The interactions between gut microbiota and bioactive ingredients of traditional Chinese medicines: A review.

In recent years, the interaction between the bioactive ingredients of traditional Chinese medicine (TCM) and gut microbiota has been a focus of many studies. When TCM enters the digestive tract, some bioactive ingredients are not absorbed into the gut well thus leading to low bioavailability. Ingredients of TCM are metabolised, or biotransformed by gut microbiota, thereby producing new bioactive molecules, and promote medicine absorption into the circulation. At the same time, the ingredients of TCM effect the composition and structure of gut microbiota, thereby influencing the remote function of diseased organs / tissues through the systemic action of the gut microbiota. In this review, we summarise the gut microbiota-mediated metabolism of flavonoids, alkaloids, terpenoids, saponins, polysaccharides, phenylpropanoids, and organic acids, along with a discussion on the metabolites formed and the biotransformation pathways involving various enzymes. We also highlight the importance of bioactive ingredients of TCM in regulating gut microbiota.

[Variety systematization and research progress of Mongolian medicine "Bashaga"].

Mongolian medicine is the traditional drug with the theory of Mongolian medicine and pharmacy as a guide, which made a great contribution to the survival and development of the Mongolian people. Mongolian medicine "Bashaga" faced the situations of origin is unclear, and clinical therapy is confused and so on. This paper summarizes the original plants and studies the species textual research and ethnopharmacology of Mongolian medicine "Bashaga". This paper intends to ensure authentic plant and provide comprehensive insight into the chemical constituents, pharmacology and application status of Mongolian medicine "Bashaga" to discuss the rationality of the confirmation in "Bashaga" authentic plant.

A review of the ethnopharmacology, phytochemistry, and pharmacology of Changium smyrnioides Wolff.

Changium smyrnioides Wolff is a monotypic species of the genus Changium Wolff which is only found in eastern China. C. smyrnioides has been used as a traditional medicine for ages to treat cough, vomiting, nausea, megrim, and carbuncle. It is also widely used to brew medicated liquor and health tea with other herbs in order to moisten the lungs and nourish blood and yin. This review comprehensively summarizes the up-to-date information on the botanical characterization, distribution, traditional uses, ethnopharmacology, phytochemistry, pharmacology, and toxicity of C. smyrnioides based on studies published in recent years. Phytochemical investigations have revealed that phenylpropanoids, volatile oils, fatty acids, phytosterols, and other bioactive compounds are contained in C. smyrnioides. Crude extracts and monomeric compounds isolated from C. smyrnioides have significant effects on the respiratory, immune, and vascular systems and exhibit favourable activities such as antitussive, eliminating phlegm, anti-asthmatic, immunoregulatory, antioxidant, anti-tumor, anti-fatigue, anti-hypoxia, and anti-atherosclerotic effects. C. smyrnioides is a promising medicinal herb with immense therapeutic and health-promoting effects. Therefore, further studies on the bioactive compounds and mechanisms of C. smyrnioides are necessary. Additional clinical and toxicological studies are warranted to evaluate its safety.
