Eight flavonoids were isolated from Sophora flavescens. Among them, three prenylflavanones: (2S)-6[2(3-hydroxyisopropyl)5-methyl-4-hexenyl]-5-methoxy-7,2',4'-trihydroxyflavanone (1), (2S)-5,4'-dimethoxy-8-lavandulyl-7,2'-dihydroxy flavanone (2) and (2S)-8-(5-hydroxy-2-isopropenyl-5-methylhexyl)-7-methoxy-5,2',4'-trihydroxyflavanone (3) are new compounds. Their chemical structures were determined by spectral methods including 2D NMR. Copyright (c) 2008 John Wiley & Sons, Ltd.
