Abstract:
Flavonoids are widely distributed in the nature, and have various biological activities. Flavonoids can be degraded by intestinal bacteria, so as to impact their bioavailability in vivo. Studies on metabolism of flavonoids by intestinal bacteria could provide basis for screening out biotransformation of flavonoids and interpreting their in vivo metabolic process. Being taken as the lead compounds, flavonoids can be modified by intestinal bacteria to achieve new compounds with high efficiency, bioavailability and solubility, which lays a foundation for the research and development of new drugs, selection of drug dosage forms and drug production. This article summarizes the main reaction types and impacting factors of intestinal bacteria on biotransformation of flavonoids, for reference of studies on biotransformation.

Bacterial Flora of the Large Intestine
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.
Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
Methods for Studying Drug Absorption: In vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
