents of C. tubulosa and their underlying mechanisms are still unknown. OBJECTIVE The aim of the current study was to explore the separation and structural characterization of lignan glycosides from C. tubulosa (Schenk) Wight., their anti-inflammatory activity and the underlying mechanism. MATERIALS AND METHODS Fractionation and isolation of the 85% EtOH extract of C. tubulosa (Schenk) Wight. were carried out and the primary ingredients lignan glycosides (1-6) were structurally characterized. CCK8 methods were used to evaluate the cytotoxic effect of lignan glycosides (1-6). Effects of lignan glycosides (1-6) on NO production in LPS/IFN-γ-induced RAW264.7 macrophages cells were measured using Griess reagent by reaction with nitrite. The mRNA expression levels of iNOS, COX-2, IL-1β, IL-6, TNF-a, and TGF-β treated RAW264.7 cells with various concentrations (0, 25 and 50 μg/ml) of lignan glycosides (1, 4) in the presence of LPS (10 ng/ml) and IFN-γ (20 ng/ml) for 24 h were analyzed by quantitative RT-PCR. Also, the protein expressions of iNOS, COX-2, PI3K, AKT, p-AKT and β -actin were determined using Western blot analysis. A molecular docking study was performed to investigate the interactions between the lignan glycosides and the PI3K using Autodock vina 1.1.2 package. RESULTS Six lignan glycosides (1-6) were isolated from stems of C. tubulosa. Among them, (+)- pinoresinol-4-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside (5) and eleutheroside E (6) were firstly isolated from C. tubulosa. Of these lignans, 1 and 4 exhibited pronounced inhibitions on NO production with the values of 33.63 ± 4.78 and 39.28 ± 5.52 % at 50 μg/ml, respectively. Additionally, LPS/IFN-γ-induced expression of inducible Nitric Oxide Synthase (iNOS), Cyclooxygenase-2 (COX-2), Interleukin-1β (IL-1β), IL-6, and Tumor Necrosis Factor-a (TNF-a) was significantly suppressed by pre-treatment of 1 and 4 in a dose-dependent manner. While 1 and 4 increased the mRNA levels of anti-inflammatory cytokines (TGF-β). Furthermore, 1 and 4 significantly inhibited the protein levels of PI3K and p-AKT in a dose-dependent manner. CONCLUSION Taken together, these results suggest that 1 and 4 play an important role in the attenuation of LPS/IFN-γ-induced inflammatory responses in RAW264.7 cells and that the mechanisms involve down-regulation of the PI3K/AKT pathway.

Abstract
UDP-glycosyltransferases (UGTs) are an important and functionally diverse family of enzymes involved in secondary metabolite biosynthesis. Coumarin is one of the most common skeletons of natural products with candidate pharmacological activities. However, to date, many reported GTs from plants mainly recognized flavonoids as sugar acceptors. Only limited GTs could catalyze the glycosylation of coumarins. In this study, a new UGT was cloned from Cistanche tubulosa, a valuable traditional tonic Chinese herb, which is abundant with diverse glycosides such as phenylethanoid glycosides, lignan glycosides, and iridoid glycosides. Sequence alignment and phylogenetic analysis showed that CtUGT1 is phylogenetically distant from most of the reported flavonoid UGTs and adjacent to phenylpropanoid UGTs. Extensive in vitro enzyme assays found that although CtUGT1 was not involved in the biosynthesis of bioactive glycosides in C. tubulosa, it could catalyze the glucosylation of coumarins umbelliferone 1, esculetine 2, and hymecromone 3 in considerable yield. The glycosylated products were identified by comparison with the reference standards or NMR spectroscopy, and the results indicated that CtUGT1 can regiospecifically catalyze the glucosylation of hydroxyl coumarins at the C7-OH position. The key residues that determined CtUGT1's activity were further discussed based on homology modeling and molecular docking analyses. Combined with site-directed mutagenesis results, it was found that H19 played an irreplaceable role as the crucial catalysis basis. CtUGT1 could be used in the enzymatic preparation of bioactive coumarin glycosides.

Abstract
BACKGROUND As the most frequently used kidney-yang tonifying herb in traditional Chinese medicine, dried succulent stems of Cistanche tubulosa (Schenk) Wight (CT) have been shown to be effective in the treatment of depression. However, the antidepressant components and their underlying mechanism remain unclear. PURPOSE To explore the active components of CT against depression, as well as the potential mechanisms. STUDY DESIGN AND METHODS Behavioral despair tests were used to assess the antidepressant activities of polysaccharides, oligosaccharides and different glycoside-enriched fractions separated from CT, as well as the typical gut microbiota metabolites including 3-hydroxyphenylpropionic acid (3-HPP) and hydroxytyrosol (HT). Furthermore, the effects of bioactive fractions and metabolites on chronic unpredictable mild stress (CUMS) model were explored with multiple pharmacodynamics and biochemical analyses. Changes in colonic histology and the intestinal barrier were observed by staining and immunohistochemical analysis. Gut microbial features and tryptophan-kynurenine metabolism were explored using 16S rRNA sequencing and western-blotting, respectively. RESULTS Total glycosides (TG) dramatically alleviated depression-like behaviors compared to different separated fractions, reflecting in the synergistic effects of phenylethanoid and iridoid glycosides on the hyperactivation of the hypothalamic-pituitary-adrenal (HPA) axis, severe neuro- and peripheral inflammation, and deficiencies in 5-hydroxytryptamine (5-HT) and brain-derived neurotrophic factor in the hippocampus. Moreover, TG mitigated low-grade inflammation in the colon and intestinal barrier disruption, and the abundances of several bacterial genera highly correlated with the HPA axis and inflammation in CUMS rats. Consistently, the expression of indoleamine 2, 3-dioxygenase 1 (IDO1) in the colon was significantly reduced after TG administration, accompanied by the suppression of tryptophan-kynurenine metabolism. On the other hand, HT also exerted a marked antidepressant effect by ameliorating HPA axis function, pro-inflammatory cytokine release, and tryptophan-kynurenine metabolism, while it was unable to largely adjust the disordered gut microbiota in the same manner as TG. Surprisingly, superior to fluoxetine, TG and HT could further improve dysfunction of the hypothalamic-pituitary-gonadal axis and abnormal cyclic nucleotide metabolism. CONCLUSION TG are primarily responsible for the antidepressant activity of CT; its effect might be achieved through the bidirectional interaction of the phytochemicals and gut microbiota, and reflect the advantage of CT in the treatment of depression.

