Abstract
INTRODUCTION Smilacis Glabrae Rhizoma (SGR) is rich in chemical constituents with a variety of pharmacological activities. However, in-depth research has yet to be conducted on the chemical and pharmacodynamic constituents of SGR. MATERIALS AND METHODS In this study, the chemical constituents of SGR were analyzed using liquid chromatography-mass spectrometry, and the pharmacodynamic compounds responsible for the medicinal effects of SGR were elucidated through a literature review. RESULTS In total, 20 potentially new compounds, including 16 flavonoids (C19, C20, and C27-C40) and four phenylpropanoids (C107, C112, C113, and C118), together with 161 known ones were identified in the ethanol extract of SGR using liquid chromatography-mass spectrometry, and 25 of them were unequivocally identified by comparison with reference compounds. Moreover, 17 known constituents of them were identified in the plants of genus Smilax for the first time, and 16 were identified in the plant Smilax glabra Roxb. for the first time. Of 161 known compounds, 84 constituents (including isomers) have been reported to have 17 types of pharmacological activities, covering all known pharmacological activities of SGR; among these 84 bioactive constituents, six were found in the plants of genus Smilax for the first time and five were found in S. glabra for the first time, which are new bioactive constituents found in the plants of genus Smilax and the plant S. glabra, respectively. CONCLUSION The results provide further information on the chemical composition of SGR, laying the foundation for the elucidation of the pharmacodynamic substances of SGR.

Abstract
This study explored the existence forms(original constituents and metabolites) of Tiantian Capsules, Aloe, and Tiantian Capsules without Aloe in rats for the first time, aiming to clarify the contribution of Aloe to the existence form of Tiantian Capsules. Rats were administrated with corresponding drugs by gavage once a day for seven consecutive days. All urine and feces samples were collected during the seven days of administration, and blood samples were collected 0.5, 1, and 1.5 h after the last administration. UHPLC-Q-TOF-MS was employed to detect and identify the original constituents and metabolites in the samples. A total of 34, 28, and 2 original constituents and 64, 94, and 0 metabolites were identified in the samples of rats administrated with Aloe, Tiantian Capsules, and Tiantian Capsules without Aloe, respectively. The main metabolic reactions were methylation, hydrogenation, hydroxylation, dehydroxylation, glucuronidation, and sulfation. This study clarified for the first time the existence forms and partial metabolic pathways of Aloe, Tiantian Capsules, and Tiantian Capsules without Aloe in rats, laying a foundation for revealing their effective forms. The findings are of great significance to the research on the functioning mechanism and quality control of Aloe and Tiantian Capsules.

Abstract
Objective: To analyze the clinical and histopathological features of patients with chronic hepatitis B (CHB) combined with metabolic-associated fatty liver disease (MAFLD). Methods: Clinical data of 529 cases who had liver biopsies at the First Affiliated Hospital of Zhengzhou University between January 2015 and October 2021 were collected. Among them were 290 cases with CHB, 155 cases with CHB combined with MAFLD, and 84 cases with MAFLD. Three groups of patients clinical data, including general information, biochemical indicators, FibroScan indicators, viral load, and histopathology, were analyzed. A binary logistic regression analysis was used to explore the factors influencing MAFLD in patients with CHB. Results: (1) Age, male status, proportion of hypertension and diabetes, body mass index, fasting blood glucose, γ-glutamyl transpeptidase, low-density lipoprotein, cholesterol, triglycerides, uric acid, creatinine, and the controlled attenuation parameter for hepatic steatosis were higher in CHB combined with MAFLD than in CHB patient groups. In contrast, the high-density lipoprotein, HBeAg positivity rate, viral load level, and liver fibrosis grade (S stage) were lower in CHB patients, and the differences were statistically significant (P < 0.05). (2) Alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transpeptidase, triglycerides, uric acid, creatinine, and the controlled attenuation parameter for hepatic steatosis in CHB combined with the MAFLD were lower than those in MAFLD patient groups, while high-density lipoprotein was higher than that of MAFLD patients, and the difference was statistically significant (P < 0.05). There was no statistically significant difference in the grade of liver inflammation and fibrosis (GS stage) between the two groups (P > 0.05). Binary multivariate logistic regression analysis showed that overweight/obesity, triglycerides, low-density lipoprotein, the controlled attenuation parameter for hepatic steatosis, and HBeAg positivity were independent influencing factors for MAFLD in CHB patients. Conclusion: Patients with CHB combined with metabolic disorders are prone to developing MAFLD, and there is a certain correlation between HBV viral factors, the degree of liver fibrosis, and the fatty degeneration of hepatocytes.

Abstract
Nardosinone, a sesquiterpene peroxide, is one of the main active constituents of the ethnomedicine Nardostachyos Radix et Rhizoma, and it has many bioactivities, such as antiarrhythmia and cardioprotection. To elucidate its in vivo existence forms, its metabolism is first studied using mice. All urine and feces are collected during the six days of oral dosing of nardosinone, and blood is collected at one hour after the last dose. Besides, to validate some metabolites, a fast experiment is performed, in which nardosinone was orally administered and the subsequent one-hour urine is collected and immediately analyzed by UHPLC-Q-TOF-MS. In total, 76 new metabolites are identified in this study, including 39, 51, and 12 metabolites in urine, plasma, and feces, respectively. Nardosinone can be converted into nardosinone acid or its isomers. The metabolic reactions of nardosinone included hydroxylation, hydrogenation, dehydration, glucuronidation, sulfation, demethylation, and carboxylation. There are 56 and 20 metabolites with the structural skeleton of nardosinone and nardosinone acid, respectively. In total, 77 in vivo existence forms of nardosinone are found in mice. Nardosinone is mainly excreted in urine and is not detected in the feces. These findings will lay the foundation for further research of the in vivo effective forms of nardosinone and Nardostachyos Radix et Rhizoma.

