Research Progress of Butyrate-producing Bacteria in Regulating Intestinal Microecology and Interventional Effect of Chinese Herbal Medicine / 中国实验方剂学杂志

ABSTRACT

Butyrate-producing bacteria are specific intestinal bacteria with butyrate as the main metabolite, and most of them are Firmicutes.Butyrate-producing bacteria can synthesize butyrate with non-digestible carbohydrates in the diet, and then regulate intestinal microecology and microenvironment, thereby supplying energy to intestinal epithelial cells, affecting intestinal mucosal barrier, adjusting intestinal flora structure and regulating host immunity, so as to alleviate obesity, hypertension and other diseases.Therefore, the targeted regulation of butyrate-producing bacteria and butyrate has become a potential vital method for the prevention and treatment of many diseases.After oral administration, Chinese herbal medicine (CHM) enters the body, and first contacts gastrointestinal tract, so the interaction between CHM and microbiota existing in the intestine is an inevitable important process.It has been confirmed that CHM could regulate intestinal flora; and due to its complex composition and numerous components, CHM can exert interventional effects at multiple levels, in multiple pathways and on multiple targets.Its effect on the butyrate-producing bacteria is as follows.In the intestinal tract, CHM can play a " prebiotic" role, and enrich the beneficial butyrate-producing bacteria, and polysaccharides in CHM can be used as a fermentation substrate to promote the synthesis of butyrate, so as to achieve the effective regulation of butyrate-producing bacteria and butyrate.Based on that, this paper explored the relationship among butyrate-producing bacteria, butyrate and intestinal microecology, and reviewed relevant researches about the intervention of CHM on butyrate-producing bacteria to regulate intestinal microecology in recent years, in order to provide new research ideas for the application of CHM to prevent and treat diseases, as well as drug development.
