    Abstract As a prescription for treating lung inflammation and intestinal diseases, Xuanbai Chengqi Decoction (XBCQD) in clinical practice can effectively treat COPD with excessive heat in the lung and fu-organs, which is characterized by phlegm-heat accumulation in the lung and constipation. This study aims to find the potential biomarkers of COPD with excessive heat in the lung and fu-organs from two aspects of lung and intestine based on metabolomics and microbiota analysis, and to evaluate the efficacy of XBCQD as well as to explore the mechanism of drug function according the regulating effect of drugs on these markers. The HPLC-Q-TOF-MS/MS, 16SrDNA technology and multiple statistical methods were used to trace the process of disease and curative effect with XBCQD. Results showed that the onset and development of disease was associated with the imbalance of 41 differential metabolites in plasma, bronchoalveolar lavage fluid and feces and 82 bacteria at the levels of phylum, class, order, family and genus from lung and intestine, including Escherichia-Shigella. However, after treatment with XBCQD, 30 differential metabolites mainly involving in the metabolism of linoleic acid, taurine and hypotaurine metabolism, arachidonic acid metabolism, biosynthesis of primary bile acids, tryptophan metabolism, arginine and proline metabolism and 65 pulmonary and intestinal bacteria at all levels were reversed in the drug group. In addition, the results of the correlation analysis showed that specific microbiota from lung and intestine and reversed differential metabolites had a significant correlation, and they could affect each other in the course of disease occurrence and treatment. This study preliminarily confirmed that XBCQD can be used to treat COPD with excessive heat in the lung and fu-organs through lung-intestine simultaneous treatment. It also provided new strategies for the treatment of lung diseases or intestinal diseases, and new research ideas for the evaluation of drug efficacy.

    Abstract Leonurus japonicus Houtt. (Motherwort) is the fresh or dried aerial part of Leonurus japonicus Houtt. (Labiaceae), which is widely used in clinical practice and daily life, used to treat gynecological diseases. However, the differences between different parts, single index component in Pharmacopoeias and the less stability of active ingredients affect its clinical efficacy. This study aimed to find the multi-active compounds between different parts of Motherwort to ensure its clinical efficacy, which related to stability and had pharmacokinetic behavior. Firstly, HPLC-Q-TOF-MS/MS was used to analyze the components in vitro and in vivo, as well as multivariate statistical analysis and network pharmacology analysis was conducted to find the significant different components related to activity. Secondly, the content determination methods were established to study the stability of effective components during storage in order to establish the content limit for quality control of Motherwort. Thirdly, UFLC-MS/MS was used to analyze the pharmacokinetic behavior of active components in Motherwort. The results showed that a total of 131 chemical constituents were identified in vitro and 21 prototype absorption compounds and 72 metabolites were found in vivo. Meantime, multivariate statistical analysis and network pharmacology analysis was combined to find that leonurine, stachydrine and trigonelline were activity-related substance, which could be used as active components related to pharmacodynamics in different parts. Then the stability variation trend and content limit of three alkaloids were found, which could be used for the quality control of Motherwort. Furthermore, the results showed that three alkaloids had pharmacokinetic behavior in vivo. 3 alkaloids were screened, which could be used as active components most closely related to pharmacodynamics among different parts. The stable stage, assay tolerance and pharmacokinetic characteristics were studied by the active substances, which could provide a basis for quality control and clinical medication of Motherwort.

    Abstract Short‐chain fatty acids are currently the most studied metabolites of gut microbiota, but the analysis of them, simultaneously, is still challenging due to their unique property and wide concentration range. Here, we developed a sensitive and versatile high‐performance liquid chromatography with ultraviolet detection method, using pre‐column derivatization and solid‐phase extraction segmental elution, for the quantification of both major and trace amounts of short‐chain fatty acids in human feces. Short‐chain fatty acids were converted to 3‐nitrophenylhydrazine‐derived analytes, and then solid‐phase extraction segmental elution was used for extraction of major analytes and enrichment of trace analytes. The method validation showed limits of quantitation ˂0.04 mM, and coefficient of determination > 0.998 at a wide range of 0.04–8.0 mM. The intra‐ and interday precision of analytes were all within accepted criteria, and the recoveries were 96.12 to 100.75% for targeted analytes in fecal samples. This method was successfully applied in quantification of eight analytes in human feces, which therefore could provide a sensitive and versatile high‐performance liquid chromatography with ultraviolet detection method for precise and accurate quantitation of short‐chain fatty acids in human feces.