Abstract
In an aging society, preventing dysfunction and restoring function of the locomotive organs are necessary for long-term quality of life. Few interventional studies have investigated supplementation for locomotive syndrome. Additionally, very few interventional clinical studies on locomotive syndrome have been performed as placebo-controlled, randomized, double-blind studies. We previously found that the administration of 30% ethanolic extract of Cistanche tubulosa improved walking ability in a cast-immobilized skeletal muscle atrophy mouse model. Therefore, we conducted a clinical study to evaluate the effects of C. tubulosa (CT) extract on the locomotive syndrome. Twenty-six subjects with pre-symptomatic or mild locomotive syndrome completed all tests and were analyzed in the study. Analyses of muscle mass and physical activity were performed based on the full analysis set. Intake of CT extract for 12 weeks increased step width (two-step test) and gait speed (5 m walking test) in patients over 60 years old compared with those in a placebo control (p = 0.046). In contrast, the skeletal muscle mass of the body trunk and limbs was unchanged following administration of CT extract. Adverse effects were evaluated by blood tests; no obvious adverse events were observed following the intake of CT extract. In conclusion, this placebo-controlled, randomized, double-blind study demonstrated that treatment with CT extract significantly prevented a decline in walking ability without any notable adverse effects in patients with locomotive syndrome.

Abstract
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on water extract of Cistanche tubulosa stems as a novel food (NF) for its use in food supplements (FS) and foods for special medical purposes (FSMP). The target population is the general adult population excluding pregnant and lactating women. The applicant proposes a maximum daily intake of 2 g for FS and a maximum use level of 10% in FSMP. The characteristic components of the extract are phenylethanoid glycosides (at least 70% of the NF), in particular, echinacoside (25-45% of the NF). The NF has been authorised as a prescription drug in China in 2005 for the treatment of vascular dementia. The Panel notes that an integrated analysis of three studies covering 1,076 patients with vascular dementia treated with the proposed NF at a daily dose of 1,800 mg, reported that 12 adverse events (AEs) were classified to be 'definitely', 'probably' or 'possibly related' to the exposure to the NF. Two of these AE were classified as severe (cerebral haemorrhage and epilepsy). The Panel considers that the reported AEs raise safety concerns. The Panel also notes the limitations of the provided toxicological studies, in particular the non-compliance with the EFSA approach on the genotoxicity testing strategy and the non-compliance with good laboratory practice (GLP) and the respective OECD Guidance documents of the repeated dose toxicity studies. In view of the AEs in the human studies, the Panel considers that additional toxicological studies, following testing guidelines would not be able to overcome the concerns raised from the human studies. The Panel concludes that the safety of the NF has not been established.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cistanche tubulosa is a precious traditional Chinese medicine that has been widely used in the treatment of osteoporosis and Alzheimer's disease. Echinacoside and acteoside are the main active constituents in Cistanche tubulosa that have the pharmacological activities with research value. It has been reported that echinacoside and acteoside could improve the learning and memory ability, promote the proliferation and differentiation of osteoblast. AIM OF STUDY Echinacoside and acteoside from Cistanche tubulosa have shown significant activities of anti-osteoporosis and anti-Alzheimer's disease, while these effects have not been studied concurrently in a rat model. The aim of this study was to establish and verify the model of osteoporosis combined with Alzheimer's disease in rat, and to investigate the double effects of echinacoside and acteoside on this concurrent model. MATERIALS AND METHODS Three model groups of ovariectomy (OVX), sham surgery with D-galactose and AlCl3 (D), ovariectomy with D-galactose and AlCl3 (OVX + D) were set at the same time. The rats in drug treatment groups were ovariectomized. While conducting the intraperitoneal injection of D-galactose and intragastric administration of AlCl3 in the rats of drug treatment groups, the rats were orally administered echinacoside (90 mg/kg/d), acteoside (90 mg/kg/d) and the positive control drugs of estradiol valerate (0.6 mg/kg/d), donepezil HCl (0.8 mg/kg/d), respectively. After the drug treatment of 8 weeks, Morris Water Maze (MWM) test for 6 days was firstly performed. The rats were then sacrificed to harvest the blood, uteri, femora, tibiae and brain tissues. The serum was used for biochemical tests. The uteri were used for histomorphometry. The right femora were used for Micro-CT and histomorphometry, respectively. The right tibiae were used for biomechanical test. The hippocampus collected on ice box was used for biochemical tests. The brain collected by perfusion was used for histomorphometry. RESULTS Compared with Sham group, OVX + D group could significantly reduce the learning and memory ability by causing oxidative damage, impairing neurons in hippocampus and affecting the hydrolysis and synthesis of acetylcholine. Meanwhile, the activities of BALP and TRAP in OVX + D group increased significantly (P < 0.001) as compared to Sham group. In addition, compared with Sham group, the mean bone mineral density obviously decreased (P < 0.05), the trabecular bone mass and microarchitecture were also destroyed significantly in OVX + D group. Furthermore, the maximum load and maximum stress significantly reduced (P < 0.01) and the energy absorption also decreased greatly as compared to Sham group. After administrated with echinacoside and acteoside, the typical pathological features of osteoporosis and Alzheimer's disease were ameliorated. CONCLUSIONS The model of osteoporosis combined with Alzheimer's disease in rat was feasible and successfully established. Echinacoside and acteoside also showed some significant effects on this concurrent model, and they could be potential candidates from Cistanche tubulosa with double effects for further study.

