Abstract

Two new flavonoids, 6,8,3',4'-tetrahydroxy-2'-methoxy-7-methylisoflavanone (1) and 6,8,3',4'-tetrahydroxy-2'-methoxy-6'-(1,1-dimethylallyl)-isoflavone (2), were isolated from the 95% ethanolic extract of the dried roots of Lespedeza cuneata together with betulinic acid (3), beta-sitosterol (4), hexacosanoic acid 2,3-dihydroxy-propyl ester (5), which were isolated from this plant for the first time. Their structures were elucidated by spectral analysis.

摘要