Abstract
Cholestasis is the most destructive pathological manifestation of liver disease and available treatments are very limited. Paeoniae Radix Rubra (PRR) is an important traditional Chinese drug used to treat cholestasis. This study combined targeted metabonomics, PCR array analysis, and 16S rRNA sequencing analysis to further clarify the mechanisms of PRR in the treatment of cholestasis. PRR conspicuously reversed the elevation of fatty acids (FFA 14:0 and other 14 fatty acids) and the decrease of organic acids (pyruvic acid and citric acid) in a cholestatic model induced by α-naphthyl isothiocyanate (ANIT). Eight elevated amino acids (L-proline, etc.) and five elevated secondary bile acids (taurohyodeoxycholic acid, etc.) in model rats were also reduced by PRR. Pathway analysis revealed that PRR significantly alleviated eight pathways (β-alanine metabolism). Furthermore, we found that PRR significantly reversed the decrease of Cpt1a, Hadha, Ppara, and Slc25a20 (four genes relevant to fatty acid β-oxidation) mRNAs caused by ANIT, and PRR conspicuously decreased nine acylcarnitines (the forms of fatty acids into mitochondria for β-oxidation) that increased in model rats. These results indicate that PRR could enhance fatty acid β-oxidation, which may be the way for PRR to reduce the levels of 15 fatty acids in the serum of model rats. 16S rRNA sequencing analysis revealed that PRR alleviated gut microbiota disorders in model rats, including upregulating four genera (Coprococcus, Lactobacillus, etc.) and downregulating four genera (Bacteroides, Escherichia, etc.). As the relative abundance of these eight genera was significantly correlated with the levels of the five secondary bile acids (deoxycholic acid, taurolithocholic acid, etc.) reduced by PRR, and Bacteroides and Escherichia were reported to promote the production of secondary bile acid, we inferred that the downregulation of PRR on five secondary bile acids in model rats was inseparable from gut microbiota. Thus, the gut microbiota also might be a potential pharmacological target for the anticholestatic activity of PRR. In conclusion, we consider that the mechanisms of PRR in treating cholestasis include enhancing fatty acid β-oxidation and alleviating gut microbiota disorders.

Abstract
In the clinical practice of traditional Chinese medicine, toxic heat and blood stasis syndrome (THBSS) is a common syndrome observed in various critical diseases. Paeoniae Radix Rubra (PRR) has known therapeutic effects on THBSS. However, its pharmacodynamic mechanisms and effective substances in the treatment of THBSS still need further elucidation. Our previous study indicated that THBSS had three stages of progression, and the abnormal biochemical indices of each stage were different. Therefore, this study aimed to elucidate the pharmacodynamic mechanisms and effective substances of PRR for the treatment of THBSS with a stage-oriented strategy. Specifically, research was performed separately in two stable stages of THBSS: the excessive heat and little blood stasis (EHLBS) and blood stasis (BS) stages. THBSS model rats, at different time periods after syndrome initiation (first 5 h for EHLBS and 24 h later for BS), were used to conduct the two-stage investigation. Targeted metabonomics analysis was performed to elucidate the pharmacodynamic mechanisms of PRR in the treatment of EHLBS or BS. Based on the relationship between the individual differences in blood drug concentrations and pharmacodynamic effects, partial least squares regression analysis was employed to screen for the effective substances from the original constituents and metabolites of PRR. We found that PRR could upregulate primary bile acid biosynthesis, glycerophospholipid metabolism, ether lipid metabolism, and five amino acid metabolic pathways (e.g., arginine and proline metabolism) to treat EHLBS. Meanwhile, PRR alleviated BS by upregulating primary bile acid biosynthesis and downregulating glycerophospholipid metabolism. But PRR had no obvious effects on ether lipid metabolism and amino acid metabolism in this stage. In total, 17 and 9 potential effective substances were found in the EHLBS and BS stages, respectively, among which there were only five common compounds between the two stages. To our knowledge, sixteen compounds were regarded as potential effective substances of PRR for the first time. Therefore, the pharmacodynamic mechanisms and effective substances of PRR in the treatment of EHLBS and BS were partly different. Overall, this stage-oriented strategy provides a new way to study the pharmacodynamic mechanisms and effective substances of traditional Chinese drugs.

Abstract
Three new flavonoids, ephedroside A (1), ephedroside B (2), ephedroside C (3), together with fifty-four known compounds 4-57 were isolated from the EtOH extract of the herbaceous stems of Ephedra sinica. The structures of these compounds were elucidated by spectroscopic techniques, as well as by comparison with literature data. Thirty-eight of these compounds were isolated from the genus Ephedra for the first time. The antimicrobial activities of eight compounds were tested by measuring the minimum inhibitory concentrations (MIC) against bacteria (both Gram positive and Gram negative) and fungi, and were found to be in the range of 0.105-0.926 mM. Among them, compound 2 showed the best antimicrobial activity against Pseudomonas aeruginosa with MIC value of 0.105 mM.

Abstract
A high performance liquid chromatography with a diode array detector combined with electrospray ionization ion trap time-of-flight multistage mass spectrometry(HPLC-DAD-ESI-IT-TOF-MS~n, HPLC-MS~n) method was established for qualitative analysis of the chemical components of ethyl acetate extract from Sinopodophylli Fructus. The analysis was performed on a Kromasil 100-5 C_(18)(4.6 mm×250 mm, 5 μm) column, with a mobile phase consisted of 0.1% formic acid(A) and acetonitrile(B) for gradient at a flow rate of 1.0 mL·min~(-1). Electrospray ionization ion trap time-of-flight multistage mass spectrometry was applied for qualitative analysis under positive and negative ion modes. With use of reference substance, characteristic fragmentation and their HR-MS data, 102 components were identified, including 67 flavonoids and 35 lignans. Among them, 45 compounds were reported in Sinopodophylli Fructus for the first time and 19 compounds were identified as new compounds. PharmMapper was used to predict the bioactivity of compounds that were first reported in Sinopodophylli Fructus, and 20 compounds of them were identified to have potential anticancer activity. The results showed that there were many isomers in the ethyl acetate extract of Folium Nelumbinis, and a total of 19 groups of isomers were found. Among them, C_(21)H_(20)O_8 had the highest number of isomers(18 compounds), all of which were α-peltatin or its isomers; C_(21)H_(20)O_7 ranked second, with 10 compounds, all of which were 8-prenylquercetin-3-methyl ether or its isomers. In conclusion, an HPLC-MS~n method was established for qualitative analysis of the ethyl acetate extract(with anti-breast cancer activity) from Sinopodophylli Fructus in this study, which will provide the evidence for clarifying pharmacological active ingredients of the ethyl acetate extract from Sinopodophylli Fructus against breast cancer.

Abstract
Ononin is a bioactive isoflavone of legumes. To explore the "effective forms" of ononin, its metabolites were characterized using HPLC-ESI-IT-TOF-MSn after oral administration to rats. Metabolites (106), including 94 new metabolites, were characterized, which contained 17 phase I, 23 hydroxylated and methylated, 54 sulfated, 10 glucuronidated, and 2 sulfated and glucuronidated metabolites. Six hydroxylated metabolites of formononetin (aglycone of ononin) were simultaneously detected for the first time. Twenty-three hydroxylated and methylated metabolites were the new metabolites of ononin, and the number of hydroxylation and methylation was 1-3 and 1-2. Twenty metabolites have ononin-related bioactivities, and many metabolites have the same bioactivities. Their probable mechanisms of action may be additive and/or synergistic effects, especially because of the addition of the blood concentrations of these compounds. The results provide a foundation for a better understanding of the "effective forms" of ononin.