Abstract
Extensive photosynthetic gene loss and rapid evolutionary rate occur in the plastomes of parasitic plants. The holoparasitic plant Cistanche tubulosa of Orobanchaceae is an important medicinal resources that are distributed in arid areas. In this study, the complete plastome of C. tubulosa has been sequenced, assembled and analyzed. The total plastome of C. tubulosa was 75,375 bp in length, consisting of a pair of inverted repeats (IRs, 6,593 bp), a large single-copy region (LSC, 32,470 bp) and a small single-copy region (SSC, 29,719 bp). It contained 24 intact protein coding genes, nine pseudogenes, and 44 missing genes. In addition, all the protein-coding genes, which were related to photosynthesis and energy production, were pseudogenised or lost. Four rRNA genes and 24 tRNA genes were intact meanwhile five tRNA genes were missing. Phylogenetic tree indicated that C. tubulosa was closely related to C. phelypaea. Our results may improve understanding of the plastome organization, classification, and evolution of parasitic plants.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Osteoporosis (OP) and Alzheimer's disease (AD) are common geriatric concurrent diseases, and many studies indicate the connection of their pathogenesis. Cistanche tubulosa (Schenk) Wight (CT) is a widely used traditional Chinese medicine and has been extensively applied to treat OP and AD, respectively. However, the active ingredients for both concurrent diseases simultaneously and underlying mechanisms are limited. AIM OF STUDY This work aimed at establishing an effective and reliable network screening method to find dual-effects compounds in CT that can protect AD and OP concurrently. And it will provide new perspectives of the link between OP and AD on molecular mechanisms. MATERIAL AND METHODS The dual-effects of CT were systematically analyzed with integrating multiple databases and extensive analysis at a network pharmacology level. Classified drug-target interaction network was constructed to reveal differences in effects between different types of compounds. To prove the effectiveness of this network, some compounds were selected to verify in Pre-induced OP model and AlCl3-induced AD model of zebrafish according to the topological parameters. RESULTS 22 dual-effects active ingredients in CT were initially screened out via network pharmacology with a closely connection with 81 OP and AD-related targets. Classified network analysis found the better bioactivities of phenylethanoid glycosides and flavonoids. The dual-effects of four selected compounds demonstrated that the network is reasonable and effective, suggesting the dual-effects of the remaining 18 compounds. Moreover, we identified 9 putative targets and two pathways that were significantly related to OP and AD. CONCLUSIONS We successfully identified 22 dual-effects active components in CT. This systematic screening strategy provided a new protocol to objectively discover multi-effects compounds of traditional Chinese medicine, and even a macroscopic perspective that will improve our understanding of the link between OP and AD on molecular mechanisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cistanche tubulosa (Schenk) R. Wight has been used frequently in traditional folk medicine for treatment of male sexual dysfunction (MSD). Phenylethanol glycosides, the main components of C. tubulosa, possess a variety of pharmacological activities due to their multiple properties. However, the underlying mechanism by which phenylethanol glycosides from C. tubulosa (CPhGs) regulates testicular steroids has not been elucidated to date. AIM OF THE STUDY This study is to determine whether CPhGs promotes the reproductive functions of mice through CYP450-3β-HSD pathway of testosterone synthesis. MATERIALS AND METHODS The major compositions of C. tubulosa (CPhGs) were quantified by high performance liquid chromatography (HPLC). The model of reproductive injury in mice were induced by injection of hydrocortisone (HCT). Different doses of CPhGs (72, 145 and 289 mg/kg) and testosterone propionate (TP, positive control drug) were administrated intragastrically for 14 d. The reproductive functions (erectile incubation period, capture and ejaculation incubation period, number of captures and ejaculations) and organ weights (testicle, epididymis, seminal vesicle and penis) were then determined. The levels of luteinizing hormone and testosterone in serum were quantified by radioimmunoassay. The key enzymes in testosterone synthesis pathways such as steroidogenic acute regulatory protein (StAR), cytochrome P450 cholesterol side chain cleavage enzyme (P450scc/CYP11A1) and 3β-hydroxysteroid dehydrogenase (3β-HSD) in the testis were assessed by immunofluorescence (IF) staining or/and Western blot (WB) analysis. RESULTS The results illustrated that the low dose of CPhGs (72 mg/kg) had no significant protective effect against the reproductive injury caused by HCT, while the moderate dose of CPhGs (145 mg/kg) improved the damaged reproductive ability and the declined levels of luteinizing hormone and testosterone in the model mice (P < 0.001, P < 0.05, respectively). In particular, high dose of CPhGs (289 mg/kg) was most effective in improving HCT-induced changes in body weight (P < 0.01), reducing the incubation period of the erectile (P < 0.001), capture (P < 0.05) and ejaculation (P < 0.01), and increasing the number of captures and ejaculations (P < 0.01, P < 0.05, respectively). The weights of testcle, epididymis, seminal vesicle and penis (P < 0.001, P < 0.01, P < 0.01, P < 0.001, respectively) were improved by high dose of CPhGs. The levels of testosterone and its upstream luteinizing hormone were up-regulated by high dose of CPhGs (P < 0.001). Meanwhile, the expressions of the key steroidogenic enzymes including CYP11A1 and 3β-HSD were significantly up-regulated after CPhGs treatment (P < 0.001), demonstrated that CPhGs exerted the effect through enhancing testosterone biosynthesis via CYP450-3β-HSD pathway. CONCLUSIONS CPhGs could significantly protect against HCT-induced deleterious reproductive dysfunction and testis injury. The protective effects were exerted by up-regulating synthesis of testosterone via the CYP450-3β-HSD pathway in Leydig cells.

