Abstract

The bioassay-guided fractionation of the MeOH extract from the root of Sophora flavescens led to the isolation of eight known prenylated Flavonoids ( 1 - 8) responsible for the IN VITRO anti-allergic activity. Among them, kushenol N ( 3), sophoraflavanone G ( 6), and leachianone A ( 7) demonstrated significant inhibition of the release of beta-hexosaminidase from cultured RBL-2H3 cells with IC (50) values ranging from 15 to 30 muM.
