Abstract

The CH(2)Cl(2)/MeOH extract of the stem bark of Erythrina vogelii (Fabaceae) from Nigeria has yielded two novel isoflavones, 7,4'-dihydroxy-8-(gamma,gamma-dimethylallyl)-2''zeta-(4''-hydroxyisopropyl)dihydrofurano[1'',3'':5,6]isoflavone (vogelin H) (1) and 7,4'-dihydroxy-8-[(2'''zeta,3'''-dihydroxy-3'''-methyl)butyl]-2'',2''-dimethyl-3'',4''-dehydropyrano[1'',4'':5,6]isoflavone (vogelin I) (2), a novel flavone, 7,4'-dihydroxy-2'',2''-dimethyl-3'',4''-dehydropyrano[1'',4'':5,6]flavone (vogelin J) (3), and eight known flavonoids.

摘要

从尼日利亚的刺桐（豆科）茎皮中提取的二氯甲烷/甲醇提取物得到了两种新型异黄酮，7,4'-二羟基-8-(γ,γ-二甲基烯丙基)-2''ζ-(4''-羟基异丙基)二氢呋喃并[1'',3'':5,6]异黄酮（沃盖林H）（1）和7,4'-二羟基-8-[(2'''ζ,3'''-二羟基-3'''-甲基)丁基]-2'',2''-二甲基-3'',4''-脱氢吡喃并[1'',4'':5,6]异黄酮（沃盖林I）（2），一种新型黄酮，7,4'-二羟基-2'',2''-二甲基-3'',4''-脱氢吡喃并[1'',4'':5,6]黄酮（沃盖林J）（3），以及八种已知的黄酮类化合物。