Abstract
Acteoside (ACT) is the main component of phenylethanoid glycosides in Cistanche tubulosa, and it is extremely desirable for obtaining high purification of ACT by molecularly imprinted polymers (MIPs) from their extracts. In this study, MIPs were designed and synthetized to adsorb selectively the ACT in C. tubulosa. The effects of different functional monomers, cross-linkers, and solvents of MIPs were investigated. MIPs were studied in terms of static adsorption experiments, dynamic adsorption experiments, and selectivity experiments. The optimal functional monomer, cross-linking agent, and solvent are 4-vinylpyridine, ethylene glycol dimethylacrylate, and the mixed solvent (acetonitrile and N,N-dimethylformamide, 1:1.5, v/v), respectively. Under the optimal conditions, the synthesized MIP1 has a high adsorption performance for ACT. The adsorption capacity of MIP1 to ACT reached 112.60 mg/g, and the separation factor of ACT/echinacoside was 4.68. Because the molecularly imprinted cavities of MIP1 resulted from template molecules of ACT, it enables MIP1 to recognize selectively ACT. Moreover, the N–H groups on MIP1 can form hydrogen bonds with the hydroxyl groups on the ACT; this improves the separation factor of MIP1. The dynamic adsorption of ACT accorded with the quasi-second-order kinetics; it indicated that the adsorption process of MIP1 is the process of chemical adsorption to ACT. MIPs can be applied as a potential adsorption material to purify the active ingredients of herbal medicines.

Abstract
PhGs are the major active compounds of Cistanche tubulosa, and it is extremely desirable for obtaining high purification of PhGs by adsorption from their extracts. To explore highly efficient adsorption of PhGs, a novel adsorption material for the efficient separation and purification of phenylethanoid glycosides (PhGs) from Cistanche tubulosa was explored. The three mesoporous carbons of ordered mesoporous carbon (CMK-3), disordered mesoporous carbon (DMC), and three-dimensional cubic mesoporous carbon (CMK-8) were compared for adsorption of PhGs. Meanwhile, adsorption isotherms, adsorption kinetics, and the optimization of adsorption conditions were investigated. The results indicated that CMK-3 showed the highest adsorption capacity of 358.09 ± 4.13 mg/g due to its high specific surface area, large pore volume and oxygen-containing functional groups. The experimental data can be accurately described using the Langmuir model and pseudo-second-order model. The intra-particle diffusion model suggested that the rate-limiting steps of adsorption were intra-particle diffusion.

Abstract
To investigate the inhibitory effects and mechanism of Cistanche tubulosa ethanol extract( CTEE) against oxygen-glucose deprivation/reperfusion( OGD/R)-induced PC12 cells neuronal injury. In this study,OGD/R-induced PC12 cells were used to explore the neuroprotective effects of CTEE( 12. 5,25,50 mg·L-1) by detecting cell viability with MTT assay,apoptosis with AO/EB and Hoechst 33258,mitochondrial membrane potential changes with JC-1 staining,mitochondrial oxidative stress with MitoSOX staining,as well as the apoptosis-related protein expression( PARP,cleaved PARP,caspase-3,cleaved caspase-3,Bax,Bcl-2) with Western blot. RESULTS:: showed that CTEE effectively protected OGD/R-induced neuronal injury and increased the survival rate of PC12 cells.AO/EB and Hoechst 33258 staining showed that CTEE could effectively inhibit apoptosis. Moreover,JC-1 and MitoSOX staining results showed that CTEE decreased mitochondrial stress and mitochondrial membrane potential imbalance in PC12 cells in a concentration-dependent manner. Meanwhile,CTEE could obviously suppress the activation of key proteins in mitochondrial apoptosis pathway such as caspase-3 and PARP,and significantly inhibit the rise of Bax and down-regulation of Bcl-2. In conclusion,CTEE has obvious protective effects on OGD/R-induced PC12 cells neuronal injury,potentially via inhibiting mitochondrial oxidative stress and apoptosis-related signaling pathway.