Abstract
Astragali Radix total flavonoids (ARTF) is one of the main bioactive components of Astragali Radix (AR), and has many pharmacological effects. However, its metabolism and effective forms remains unclear. The HPLC-DAD-ESI-IT-TOF-MSn technique was used to screen and tentatively identify the in vivo original constituents and metabolites of ARTF and to clarify their distribution in rats after oral administration. In addition, modern chromatographic methods were used to isolate the main metabolites from rat urine and NMR spectroscopy was used to elucidate their structures. As a result, 170 compounds (23 original constituents and 147 metabolites) were tentatively identified as forms existing in vivo, 13 of which have the same pharmacological effect with ARTF. Among 170 compounds, three were newly detected original constituents in vivo and 89 were new metabolites of ARTF, from which 12 metabolites were regarded as new compounds. Nineteen original constituents and 65 metabolites were detected in 10 organs. Four metabolites were isolated and identified from rat urine, including a new compound (calycoisn-3'-O-glucuronide methyl ester), a firstly-isolated metabolite (astraisoflavan-7-O-glucoside-2'-O-glucuronide), and two known metabolites (daidzein-7-O-sulfate and calycosin-3'-O-glucuronide). The original constituents and metabolites existing in vivo may be material basis for ARTF efficacy, and these findings are helpful for further clarifying the effective forms of ARTF.

Abstract
Asari Radix et Rhizoma (ARR) is an important traditional Chinese medicine. Volatile organic compounds (VOCs) are the main active constituents of ARR. Research on the metabolite profile of VOCs and the difference of absorbed constituents in vivo after an administration of ARR decoction and powder will be helpful to understand the pharmacological activity and safety of ARR. In this study, headspace solid-phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) was applied to profile the VOCs from ARR in rats in vivo. A total of 153 VOCs were tentatively identified; 101 were original constituents of ARR (98 in the powder-treated group and 43 in the decoction-treated group) and 15 were metabolites, and their metabolic reactions were mainly oxidation and reduction, with only two cases of methylation and esterification, and 37 unclassified compounds were identified only in the ARR-treated group. Of the 153 VOCs identified, 131 were reported in rats after oral administration of ARR for the first time, containing 79 original constituents, 15 metabolites, and 37 unclassified compounds. In the powder-treated group, methyleugenol, safrole, 3,5-dimethoxytoluene (3,5-DMT), 2,3,5-trimethoxytoluene (2,3,5-TMT), and 3,4,5-trimethoxytoluene (3,4,5-TMT) were the main absorbed constituents, the relative contents of which were significantly higher compared to the decoction-treated group, especially methyleugenol, safrole, and 3,5-DMT. In the decoction-treated group, 3,4,5-TMT, 2,3,5-TMT, kakuol, and eugenol were the main constituents with a higher content and wider distribution. The results of this study provide a reference for evaluating the efficacy and safety of ARR.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This study addresses the rapid discovery of the active compounds (the original constituents and/or metabolites) of a traditional Chinese drug, Smilacis Glabrae Rhizoma (SGR). AIM OF THE STUDY The aim of this study was to develop a new method to find out the active compounds of traditional drugs in vivo. MATERIALS AND METHODS A method was established to discover and identify the potential active compounds in drug-containing plasma from rats that were orally administered SGR extract, utilizing the relationship between the individual differences in blood drug concentrations in the rats and the resulting differences in pharmacological effect, and the method was denoted as the RID-PE method. For this method, we used high-performance liquid chromatography with a diode array detector combined with electrospray ionization ion trap time-of-flight multistage mass spectrometry (LC-MSn) to identify the compounds (the original constituents and metabolites) and to determine the peak areas of the compounds in drug-containing plasma following SGR treatment. The anti-inflammatory effect of SGR was evaluated using a carrageenan-induced inflammatory rat model. According to the percent inhibition of paw edema in each model rat (14 rats total) orally administered SGR extract, the plasma samples from the rats were sorted and divided into 7 groups. Each group consisted of two plasma samples, and their percent inhibition of paw edema were similar to each other. We performed an LC-MSn analysis on 3 plasma groups, which showed large differences in the inhibition rates, with percent inhibitions of 92.7%, 72.4% and 38.4%. The correlation coefficients (r) between the peak area of each compound and the pharmacological effect (inhibition ratio) of SGR in the three groups were analyzed using SPSS software. When the correlation coefficients of the compounds are greater than 0.8 (0.8 < r ≤1), these compounds are strongly and positively correlated with anti-inflammatory activity, making them potential anti-inflammatory active compounds. RESULTS Fifty-eight potential anti-inflammatory compounds (0.8 < r ≤ 1) from SGR were discovered in model rat plasma using the RID-PE method, 47 of which were considered to be new potentially anti-inflammatory compounds. Among these compounds, four original constituents and 5 isomers of potential anti-inflammatory metabolites were validated to have significant anti-inflammatory effects, and they included astilbin, syringic acid, catechin, coumalic acid, resveratrol-3'-O-glucuronide (RG, isomer of M2 or M3), 3'-O-methyl-(+)-epicatechin-4'-O-glucuronide (CA-1, isomer of M16), 4'-O-methyl-(+)-epicatechin-3'-O-glucuronide (CA-2, isomer of M16), 4'-O-methyl-(+)-epicatechin-7-O-glucuronide (CA-3, isomer of M16) and 3'-O-methyl-(+)-epicatechin-7-O-glucuronide (CA-4, isomer of M16). In addition, four isomers (CA-1-CA-4) were reported to have anti-inflammatory effects for the first time, and CA-3 was a new compound. CONCLUSIONS The RID-PE method can be used to discover and identify the active constituents and metabolites of SGR systematically and in vivo. Furthermore, these findings enhance our understanding of the metabolism and effective forms of SGR.

