Studies on the constituents of Sophora flavescens aiton. II.

Abstract

Two flavanones, kushenol A (1) and kushenol B (2), one flavonol, kushenol C (3), one chalcone, kushenol D (4), and one pterocarpan, kushenin (5), were isolated from the dry roots of Sophora flavescens AITON (Leguminosae). Their structures were elucidated on the basis of elemental analyses and spectral data.