Abstract
An Orobanchaceae plant Cistanche tubulosa (SCHENK) WIGHT (Kanka-nikujuyou in Japanese), which is one of the authorized plant resources as Cistanches Herba in both Japanese and Chinese Pharmacopoeias, is a perennial parasitic plant growing on roots of sand-fixing plants. The stems of C. tubulosa have traditionally been used for treatment of impotence, sterility, lumbago, and body weakness as well as a promoting agent of blood circulation. In recent years, Cistanches Herba has also been widely used as a health food supplement in Japan, China, and Southeast Asian countries. Here we review our recent studies on chemical constituents from the stems of C. tubulosa as well as their bioactivities such as vasorelaxtant, hepatoprotective, and glucose tolerance improving effects.

Abstract
Cistanche tubulosa aqueous extract (CTE) is already used as a botanical prescription drug for treating dementia in China. Our previous studies reported that phenylethanoid glycosides of CTE have anti-Alzheimer's disease (AD) activity by inhibiting amyloid β peptide (Aβ) aggregation and deposition. However, recent studies considered that the phenylethanoid glycosides may be metabolized by intestinal bacteria, because all analysis results showed that the bioavailability of phenylethanoid glycosides is extremely low. In this study we demonstrate how iron chelation plays a crucial role in the Aβ aggregation and deposition inhibition mechanism of phenylethanoid glycosides of CTE. In addition, we further proved phenylethanoid glycosides (1⁻3) could reach brain. Active CTE component and action mechanism confirmation will be a great help for product quality control and bioavailability studies in the future. At the same time, we provide a new analysis method useful in determining phenylethanoid glycosides (1⁻3) in plants, foods, blood, and tissues for chemical fingerprint and pharmacokinetic research.

Abstract
Cistanche tubulosa has various biological functions. In the present study, the antitumor effect of water-soluble phenylethanoid glycosides of C. tubulosa (CTPG-W) on esophageal cancer was investigated. Eca-109 cells were treated with CTPG-W and the cell viability was measured by MTT assay. The apoptosis, cell cycle, mitochondrial membrane potential (Δψm) and reactive oxygen species were analyzed by flow cytometry. The levels of proteins in apoptotic pathways were detected by western blot analysis. It was determined that CTPG-W significantly reduced the viability of Eca-109 cells through the induction of apoptosis and cell cycle arrest. Following CTPG-W treatment, the Δψm of Eca-109 was notably decreased, which is associated with the upregulated levels of B-cell lymphoma-2 (Bcl-2)-associated X and downregulated levels of Bcl-2. Consequently, the levels of cytochrome c and c-Jun NH2-terminal kinase were increased, which upregulated the levels of cleaved-poly (ADP-ribose) polymerase and cleaved-caspase-3, −7 and −9, but not caspase-8. Correspondingly, the levels of reactive oxygen species in Eca-109 cells demonstrated notable changes. These results indicated that CTPG-W induced apoptosis of Eca-109 cells through a mitochondrial-dependent pathway.

Abstract
As a famous tonic medicine, Cistanche tubulosa has been honored as "ginseng of the deserts" for centuries. Aiming to address the resource shortage as well as the wild resource protection towards this herbal medicine, wide cultivation has been achieved in the southern Xinjiang. Herein, in-depth chemome comparison was conducted between cultivated and wild plants using ¹H-NMR spectroscopy that is capable of comprehensively providing qualitative and quantitative information of given complicated matrices. Multivariate statistical analysis was employed to process the dataset as well as to consolidate that the cultivated plants are comparable to those wild ones in term of chemome. ¹H-NMR spectra of both wild and cultivated plants were acquired in parallel after extraction. Following direct overlaying, great similarity occurred between these two groups. A total of 28 compounds were tentatively identified by referring to authentic compounds together with those available databases, such as HMDB and BMRB. Following principal component analysis, none significant difference was observed between wild and cultivated groups. Above all, from the viewpoint of chemical profile, the cultivated plants were almost equal to the wild plants; therefore, the cultivated plants are able to take the load of wild plants in clinical usage. Moreover, ¹H-NMR spectroscopy is a promising tool for chemical profiling traditional Chinese medicines because of the potential towards simultaneously exhibiting both quantitative and qualitative information for complicated matrices.

Abstract
BACKGROUND Cistanche tubulosa (Schenk) R. Wight is a traditional Chinese medicine that parasitizes the roots of the Tamarix plant and has been used to treat male impotence, sterility, body weakness, and as a tonic. However, its antitumor effect on hepatocellular carcinoma is still elusive. Here, we investigated the antitumor effect of C. tubulosa phenylethanoid glycosides (CTPG) on H22 hepatocellular carcinoma cells both in vitro and in vivo and its mechanisms. METHODS The morphology, viability, apoptosis, cell cycle and mitochondrial membrane potential (Δψm) of H22 cells were analyzed by inverted microscopy, MTT assay and flow cytometry, respectively. The expression and activation of proteins in apoptosis pathway were detected by Western blot. The in vivo antitumor effect was evaluated in tumor mouse model established using male Kunming mice. RESULTS CTPG treatment significantly suppressed H22 cell growth in a dose- and time-dependent manner, which was correlated with the increased apoptosis and cell cycle arrest at G0/G1 and G2/M phases. Moreover, the chromosomal condensation was observed in CTPG-treated H22 cells. CTPG treatment significantly increased Bax/Bcl-2 ratio, reduced Δψm and enhanced the release of cytochrome c. The levels of cleaved caspase-8 and caspase-9 in both extrinsic and intrinsic signaling pathways were significantly increased that sequentially activated caspase-7 and -3 to cleave PARP. Finally, CTPG inhibited the growth of H22 cells in mice and improved the survival rate of tumor mice. CONCLUSIONS These results suggested that CTPG suppressed H22 cell growth through both extrinsic and intrinsic apoptosis pathways.