Abstract
The present work is to establish an HPLC characteristic chromatograms of Asarum heterotropoides var. mandshuricum(AH) and A. sieboldii(AS), combined with cluster analysis for the identification of the two species, and predict their potential anti-inflammatory related targets by network pharmacological method. Eighty-nine samples(12 batches of AS and 77 batches of AH) were analyzed, and 11 characteristic peaks were identified by reference substances, UV spectrum and LC-MS. Cluster analysis showed that AS and AH were divided into two groups, and the ratio of characteristic peak areas can be used to distinguish them. When the ratio of characteristic peak sarisan to kakuol was greater than 5, it was AS, and when the ratio was less than 2, it was AH. The network pharmacological analysis of 119 constituents of Asari Radix et Rhizoma suggested that the anti-inflammatory effect of Asari Radix et Rhizoma might be related to COX-2, COX-1, iNOS, MAPK14, NR3 C1, PPARG and TNF. Among them, COX-2 is a relatively key target, which interacted with the characteristic constituents, asarinin, sesamin, safrole, methyleugenol and sarisan. The characteristic constituents asarinin and sesamin also interacted with the iNOS and MAPK14. Safrole and sarisan can also interact with iNOS, COX-1 and LAT4 H. Methyleugenol also showed interaction with COX-1 and LAT4 H. Since asarinin and sesamin interacted with three targets, COX-2, iNOS and MAPK14, it implied that they were the main active constituents for the anti-inflammatory activity of Asari Radix et Rhizoma. The COX-2 inhibitory activities of asarinin and sesamin were further studied by molecular docking and bioassay. The HPLC method established was simple, feasible and reliable, with predicted anti-inflammatory targets and anti-inflammatory constituents, which could provide a reference for improving the quality evaluation system of Asari Radix et Rhizoma.

Abstract
Astrapterocarpan (AP) is a bioactive constituent of Astragali Radix and was selected as a model compound for investigating the in vitro metabolism of pterocarpans in this study. Its in vitro metabolism was conducted by incubation with rat hepatic 9000g supernatant (S9) in the presence of an NADPH-generating system. At first, four compounds were isolated and their structures were elucidated as 6a-hydroxy-AP (M1), astrametabolin I [M2, 1a-hydroxy-9, 10-dimethoxy-pterocarp-1(2), 4-diene-3-one], 9-demethyl-AP (M3, nissolin) and 4-methoxy-astraisoflavan (M4, 7, 2'dihydroxy-4, 3', 4'-trimethoxy-isoflavan) on the basis of NMR data, respectively. Among them, M1, M2 and M4 were new compounds. Next, the metabolite profile of AP in rat hepatic S9 was obtained via HPLC-DAD-ESI-IT-TOF-MSn, and 40 new metabolites were tentatively identified. These newly identified metabolites included 9 monohydroxylated metabolites, 1 demethylated metabolite, 7 demethylated and monohydroxylated metabolites, 4 dihydroxylated metabolites, 1 hydration metabolite, 1 didemethylated metabolite, 2 glucosylated metabolites, 1 monohydroxylated and dehydrogenated metabolite, 2 monohydroxylated and demethylated and dehydrogenated metabolites, 2 dimerized metabolites, 3 dimerized and monohydroxylated metabolites, 2 dimerized and didemethylated metabolites, and 5 dimerized and demethylated metabolites. Finally, the major metabolic reactions of AP in rat hepatic S9 were summarized and found to be hydroxylation, demethylation, dimerization, hydration, and dehydrogenation. More importantly, the biotransformation from AP to M2 and the dimerization of AP by incubation with hepatic S9 were reported for the first time. In conclusion, this is the first report on the metabolism of a pure pterocarpan in animal tissues, and these findings will provide a solid basis for further studies on the metabolism of other pterocarpans.

Abstract
Medicarpin is a bioactive pterocarpan that has been attracting increasing attention in recent years. However, its metabolic fate in vivo is still unknown. To clarify its metabolism and the distribution of its metabolites in rats after oral administration, the HPLC-ESI-IT-TOF-MSn technique was used. A total of 165 new metabolites (13 phase I and 152 phase II metabolites) were tentatively identified, and 104, 29, 38, 41, 74, 28, 24, 15, 42, 8, 10, 3, and 17 metabolites were identified in urine, feces, plasma, the colon, intestine, stomach, liver, spleen, kidney, lung, heart, brain, and thymus, respectively. Metabolic reactions included demethylation, hydrogenation, hydroxylation, glucuronidation, sulfation, methylation, glycosylation, and vitamin C conjugation. M1 (medicarpin glucuronide), M5 (vestitol-1'-O-glucuronide) were distributed to 10 organs, and M1 was the most abundant metabolite in seven organs. Moreover, we found that isomerization of medicarpin must occur in vivo. At least 93 metabolites were regarded as potential new compounds by retrieving information from the Scifinder database. This is the first detailed report on the metabolism of ptercarpans in animals, which will help to deepen the understanding of the metabolism characteristics of medicarpin in vivo and provide a solid basis for further studies on the metabolism of other pterocarpans in animals.

Abstract
Mitochondria regulate numerous crucial cell processes, including energy production, apoptotic cell death, oxidative stress, calcium homeostasis and lipid metabolism. Here, we applied an efficient mitochondria-based centrifugal ultrafiltration/liquid chromatography/mass spectrometry (LC/MS) method, also known as screening method for mitochondria-targeted bioactive constituents (SM-MBC). This method allowed searching natural mitochondria-targeting compounds from traditional Chinese medicines (TCMs), including Puerariae Radix (PR) and Chuanxiong Radix (CR). A total of 23 active compounds were successfully discovered from the two TCMs extracts. Among these 23 hit compounds, 17 were identified by LC/MS, 12 of which were novel mitochondria-targeting compounds. Among these, 6 active compounds were analyzed in vitro for pharmacological tests and found able to affect mitochondrial functions. We also investigated the effects of the hit compounds on HepG2 cell proliferation and on loss of cardiomyocyte viability induced by hypoxia/reoxygenation injury. The results obtained are useful for in-depth understanding of mechanisms underlying TCMs therapeutic effects at mitochondria level and for developing novel potential drugs using TCMs as lead compounds. Finally, we showed that SM-MBC was an efficient protocol for the rapid screening of mitochondria-targeting constituents from complex samples such as PR and CR extracts.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Licorice (the roots and rhizomes of Glycyrrhiza uralensis Fisch.) is occasionally used as crude drug following processing including roasting or honey-roasting (soaking with honey before roasting) in traditional Japanese Kampo medicine and traditional Chinese medicine (TCM). AIM OF THE STUDY We investigated the differences in the inducible effect of processed licorice products on granulocyte colony-stimulating factor (G-CSF) secretion in cultured intestinal epithelial cells and elucidated the active ingredients in both unprocessed and processed licorice products. MATERIALS AND METHODS We prepared heat-processed licorice with or without pretreatment with honey, and fractionated the extracts by Sephadex G-100. Enterocyte-like differentiated MCE301 cells were incubated in media comprising a hot water extract of licorice products for 24h, and the concentrations of G-CSF in the media were measured using enzyme-linked immunosorbent assay (ELISA). RESULTS Licorice extract induced G-CSF secretion in MCE301 cells, and the active ingredients of licorice were high molecular compounds. Although the roasted licorice extract exhibited the activity similar to that of the unprocessed licorice extract, honey-roasted licorice extracts exhibited a significantly higher inducible effect on G-CSF secretion in the cells than that of unprocessed or roasted licorice extracts without pretreatment with honey. This enhanced activity was dependent on the temperature and heating time. CONCLUSIONS The enhanced inducible effect of honey-roasted licorice on G-CSF secretion might be attributed to the combined effect of licorice-derived high molecular compounds and heated-honey-derived compounds. The results of this study can scientifically explain the objective of processing via honey-roasting in TCM theory.

