Background: Bavachin is a bioactive natural flavonoid with oestrogen‐like activity. Here, we aimed to investigate its metabolic and disposal fates involving in CYPs, UGTs and efflux transporters.

Methods: Phase I metabolism and glucuronidation were performed by human liver microsomes (HLM). Reaction phenotyping and activity correlation analysis were performed to identify the main CYP and UGT isozymes. Chemical inhibition and gene knock‐down approaches were employed to explore the function of BCRP and MRPs.