Abstract
Growing evidence shows that neuropsychiatric disorders, such as depression, are linked with gut microbiome through the gut–brain axis. Cistanches Herba is well known for the treatment of “kidney-yang” deficiency in traditional Chinese medicine (TCM), and has been used for treatment of neurodegenerative diseases in recent years. In this study, chronic unpredictable stress (CUS)-induced depression model was established to explore the impact of Cistanche tubulosa extract (CTE) on behavioral tests, monoamine neurotransmitters and neurotrophic factors in hippocampus and colon, gut microbiota composition, and short-chain fatty acids (SCFAs) production. Moreover, correlation analysis was used to evaluate the functional relationship between altered gut microbiota, changed neurotransmitters and neurotrophins in hippocampus and colon, and disturbed concentration of SCFAs. CTE significantly improved depression-like behaviors in rats under CUS. Brain level of 5-hydroxytryptamine (5-HT) and brain-derived neurotrophic factor (BDNF) expression in CUS rats were restored by CTE. The relative abundance of gut microbiota and the concentrations of acetate and hexanoic acid could also be modulated by CTE treatment. We further showed that the application of CTE in CUS rats led to strong correlation among disrupted gut microbiota composition, hippocampus neurotransmitter levels, and production of neuroactive metabolite SCFAs. Altogether, these results identify CTE as a potential treatment for depressive symptoms by restoring homeostasis of gut microbiota for microbiota–gut–brain axis disorders, opening new avenues in the field of neuropsychopharmacology.

Abstract
The pharmacological effects of Cistanches Herba, known as "Ginseng of the desert", have been extensively studied. In this study, we aimed to assess the genotoxic and oral toxic effects of the Cistanche tubulosa health food product Memoregain® using in vitro and in vivo tests. Ames tests using five strains of Salmonella typhimurium showed no signs of increased reverse mutation upon exposure to Memoregain® up to a concentration of 5 mg/plate. Exposure of Chinese hamster ovary (CHO-K1) cells to Memoregain® did not increase the frequency of chromosomal aberrations in vitro. Moreover, Memoregain® treatment did not affect the proportions of immature to total erythrocytes or the number of micronuclei in the immature erythrocytes of ICR mice. Additionally, after 28-day repeated oral dose toxicity tests (0, 0.15, 0.3, and 0.5g/kg body weight) in rats, no observable adverse effects were found. These toxicological assessments supported the safety of Memoregain® for human consumption.

Abstract
Quantitative determination of multiple effective components in a given plant usually requires a very large amount of authentic natural products. In this study, we proposed a rapid and non-destructive method for the simultaneous determination of echinacoside, verbascoside, mannitol, sucrose, glucose and fructose in Cistanche tubulosa by near infrared spectroscopy (NIRS). Near infrared diffuse reflectance spectroscopy (DRS) and high performance liquid chromatography (HPLC) were conducted on 116 batches of C. tubulosa samples. The DRS data were processed using standard normal variety (SNV) and multiplicative scatter correction (MSC) methods. Partial least squares regression (PLSR) was utilized to build calibration models for components-of-interest in C. tubulosa. All models were then assessed by calculating the root mean square error of calibration (RMSEC), correlation coefficient of calibration (r). The r values of all six calibration models were determined to be greater than 0.94, suggesting each model is reliable. Therefore, the quantitative NIR models reported in this study can be qualified to accurately quantify the contents of six medicinal components in C. tubulosa.

Abstract
BACKGROUND The aging process, including physical dysfunction and age-related memory impairment (AMI), are considered to be correlated with cumulative oxidative damages and insulin/IGF-1 signaling pathway. PURPOSE The present study was to elucidate the in vivo effects on delaying aging and ameliorating AMI and underlying molecular mechanisms of Cistanche tubulosa (CT), a herb used in traditional Chinese medicine to improve sexual function and treat kidney dysfunction. METHODS The flies, treated and untreated with CT, were observed for lifespan, resistance to oxidative stress with H2O2 or paraquat, starvation assay, cognitive behaviors with T-maze, and transcript levels of target genes with quantitative RT-PCR. RESULTS Administering CT extended the mean and maximum lifespan and increased resistance to oxidative stress in flies. CT supplementation also enhanced memory formation in young flies and suppressed AMI upon aging. Several genes and signaling pathways, including the mechanistic target of rapamycin (mTOR) and Notch networks, have been identified as causing these pharmacological effects and alterations in the gene expression of glutamate receptors. CONCLUSION Our results indicate that CT supplementation may contribute to slowing aging phenotypes and alleviating cognitive behavioral decline in flies, indicating potential applicability for enhancing human health and reducing susceptibility to age-related disorders.

