摘要：

Prenylflavonoids and lavandulylflavonoids were isolated from the roots of Sophora flavescens Aiton (Fabaceae). The ability of 8-prenylkaempferol (1), kushenol X (2), norkurarinone (3), leachianone A (4), kushenol C (5), maackiain (6) and a root-extract of S. flavescens to displace 17 beta-estradiol (E2) from rat uterine estrogen receptor (ER) was determined. Relative binding affinities (RBA) of prenylated flavonoids were weak with RBA values between 0.004 and 0.072. A lavandulyl or prenyl group at the position 8 enhanced binding to rat uterine ER.
