Eight flavonoids were isolated from Sophora flavescens . Among them, three prenylflavanones: (2 S )‐6[2(3‐hydroxyisopropyl)‐5‐methyl‐4‐hexenyl]‐5‐methoxy‐7,2′, 4′‐trihydroxyflavanone (1), (2 S )‐5, 4′‐dimethoxy‐8‐lavandulyl‐7, 2′‐dihydroxy flavanone (2) and (2 S )‐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 © 2008 John Wiley & Sons, Ltd.