Abstract
A new lignan, tirpitzin A (17) together with 20 known compounds (1-16, and 18-21) were isolated from the ethyl acetate soluble fraction of ethanol extract of the aerial parts of Tirpitzia ovoidea. The structure of new compound was elucidated by means of spectroscopic analysis. Of the known compounds, 7-21 were isolated from Linaceae family for the first time. The pharmacological activity of the crude extracts was tested using a mouse inflammation model induced by dimethyl benzene. The results demonstrated that the ethyl acetate soluble fraction had anti-inflammatory activity. Moreover, the cytotoxic and anti-inflammatory activities of some compounds were studied. The new compound 17 showed moderate cytotoxic effect against BxPC-3 cell line (IC50 = 19.51μmol·L-1) and Compound 10 showed significant cytotoxicity against HepG2, HL-60, U87 and BxPC-3 cell lines with IC50 values in the range 4.2-8.3μmol·L-1. Additionally, Compounds 2, 10, 11, and 13 exhibited potent inhibitory effects on LPS-induced nitric oxide production in RAW 264.7 macrophages at the concentration of 50μmol·L-1.

Abstract
Anti-inflammatory compounds were investigated from the ethanol extract of the roots and rhizomes of Asarum heterotropoides var. mandshuricum, a traditional Chinese medicine called Xixin and used for pain and inflammatory. Nine new compounds were isolated, including six new lignans, neoasarinin A–C (1–3), neoasarininoside A and B (4 and 5), and asarinin B (7), and one new monoterpene, asarincin A (8), two new amides, asaramid II and III (10 and 11), and one new natural monoterpene, asaricin B (9), along with 37 known compounds (6, 12–47). Their structures and absolute configurations were elucidated on the basis of spectroscopic methods and chemical analyses. This is the first report of the absolute configuration of asarinin A (6). The 8-O-4′ neolignans (1–5) were reported in the genus Asarum for the first time. The 15 compounds 17, 19, 22–25, 28, 31, 36, 40, 42, 43, 45–47 were isolated from the genus Asarum, and compounds 16, 32, 33, 37 and 39 were isolated from A. heterotropoides var. mandshuricum for the first time. Thirty-seven of the isolates were evaluated for anti-inflammatory activity against the release of β-glucuronidase in polymorphonuclear leukocytes (PMNs) induced by the platelet-activating factor (PAF), and compounds 1, 4, 7, 8, 14, 17–19, 22, 24, 25, 29, 30, 32, 33, 40–43, 45, and 46 showed potent anti-inflammatory activities in vitro, with 27.9%–72.6% inhibitions at 10−5 mol/L. The results of anti-inflammatory assay suggested that lignans obtained from the CHCl3 extract might be the main active components of Xixin.

Abstract
Aristolochic acid I (AA-I) is a strong nephrotoxin, carcinogen, and mutagen found in plants such as the Aristolochia species. The mechanisms underlying AA-I toxicity in the kidneys are poorly understood. In this study, we aimed to gain insight into the mechanism of AA-I nephrotoxicity by analyzing the uptake, subcellular distribution, and intracellular targets of AA-I in the human kidney cell line HK-2 using immunocytochemistry, immunoprecipitation, and LC-MS/MS. In HK-2 cells incubated with 20[Formula: see text][Formula: see text]g/mL AA-I for different periods of time (up to 12[Formula: see text]h), AA-I was detected by a specific monoclonal antibody (MAb) against AA-I, both in the cytoplasm and nuclei. Nuclear localization depended on the exposure time. A protein with the molecular weight of 100 kDa was immunoprecipitated with the anti-AA-I MAb from the AA-I-treated cell lysates and was identified by LC-MS/MS as [Formula: see text]-actinin-4 after digestion of the protein, and was confirmed by immunoblotting with a specific anti-[Formula: see text]-actinin-4 MAb. This evidence shows, for the first time, that [Formula: see text]-actinin-4 is a protein targeted by AA-I in kidney cells. Our findings strongly suggest an association between [Formula: see text]-actinin-4 and AA-I nephrotoxic activity.

Abstract
Taxifolin is a ubiquitous bioactive constituent of foods and herbs. To thoroughly explore its metabolism in vivo, an HPLC-ESI-IT-TOF-MSn method combined with specific metabolite detection strategy was used to detect and identify the metabolites of taxifolin in rats. Of the 191 metabolites tentatively identified, 154 were new metabolites, 69 were new compounds and 32 were dimers. This is the first report of the in vivo biotransformation of a single compound into more than 100 metabolites. Furthermore, acetylamination and pyroglutamic acid conjugation were identified as new metabolic reactions. Seventeen metabolites were found to have various taxifolin-related bioactivities. The potential targets of taxifolin and 63 metabolites were predicted using PharmMapper, with results showing that more than 60 metabolites have the same five targets. Metabolites with the same fragment pattern may have the same pharmacophore. Thus these metabolites may exert the same pharmacological effects as taxifolin through an additive effect on the same drug targets. This observation indicates that taxifolin is bioactive not only in the parent form, but also through its metabolites. These findings enhance understanding of the metabolism and effective forms of taxifolin and may provide further insight of the beneficial effects of taxifolin and its derivatives.

Abstract
Angelicae Sinensis Radix is commonly used in traditional Chinese medicine. Pharmacological studies show that Angelicae Sinensis Radix has clear anticoagulant activity. Therefore, in this study, the anticoagulant activity of crude Angelicae Sinensis Radix extracts was investigated by measuring the thrombin times of the extracts. The results revealed that the petroleum ether-soluble fraction of Angelicae Sinensis Radix exhibited significant anticoagulant activity in vitro, and 26 compounds were characterized by high-performance liquid chromatography with diode array detection combined with electrospray ionization ion trap time-of-flight multistage mass spectrometry. In addition, 5 prototype constituents, 24 in vivo metabolites in rat urine and 7 prototype constituents, and 9 in vitro metabolites in the rat hepatic S9 incubation system of the petroleum ether-soluble fraction were tentatively identified. All metabolites were found from Angelicae Sinensis Radix for the first time. Among them, 13 (three ferulic acid-related constituents, six senkyunolide D-related constituents, and four senkyunolide F-related constituents) were identified as new metabolites (new compounds). This study is the first to qualitatively characterize the chemical constituents of the potent anticoagulative extract of Angelicae Sinensis Radix and to explore its metabolism. The result is a notable improvement in the discovery of Angelicae Sinensis Radix metabolites, and it provides the chemical basis for the effective forms and pharmacodynamic substances (prototypes, metabolites, or both) of the anticoagulant activity of Angelicae Sinensis Radix.

