Abstract: Flavonoid are natural organic compounds existing in nature, with a variety of biological activities such as antioxidant, anti-cancer, osteoporosis prevention and immune regulation.Microbes contain a variety of active enzymes, and Flavonoid are structurally modified through microbial fermentation technology to produce more derivatives with novel structures and improve bioavailability,the commonly used microorganisms include Gut microbiota, endogenous microorganisms and some strains with good transformation effect. The transformation reaction type is mainly hydrolysis reaction.The microbial transformation of Flavonoid is mainly based on the mutual transformation of flavonoid glycosides and aglycones. After transformation, a large amount of aglycones can be enriched to improve the bioavailability.Taking soybean isoflavone, Citrus reticulata flavonoids, Scutellaria baicalensis and Epimedium brevicornum flavonoids as examples, this paper summarized and analyzed the research achievements of microbial fermentation of Flavonoid, which can provide a reference for the transformation research of Flavonoid and the research and development of new drugs.

Key words: Microbial transformation, Soybean isoflavone, Citrus reticulata flavonoids, Scutellaria baicalensis flavanoids, Epimedium brevicornum flavanoids
