Abstract

Two new prenylated coumarins, sinensins A and B, have been isolated from the roots of Spiranthes sinensis (Pers.) Ames. Their structures were elucidated as 5-gamma, gamma-dimethylallyl-8-[2-(2,6-dihydroxyphenyl)-3-dimethyl-but-2-enyol]-umbelliferon (1) and 4,6-di(gamma, gamma-dimethylallyl)-8-lavandulyl-umbelliferon (2) on the basis of spectroscopic analysis.

摘要

从绶草的根部分离出了两种新的异戊烯基香豆素，即中华素A和中华素B。基于光谱分析，它们的结构被鉴定为5-γ,γ-二甲基烯丙基-8-[2-(2,6-二羟基苯基)-3-二甲基-丁-2-烯醇]-伞形酮（1）和4,6-二(γ,γ-二甲基烯丙基)-8-薰衣草基-伞形酮（2）。