Abstract
Mogroside V, a cucurbitane-type saponin, is not only the major bioactive constituent of traditional Chinese medicine Siraitiae Fructus, but also a widely used sweetener. To clarify its biotransformation process and identify its effective forms in vivo, we studied its metabolism in a human intestinal bacteria incubation system, a rat hepatic 9000g supernatant (S9) incubation system, and rats. Meanwhile, the distribution of mogroside V and its metabolites was also reported firstly. Seventy-seven new metabolites, including 52 oxidation products formed by mono- to tetra- hydroxylation/dehydrogenation, were identified with the aid of HPLC in tandem with ESI ion trap (IT) TOF multistage mass spectrometry (HPLC-ESI-IT-TOF-MS(n)). Specifically, 14 metabolites were identified in human intestinal bacteria incubation system, 4 in hepatic S9 incubation system, 58 in faeces, 29 in urine, 14 in plasma, 34 in heart, 33 in liver, 39 in spleen, 39 in lungs, 42 in kidneys, 45 in stomach, and 51 in small intestine. The metabolic pathways of mogroside V were proposed and the identified metabolic reactions were deglycosylation, hydroxylation, dehydrogenation, isomerization, glucosylation, and methylation. Mogroside V and its metabolites were distributed unevenly in the organs of treated rats. Seven bioactive metabolites of mogroside V were identified, among which mogroside IIE was abundant in heart, liver, spleen and lung, suggesting that it may contribute to the bioactivities of mogroside V. Mogroside V was mainly excreted in urine, whereas its metabolites were mainly excreted in faeces. To our knowledge, this is the first report that a plant constituent can be biotransformed into more than 65 metabolites in vivo. These findings will improve understanding of the in vivo metabolism, distribution, and effective forms of mogroside V and congeneric molecules.

Abstract
8-Prenylkaempferol is a prenylflavonoid that has various bioactivities and benefits for human health. A high-performance liquid chromatography with a diode array detector combined with electrospray ionization ion trap time-of-flight multistage mass spectrometry (HPLC-DAD-ESI-IT-TOF-MS(n) ) method was established to profile and identify the metabolites of 8-prenylkaempferol in rat in vivo and in vitro, and to study the distribution of these metabolites in rats for the first time. A total of 38 metabolites were detected and tentatively identified, 30 of which were identified as new compounds. The new in vivo metabolic reactions in rats of prenylflavonoids of isomerization, polymerization, sulfation, amino acid conjugation, vitamin C conjugation and other known metabolic reactions were found in the metabolism of 8-prenylkaempferol. The numbers of detected metabolites in feces, urine, plasma, small intestine, stomach, kidneys, liver, heart, lungs, spleen and hepatic S9 fraction were 31, 19, 1, 20, 13, 8, 7, 3, 3, 1 and 11, respectively. This indicated that small intestine and stomach were the major organs in which the 8-prenylkaempferol metabolites were distributed. Furthermore, 16 metabolites were determined to have bioactivities based on the literature and 'PharmMapper' analysis. These findings are useful for better comprehension of the effective forms, target organs and pharmacological actions of 8-prenylkaempferol. Moreover, they provide a reference for the study of the metabolism and distribution of prenylflavonoid aglycone compounds.

Abstract
The dried root tubers of Stemona tuberosa, S. japonica and S. sessilifolia are the original sources of Stemonae Radix (SR) for antitussive and insecticidal activities. The products of SR which are available on the market are variable, and imitations exist. In order to characterize the overall chemical constituents of SR and evaluate its quality, a novel, binary high-performance liquid chromatographic fingerprinting method, describing the pattern of alkaloids (fingerprint I) and non-alkaloids (fingerprint II) of SR was developed. It was also applied to determine whether the medicinal parts and the processing methods affect the quality of SR. Similarity and high-performance liquid chromatography-mass spectrometry (HPLC-MS(n)) were utilized to compare or identify the chemical constituents of SR. The results indicate that the chemical constituents from different parts of the underground material of Stemona plants are diverse and that the processing methods affect certain constituents in the root tuber samples. The similarity and the resulting chemical consitituents obtained show that the binary chromatographic fingerprint method can be used to differentiate the three official Stemona species or the adulterants of SR, which is helpful for the identification and quality evaluation of SR.

Abstract
OBJECTIVE To establish a novel cardiocentesis method for withdrawing venous blood from the right atrium, and to improve an acute blood stasis rat model using an ice bath and epinephrine hydrochloride (Epi) while considering the 3Rs (reduction, refinement, and replacement) of humane animal experimentation. METHODS An acute blood stasis model was established in male Sprague-Dawley rats by subcutaneous injection (s.c.) Epi (1.2 mg/kg) administration at 0 h, followed by a 5-min exposure to an ice-bath at 2 h and s.c. Epi administration at 4 h. Control rats received physiological saline. Rats were fasted overnight and treated with Angelicae Sinensis Lateralis Radix (ASLR) and Pheretima the following day. Venous blood was collected using our novel cardiocentesis method and used to test whole blood viscosity (WBV), prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen (FIB) content. RESULTS The rats survived the novel cardiocentesis technique; WBV value returned to normal while hematological parameters such as hemoglobin level and red blood cell count were restored to >94% of the corresponding values in normal rats following a 14-day recovery. Epi (1.2 mg/kg, s.c.) combined with a 5-min exposure to the ice bath replicated the acute blood stasis rat model and was associated with the highest WBV value. In rats showing acute blood stasis, ASLR treatment [4 g/(kg·d) for 8 days] decreased WBV by 9.98%, 11.09%, 9.34%, 9.00%, 7.66%, and 7.03% (P<0.05), while Pheretima treatment [2.6 g/(kg·d), for 8 days] decreased WBV by 25.49%, 25.94%, 16.28%, 17.76%, 11.07%, and 7.89% (P<0.01) at shear rates of 1, 3, 10, 30, 100, and 180 s-1, respectively. Furthermore, Pheretima treatment increased APTT significantly (P<0.01). CONCLUSIONS We presented a stable, reproducible, and improved acute blood stasis rat model, which could be applied to screen drugs for promoting blood circulation and eliminating blood stasis.