    Abstract Gleditsiae Spina, the thorn of Gleditsia sinensis Lam., has been used as an anti-inflammatory, anti-tumor, and anti-bacterial traditional medicine for hundreds of years in China. This study used high-performance liquid chromatography and tandem mass spectrometry combined with chemometric methods to allow the fast and accurate identification and quantification of the flavonoids compounds in Gleditsiae Spina, and created reliable criteria for accurate identification of Gleditsiae Spina and its adulterants. This research provides good evidence for the classification and quality evaluation of Gleditsiae Spina. Firstly, eight flavonoids compounds were detected and identified on the basis of their mass spectra, fragment characteristics, and comparison with published data. Then the mass spectroscopic fragmentation pathways of these compounds were determined and, in addition rutin, isoquercitrin, and quercitrin were detected in Gleditsiae Spina for the first time. The quantification was performed on a triple quadrupole tandem mass spectrometer in multi-reaction monitoring mode, and the baseline separation of the eight bioactive flavonoids components was achieved within 13 min. Furthermore, the proposed method was successfully applied for simultaneous quantitative determination of the eight Gleditsiae Spina compounds and adulterants obtained from different sources in China. Then, we built a classification model which showed a high level of accuracy predicting 100% of the samples, correctly.

    Abstract Short-chain fatty acids (SCFAs) are the main microbial fermentation products from dietary fibers in the colon, and it has been speculated that they play a key role in keeping healthy in the whole-body. However, differences in SCFAs concentration in the serum and colon samples had attracted little attention. In this study, we have optimized the extract and analysis methods for the determination of ten SCFAs in both serum and colon content samples. Methanol and acetonitrile were chosen for extraction of SCFAs from serum and colon content samples, respectively. Biological samples were collected from Alzheimer's disease rats treated by extract of

    Abstract Ophiopogonis Radix (Maidong in Chinese), the tuberous roots of Ophiopogon japonicus having polysaccharide as the main active ingredient, is a traditional Chinese herb and popularly used as functional food additive in China. Here, a homogeneous polysaccharide fraction (OJP-W1) was isolated and characterized from Ophiopogonis Radix collected from Sichuan (Chuan-Maidong). The therapeutic effects of OJP-W1 in diabetes symptoms, gut microbiota and metabolism of short-chain fatty acids (SCFAs) in high-fat diet (HFD)-induced type-2 diabetes mice were investigated. Results showed that OJP-W1 significantly ameliorated HFD-induced insulin resistance and glucose tolerance. Meanwhile, OJP-W1 regulated the gut microbiota dysbiosis in HFD-fed mice, as indicated by increasing Actinobacteria and Bifidobacterium, decreasing Proteobacteria and type-2 diabetes-enriched taxa (e.g. Desulfovibrionaceae, Dorea and Ruminococcaceae). In addition, OJP-W1 could improve the metabolic disorder of SCFAs in HFD-fed mice. This study indicated that OJP-W1 might serve as a novel functional food in preventing diabetes-associated gut microbiota dysbiosis and SCFA metabolic disorder.

    Abstract Hair analysis is with the advantage of non-invasive collection and long surveillance window. The present study employed a sensitive and reliable liquid chromatography coupled with ion trap-time of flight mass spectrometry method to study the metabonomic characters in the hair of 58 heroin abusers and 72 non-heroin abusers. Results indicated that certain endogenous metabolites, such as sorbitol and cortisol, were accelerated, and the level of arachidonic acid, glutathione, linoleic acid, and myristic acid was decreased in hair of heroin abusers. The metabonomic study is helpful for further understanding of heroin addiction and clinical diagnosis.

    Abstract Background: Polygoni Multiflori Radix, He-Shou-Wu in Chinese, is a widely used traditional Chinese medicine. Clinically, water decoction is the major application form of He-Shou-Wu. Therefore, simultaneous determination of bioactive compounds in water extract is very important for its quality control.
    Results: A pressurized liquid extraction and short-end injection micellar electrokinetic chromatography (MEKC) were first developed for simultaneous determination of seven hydrophilic bioactive compounds in water extract of He-Shou-Wu. The influence of parameters, such as pH, concentration of phosphate, SDS and HP-β-CD, capillary temperature and applied voltage, on the analysis were carefully investigated. Optimum separation was obtained within 14 min by using 50 mM phosphate buffer containing 90 mM SDS and 2% (m/v) HP-β-CD (pH 2.5) at 15 kV and 20°C. All calibration curves showed good linearity (R2>0.9978) within test ranges. The overall LOD and LOQ were lower than 2.0 μg/mL and 5.5 μg/mL, respectively. The RSDs for intra- and inter-day of seven analytes were less than 3.2% and 4.6%, and the recoveries were 97.0%-104.2%.
    Conclusion: The validated method was successfully applied to the analysis of He-Shou-Wu samples, which is helpful for its quality control.
