Abstract

A new labdane-type diterpenoid glucoside and two new labdane-type diterpenoids were isolated from the fruit (chasteberry) of Vitex agnus-castus L. (Verbenaceae) along with 14 known compounds comprising seven labdane-type diterpenoids, one halimane-type diterpenoid, two oleanane-type triterpenoids, two ursane-type triterpenoids, one aromadendrane-type sesquiterpenoid, and one flavonoid. Their structures were characterized on the basis of spectroscopic data as well as chemical evidence. Furthermore, the antioxidative activities of the flavonoid were evaluated using five different analyses.

摘要

从马鞭草科植物贞节树（Vitex agnus-castus L.）的果实（贞节果）中分离出一种新的半日花烷型二萜糖苷和两种新的半日花烷型二萜，同时还分离出14种已知化合物，包括七种半日花烷型二萜、一种哈利曼烷型二萜、两种齐墩果烷型三萜、两种乌苏烷型三萜、一种芳樟烷型倍半萜和一种黄酮类化合物。它们的结构通过光谱数据以及化学证据得以表征。此外，使用五种不同的分析方法对该黄酮类化合物的抗氧化活性进行了评估。
