RESUMO
The latest research shows that the intestinal flora is closely related to the pharmacology of traditional Chinese medicine（TCM）, and the study of microecological mechanism is a new direction of pharmacology of TCM. Among many functional groups of intestinal flora, butyric acid producing bacteria is an important functional group of intestinal flora. It can ferment dietary fiber, carbohydrate, endogenous protein and so on to produce metabolites. The imbalance of its flora is also related to the occurrence of a variety of diseases. The reason is that butyric acid is an important secondary metabolite of butyrobacteria. As an important short chain fatty acid, butyric acid can maintain intestinal health, regulate immune system and inflammatory response, regulate energy metabolism, and affect cell fraction Chemokines and apoptosis play an important role. Polysaccharide of TCM has the characteristics of high content, not easy to be digested and absorbed by the host, but can be decomposed and utilized by intestinal flora. It can be used as the carbon source of bacteria to regulate the intestinal flora, including butyric acid producing bacteria, and improve the structure of intestinal flora to achieve the purpose of disease treatment. Therefore, based on "butyric acid producing bacteria-polysaccharide of TCM", it is a new field in the study of microecological mechanism of TCM to study the pharmacology of TCM from the function of intestinal bacteria and the polysaccharide component of flora carbon source. Based on the latest literature and microecological pharmacology of TCM, this paper reviews the role of butyric acid, the molecular mechanism of butyric acid producing bacteria using polysaccharide of TCM, the relationship between polysaccharide of TCM and butyric acid producing bacteria, and discusses the relationship between butyric acid producing bacteria and polysaccharide of TCM. It also looks forward to the research of TCM pharmacology based on "butyric acid producing bacteria-polysaccharide of TCM", in order to provide a reference for the research progress of TCM pharmacology based on "butyric acid producing bacteria-polysaccharide of TCM".