Abstract
Parkinson’s disease (PD) is a neurodegenerative disease with the pathological hallmark of reduced nigrostriatal dopamine. In traditional Chinese medicine (TCM) clinical practice, the nanopowder of Cistanche tubulosa has therapeutic effects on PD. To identify the therapeutic mechanism, this study tested the protective effect of different doses of MPP+-induced toxicity in MES23.5 cells using the MTT assay and in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mice (vehicles). Immunohistochemistry was used to assess cytomorphology and tyrosine hydroxylase (TH) expression. Behavioral tests in vehicles, high performance liquid chromatography (HPLC) tests in dopamine, immunohistochemistry and western blot analysis were used to detect the expression of TH, glial cell line-derived neurotrophic factor (GDNF) and its receptors. Our results demonstrated that the C. tubulosa nanopowder improved the viability of MPP+-treated cells, increased TH expression and reduced the number of apoptotic cells. It also increased Bcl2 protein expression and suppressed Bax protein expression in MPP+-treated cells in a dose-dependent manner. In addition, C. tubulosa nanopowder improved the behavioral deficits in vehicle mice, reduced the stationary duration of swimming, enhanced the ability for spontaneous activity and increased the expression of GDNF, the GDNF family receptor alpha (GFRα1) and Ret in cells of the substantia nigra (SN). Furthermore, the protein expression of GDNF, GFRα1 and Ret increased after treatment with different doses of C. tubulosa nanopowder, with a significant difference between the high-dose and vehicle groups. The protein expression of Bcl2 and Bax were similar in the in vivo and in vitro, which suggested that C. tubulosa nanopowder has anti-apoptotic effects in neurons.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Male infertility has been increasing over the last decades and being a pressing health problem nowadays. Cistanche tubulosa (CT) is a traditional Chinese medicine used to boost male sexual function. Echinacoside (ECH) is one of the major compounds exist in CT and might be a potential agent to protect testis and sperm injury. AIM OF THE STUDY To investigate the mechanisms behind the possible protective effects of CT and ECH against testicular and sperm toxicity. MATERIALS AND METHODS CT was identified by 5.8s gene sequencing. The major compositions (echinacoside and acteoside) of CT were quantified by HPLC method. The adult male Sprague-Dawley rats were exposed to BPA, CT or ECH for 42 consecutive days. The sperm parameters were observed by dark-field microscope; serum hormone levels (FSH, LH and testosterone) were tested by radio immunosorbent; LDH-x activity were evaluated using commercial kits; the expressions of the key steroidogenic enzymes were evaluated by qRT-PCR, heat map, immunofluorescence and western blot. RESULTS The CT and ECH treatments against BPA-induced testicular and sperm toxicity showed that CT and ECH have reversed BPA-induced abnormality in sperm characteristics, testicular structure and normalized serum testosterone. This was concomitant with the increased expression of LDH-x as well as the key steroidogenic enzymes including StAR, CYP11A1, 3β-HSD, 17β-HSD and CYP17A1, suggesting that CT and ECH enhanced testosterone biosynthesis. CONCLUSIONS CT and ECH attenuated poor sperm quality and testicular toxicity in rats through up-regulation steroidogenesis enzymes and ECH is the active compound of CT as a potential natural reproductive agent.

Abstract
Cistanches Herba is a famous traditional Chinese medicine that has been in use for treating kidney deficiency, impotence, female infertility, morbid leucorrhea, profuse metrorrhagia, and senile constipation. With the exception of studies available for a few single active ingredients such as echinacoside, acteoside, and poliumoside, comprehensive and systematic studies on in vivo metabolism of Cistanches Herba are lacking despite its widespread clinical application. There is no comparative study yet on the metabolites resulting from the traditional usage of Cistanche deserticola and C. tubulosa water extract - two species that are recorded in Chinese Pharmacopoeia. This further restricts research on the therapeutic effect of Cistanches Herba to a great extent. In this study, a robust and unbiased UPLC-Q-TOF-MS combined pattern recognition analysis (orthogonal partial least squared discriminant analysis, OPLS-DA) was employed to rapidly screen prototype components and metabolites of C. deserticola and C. tubulosa water extract in rat urine, feces, and serum. A total of 71 metabolites from C. deserticola including 25 prototype components and 46 metabolites, and 45 metabolites from C. tubulosa including 18 prototype components and 27 metabolites were tentatively identified. Out of these, 10 metabolites were characterized for the first time in these two species. Results of this study indicate that phenylethanoid glycosides (PhGs) are mainly metabolized into degradation products in the gastrointestinal tract of rats. The chemical components cistanoside B, C, D, and E exist only in C. deserticola and release methylated hydroxytyrosol (HT) following metabolism. This factor contributes to the difference between metabolites of C. deserticola and C. tubulosa water extract in rats and is responsible for the differential therapeutic effect that these two species of Cistanches Herba have on the same diseases.

Abstract
Cistanche tubulosa is a traditional Chinese herbal medicine widely used for regulating immunity and phenylethanol glycosides (CPhGs) are among the primary components responsible for this activity. Previous studies have indicated the preventive and therapeutic effects of CPhGs on bovine serum albumin (BSA)-induced hepatic fibrosis in rats. The aim of the study was to evaluate the anti-hepatic fibrosis effect of CPhGs and the monomers echinacoside and acteoside by inhibiting hepatic stellate cell (HSC) activation, blocking the conduction of signaling pathways in transforming growth factor-β1 (TGF-β1)/smad, and determine their in vitro hepatoprotective activity. HSC proliferation was obviously inhibited after treatment with CPhGs (100, 50 μg/mL)/echinacoside (500, 250, 125 μg/mL)/acteoside (6, 3 μg/mL), with IC50 values of 119.125, 520.345 and 6.999 μg/mL, respectively, in the MTT assay. Different concentrations of CPhGs/echinacoside/acteoside did not affect the cellular toxicity on HSC according to lactate dehydrogenase (LDH) measurements. Different concentrations of CPhGs/echinacoside/acteoside increased the mRNA level and protein expression of smad7, and decreased the mRNA levels of smad2, smad3 and the protein expression of smad2, phospho-smad2 (p-smad2), smad3, phospho-smad3 (p-smad3) in HSC. In summary, these results demonstrate that CPhGs/echinacoside/acteoside can block the conduction of the signaling pathways in TGF-β1/smad, and inhibit the activation of HSC, suggesting that C. tubulosa may thus be a potential herbal medicine for the treatment of liver fibrosis.