Abstract
Traditional Chinese Medicine (TCM) nasal therapy has been utilized to treat numerous diseases for over two millennia. It has many advantages compared with other routes. In this article, headspace-solid phase microextraction-gas chromatography-mass spectrometry and high performance liquid chromatography-atmospheric pressure chemical ionization-ion trap-time of flight-multistage mass spectrometry were applied for the first time to analyze the absorbed constituents in rabbit plasma and cerebrospinal fluid (CSF) after intranasal administration of Asari Radix et Rhizoma (AR). In total, 47 absorbed AR constituents including 14 monoterpenes, 10 phenylpropanoids, four benzene derivatives, two alkanes, nine N-alkylamides and eight lignans were tentatively identified in the rabbit plasma and CSF. Thirty-three absorbed constituents are found to have different bioactivities related to the pharmacological actions of AR through bibliography data retrieval. These indicated that many types of constituents of TCM can be absorbed at the nasal cavity into both rabbit blood and CSF. This is the first study to explore the absorption of AR, and comprehensively analyze the absorbed constituents after intranasal administration of TCM. These findings extend our understanding of the effective substances of AR, and inspire us to make a hypothesis on the mechanism of additive effect of multiple constituents of TCMs, which is very worthy of further investigation.

Abstract
To make a clear understanding of the in vivo metabolism of propyl gallate in rats and determine the original compounds of the metabolites of Paeoniae Radix Rubra (PRR), the urine and plasma of the rats administrated with propyl gallate were collected, and then the HPLC-DAD-ESI-IT-TOF-MS(n) technique was applied to screen and identify the metabolites of propyl gallate from these bio-samples. By comparing the collected LC-MS data, the origin of the metabolites of PRR were confirmed. Finally, 33 metabolites of propyl gallate were identified from urine sample, and 20 metabolites of propyl gallate were identified from the plasma sample. In total, 37 metabolites of propyl gallate were identified, and 17 of them were identical to the metabolites of PRR. They are mainly the phase II metabolites of propyl gallate, 3-hydroxypropyl 3,4,5-trihydroxybenzoate, gallic acid and pyrogallol. Phase I reactions (decarboxylation, hydroxylation) and phase II reactions (sulfation, glucuronidation and methylation) were observed as the main metabolic pathways of propyl gallate. In this research, the in vivo metabolism of proply gallate was reported for the first time and 37 metabolites were identified, among which 35 were new metabolites of propyl gallate, and 20 were new compounds. The results demonstrated that 17 metabolites of PRR can be formed from propyl gallate. This will enhance our understanding of the metabolism and Effective forms (the truly active structures) of propyl gallate and PRR.

Abstract
INTRODUCTION Aristolochic acids (AAs) are naturally occurring nephrotoxicants and human carcinogens. Aristolochic acid I (AA-I) and aristolochic acid II (AA-II) are two important AAs with clear toxicity. OBJECTIVE To obtain a monoclonal antibody (MAb) recognising AA-I and AA-II and develop an Eastern blotting technique for the specific visualisation and easy determination of AA-I and AA-II in plant extracts or tissues of Aristolochia and Asarum species. METHODS A hybridoma secreting MAb against AAs was prepared by cell fusion with splenocytes derived from a mouse immunised with AA-I-keyhole limpet haemocyanin (KLH) conjugate and the myeloma cell line SP2/0-Ag14. AA-I and AA-II were separated by thin-layer chromatography (TLC) and then blotted onto a positively charged polyethersulphone (PES) membrane using a modified carbodiimide method. The resulting membrane-bound AA-protein conjugates were linked to the newly prepared MAb and then to the secondary antibody labelled with peroxidase. 4-Chloro-1-naphthol was then added as the peroxidase substrate for staining. RESULTS MAb 2A10-10B showed a high specificity for AA-I (100%) and AA-II (69.3%) and low cross reactivity (≤ 2.2%) toward analogues that may disrupt detection of AA-I and AA-II in plants. An established Eastern blotting method was applied to the immunohistolocalisation of AA-I and AA-II in dry plant tissues, and this analysis showed that the phelloderm, cortex and phloem of Aristolochia manshuriensis stem may contain higher amounts of total AA-I and AA-II as compared with the pith and xylem. CONCLUSION This method was extremely useful for the visual screening of AA-I and AA-II among easily mistaken herbal medicines.

Abstract
OBJECTIVE To study the HPLC fingerprint of Sinopodophylli Fructus, compare the major chemical differences in fruit of Sinopodophyllum hexandrum as well as the roots and rhizomas of S. hexandrum, and provide scientific evidence for clinical application and quality control. METHOD HPLC fingerprint method was used to analyze 12 fruits of S. hexandrum. A total of 20 common peaks were confirmed, and 12 peaks in the HPLC fingerprint were identified. Furthermore, similarity evaluation method and clustering analysis method were introduced to compare HPLC chromatograms, between fruits and underground parts. RESULT In this paper, quercetin-3-O-beta-D-glucopyranosid, kaempferol-3-O-beta-D-glucopyranoside, 8-prenylquercetin and 8-prenylquercetin 3-methyl ether were firstly reported in Sinopodophylli Fructus. Among the existing fingerprint research, a total of 11 peaks were identified for the first time, containing 9 flavonoids and 2 lignans. The chemical constituents differed significantly in different medicinal parts of S. hexandrum. Prenylflavonoid compounds were the main constituents of Sinopodophylli Fructus. However, podophyllotoxin, flavonoids with simple substituent groups and flavonoid glycosides were the major ingredients in the roots and rhizomas of S. hexandrum. CONCLUSION This method can be used for the quality control of Sinopodophylli Fructus and the roots and rhizomas of S. hexandrum. It has provided a reference for the pharmacodynamic differences of the two different parts.

Abstract
Traditional Chinese medicines (TCM) can be identified by experts according to their odors. However, the identification of these medicines is subjective and requires long-term experience. In this paper, electronic nose, headspace gas chromatography-mass spectrometry (GC-MS) and chemometrics methods were applied to differentiate two species of Asari Radix et Rhizoma by their odors. The samples used were the dried roots and rhizomes of Asarum heterotropoides var. mandshuricum (AH) and Asarum sieboldii (AS). The electronic nose was used to determine the odors of the samples and enabled rapid differentiation of AH and AS when coupled with principal component analysis. Headspace GC-MS was utilized to reveal the differences between the volatile constituents of AH and AS. In all, 54 volatile constituents were identified, and 9 major constituents (eucalyptol, eucarvone, 3,5-dimethoxytoluene, 3,4,5-trimethoxytoluene, methyleugenol, 2,3,5-trimethoxytoluene, croweacin, pentadecane and asaricin) could be used as chemical markers to distinguish these two species. AH contained higher relative contents of eucarvone (1.79-16.76%), 3,5-dimethoxytoluene (6.64-26.52%), 3,4,5-trimethoxytoluene/methyleugenol (6.43-31.67%) and 2,3,5-trimethoxytoluene (1.64-6.66%), whereas AS had higher relative contents of eucalyptol (14.06-24.95%), croweacin (5.64-13.55%), pentadecane (8.44-20.82%) and asaricin (7.03-13.45%). Moreover, AH and AS could be distinguished according to the contents of either all 54 identified volatile constituents or only the 9 major constituents by employing cluster analysis. The proposed method is rapid, simple, eco-friendly and can successfully differentiate these two species of Asari Radix et Rhizoma by their odors.

