Abstract

A new prenylflavanone dimer named bis-sigmodiol was isolated from Erythrina sigmoidea, along with six known constituents isobavachin, lupiwighteone, orientanol A, ergosta-4, 6, 8 (14), 22-tetraen-3-one, lupenyl acetate, and p-hydroxybenzoic acid. These known constituents have not been reported so far from E. sigmoidea. Their structures were elucidated by spectroscopic methods.

摘要

从紫铆刺桐中分离出一种名为双西格莫二醇的新异戊烯基黄酮二聚体，以及六种已知成分异补骨脂查耳酮、羽扇豆魏格酮、东方醇A、麦角甾-4,6,8(14),22-四烯-3-酮、羽扇豆醇乙酸酯和对羟基苯甲酸。到目前为止，这些已知成分尚未见有从紫铆刺桐中报道的。通过光谱方法阐明了它们的结构。