Abstract
Cistanche tubulosa and Laminaria japonica have been reported to have anti-oxidative, anticoagulant, anti-cancer and anti-inflammatory properties. They are expected to be a promising candidates for promoting hair growth and treating dandruff and scalp inflammation as a consequence. In this double-blinded, placebo-controlled clinical trial, we investigated the efficacy of Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) in promoting hair health in patients with mild to moderate patterned hair loss. Using phototrichogram (Folliscope 4.0, LeadM, Seoul, Korea), we compared the density and diameter of hairs in patients receiving a placebo or Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) at baseline, 8 and 16 weeks of the study. In order to determine the efficacy of treatment on dandruff and scalp inflammation, investigator's assessment score and patient's subjective score were also performed. We found a statistically significant increase in the hair density of the test group (n = 45, MK-R7 400 mg) after 16 weeks of consuming the MK-R7 (test group: 23.29 n/cm(2) ± 24.26, control: 10.35 n/cm(2) ± 20.08, p < 0.05). In addition, we found a statistically significant increase in hair diameter in the test group compared to control group at week 16 (test group: 0.018 mm ± 0.015, control: 0.003 mm ± 0.013, p < 0.05). There were also significant outcomes regarding the investigator's visual assessment and patient's subjective score of dandruff and scalp inflammation in the test group compared to those in control group. Based on the results of this clinical study, we conclude that Cistanche tubulosa extract and Laminaria japonica extract complex (MK-R7) are promising substances for promoting health of the scalp and hair.

Abstract
Since scalp hair loss has increased recently even in young people, seriously affecting individual's quality of life, the hair growth-stimulating effects of Laminaria japonica extract (LJE) and Cistanche tubulosa extract (CTE) were investigated. After confirming anagen phase of follicles under shaving, male C57BL/6 mice were dermally applied with 3% Minoxidil or orally administered with the combinations of LJE and CTE for 21 days. Minoxidil promoted the hair regrowth and increased γ-glutamyl transpeptidase (γ-GTP) and alkaline phosphatase (ALP) activities. In addition, Minoxidil up-regulated epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) levels. Co-administration of LJE and CTE at 54 mg/kg LJE plus 162 mg/kg CTE exerted synergistic promoting effects on the hair regrowth, comparable to 3% Minoxidil. LJE preferentially enhanced ALP activity, while CTE increased both γ-GTP and ALP activities as well as EGF and VEGF expressions. In vivo air pouch inflammation model, carrageenan-induced vascular exudation and increased nitric oxide and prostaglandin E2 concentrations in the exudates were synergistically suppressed by co-administration of LJE and CTE. In addition, inflammatory cell infiltration was substantially inhibited by the combinational treatment. The results suggest that combinational oral treatment with LJE and CTE in appropriate doses and ratios prevent hair loss and improve alopecia, which might be in part mediated by their anti-inflammatory activities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The dried succulent stem of Cistanche tubulosa (Schenk) R. Wight is one component of traditional Chinese medicine prescriptions for diabetes. However, there have been no modern scientific reports to confirm this traditional claim for the Cistanche species until now. Thus, we investigated the effects of Cistanche tubulosa on glucose homeostasis and serum lipids in male BKS.Cg-Dock7(m) +/+ Lepr(db)/J (db/db) mice, a model of type 2 diabetes. MATERIALS AND METHODS The verbascoside and echinacoside contents of Cistanche tubulosa powder were evaluated using HPLC. The total phenolic content, polysaccharide content and antioxidant activity of Cistanche tubulosa powder were also evaluated. Then, different doses of Cistanche tubulosa (equivalent to 120.9, 72.6 or 24.2mg verbascoside/kg) were administered orally once daily for 45 days to male db/db mice. Age matched db/+ mice were used as normal controls. Body weight, fasting blood glucose, postprandial blood glucose and insulin tolerance test were measured during the experiment. At the time of sacrifice, blood was collected for measurement of insulin level, the homeostatic model assessment of insulin resistance (HOMA-IR), and total cholesterol, triglyceride, HDL-c, LDL-c and VLDL-c levels; liver and muscle were harvested for measurement of glycogen levels. RESULTS Cistanche tubulosa significantly suppressed the elevated fasting blood glucose and postprandial blood glucose levels, improved insulin resistance and dyslipidemia, and suppressed body weight loss in db/db mice. However, Cistanche tubulosa did not significantly affect serum insulin levels or hepatic and muscle glycogen levels. CONCLUSION This study provides scientific evidence for the traditional use of Cistanche tubulosa to treat diabetes, suggesting that Cistanche tubulosa has the potential for development into a functional food ingredient or drug to prevent hyperglycemia and treat hyperlipidemia.