Abstract
OBJECTIVE To compare the discrepancies between chemical constituents in Dao-di herb and non Dao-di herb of Huangqin (the root of Scutellaria baicalensis), study the impact of habitat and growth pattern (including cultivated and wild Huangqin) on chemical substances of Huangqin, and then provide evidence for the identification of Dao-di herb and quality evaluation of Huangqin. METHOD The chemical constituents in Huangqin collected from different habitats and under different growth patterns, were analyzed using HPLC fingerprint. The fingerprints obtained were then evaluated by hierarchical clustering analysis, principal component analysis and components peak area pattern. RESULT The fingerprints' chemical profiles of Dao-di herb and non Dao-di Huangqin had significant disparity. The fingerprints of modem Dao-di herb Huangqin samples originated from Chengde (Hebei Province) were significantly different from those from other habitats, though the fingerprints of the non Dao-di Huangqin collected from Chifeng (Inner Mongolia) and Chengde had high similarity to each other. The chemical characteristics of Huangqin samples collected from the habitats recorded in ancient herbals, such as Qingyang (Gansu Province), Yan'an (Shaanxi Province), Linyi (Shangdong Province), Changzhi and Jinzhong (Shanxi Province) were similar. The fingerprints of modern non Dao-di samples collected from Dingxi and Longnan (Gansu Province) and Shangluo (Shaanxi Province) had high similarity. In addition, the content of acteoside in wild Huangqin was higher than that in cultivated Huangqin. CONCLUSION Dao-di herb and non Dao-di herb of Huangqin could be distinguished using the developed HPLC fingerprints. The results obtained may provide evidence for the quality control and pharmcodynamical research of Dao-di herb and non Dao-di Huangqin.

Abstract
OBJECTIVE To develop an HPLC method for simultaneous determination of swertiamarin, gentiopicroside, sweroside, mangiferin, erythrocentaurin, and to detect these five constituents in eight Qingyedans derived from Swertia mileensis, S. cincta, S. patens, S. punicea, S. delavayi, S. nervosa, S. macrosperma and S. yunnanensis. METHOD The separation was carried out on a Thermo BDS Hypersil C18 (4. 6 mm x 250 mm, 5 microm) column eluted with mobile phase of water containing 0. 1% phosphoric acid and methanol (B) in gradient program (0-10 min, 18%-20% B; 10-30 min, 20%-35% B; 30-35 min, 35%-60% B). The column temperature was 32 degrees C , and the detection wavelength was set at 250, 260, 225 nm. The flow rate was 0. 7 mL . min-1 from 0 to 30 min, and be increased to 1. 0 mL . min-1 in 35 min. RESULT The five compounds were well separated. The linear response ranges of swertiamarin, gentiopicroside, sweroside, mangiferin, erythrocentaurin were 0. 072-13. 39, 0. 1204. 518, 0. 060-5. 050, 0. 025-1. 518, and 0. 031-0. 210 microg, respectively. The mean recoveries of five compounds were 97.03% -102. 7% (RSD 1. 8% -6.2% ). There are swertiamarin, gentiopicroside and sweroside in most samples, and mangiferin in half samples. But erythrocentaurin was only detected in a few samples. The contents of five compounds were different in different samples. The contents of swertiamarin in S. mileensis, S. patens, S. yunnanensis and S. delavayi are up to 34. 47-118.05 mg . g-1, the contents of gentiopicroside are up to 25. 91 mg . g-1 in S. cincta. In S. puncea all contents of swertiamarin, gentiopicroside, sweroside and mangiferin are higher, especially the content of sweroside. There are Xiao-Qingyedans and Da-Qingyedans called in markets, and they can be identified by the contents of swertiamarin, gentiopicroside and sweroside. S. punicea can be identified by the content of sweroside, and the ratio gentiopicroside/total content can be used for identification of S. cincta from other seven Qingyedan species. CONCLUSION The method was certified to be accurate and reliable and can be used for identification and quality evaluation of traditional Chinese medicine Qingyedan derived from Swertia species.

Abstract
Two aristololactams, aristololactam GI (1) and aristololactam GII (2), and three aporphines, fissistigamide A (3), fissistigamide B (4) and fissistigmine (5), together with nineteen known alkaloids, one flavone and one anthraquinone were isolated from the ethanol extracts of the stems of Fissistigma oldhamii (Annonaceae). Their structures were elucidated primarily by analysis of NMR, IR, UV, MS and CD data. Alkaloid 1 is a chiral aristololactam formed from a phenylpropanoid derivative attached to a 3,4-dihydroxy aristololactam scaffold. The absolute configuration of 1 was determined by comparing experimental and calculated ECD spectra. The anti-inflammatory activity of the crude extracts and the five alkaloids were tested by measuring the amount of TNF-α and IL-6 released from LPS stimulated RAW264 cell via ELISA. The results demonstrated that the CHCl(3)-soluble part and alkaloid 2 exhibited significant anti-inflammatory activity in vitro in both assays.

Abstract
Many Swertia species are utilized as a traditional medicine under the name "Qingyedan" in China, but are easily confused with one another. To distinguish eight Swertia species (S. mileensis, S. cincta, S. patens, S. punicea, S. delavayi, S. nervosa, S. macrosperma, and S. yunnanensis) and to ensure their safety and efficacy, the microscopic and macroscopic characteristics of the roots, stems, leaves, and flowers of them were examined. The results showed that microscopic and macroscopic features helpful for authentication of the eight species were the sinuosity of the anticlinal walls of epidermal cells and presence or absence of hairs on the leaf lamina; presence or absence of V-shaped fibers and fibers with sinuous abaxial wall in the sepals; shape of epidermal cells and pattern of papillae on hairs on the margin of corolla nectary; distribution of stomata in leaf and sepal epidermises, stone cells in cortex and phloem of roots and in cortex and pith of stems, crystals in parenchymatous cells of mesophyll and stem, stomata size, stem diameter, and 4- or 5-merous flowers, and so on. Two keys to the eight Swertia species based on macroscopic and microscopic characteristics are presented. The study indicates that microscopy and related techniques are convenient, practicable, and can be unambiguously applied for authentication of Swertia species.
