摘要

摘要从黄芪黄芪的茎皮中分离得到鹿皮醇、鹿皮醇醋酸酯、谷甾醇、豆甾醇和甲基-3-[2-(1-羟甲基乙烯基)2,3-二氢苯并[b]呋喃-5-基]-(E)-2-丙烯酸酯。后者是一种新化合物，已被命名为鲍登酚。它们的结构是借助波谱技术，主要是1和2D核磁共振。鲍登酚的生物发生途径已被提出。

Bowdenol, a New 2,3-Dihydrobenzofuran Constituent from Bowdichia Virgilioides

Abstract From the stem bark of Bowdichia virgilioides, lupeol, lupeol acetate, sitosterol, stigmasterol and methyl-3-[2-(1-hydroxymethylvinyl)2,3-dihydrobenzo[b]furan-5-yl]-(E)-2-propenoate have been isolated. The latter is a new compound and it has been named as bowdenol. Their structures were elucidated with the aid of spectroscopic techniques, mostly 1 and 2D NMR. The biogenetic pathway for bowdenol has been suggested.
