Abstract

Two novel taxane diterpenoids were isolated from the needles of Japanese yew, Taxus cuspidata, and their structures were determined to be lbeta-hydroxy-7beta-acetoxytaxinine (1) and lbeta,7beta-dihydroxytaxinine (2) on the basis of spectral analyses including 2D-NMR studies.

摘要

从日本红豆杉（Taxus cuspidata）的针叶中分离出两种新型紫杉烷二萜类化合物，基于包括二维核磁共振研究在内的光谱分析，确定它们的结构分别为1β-羟基-7β-乙酰氧基紫杉宁（1）和1β,7β-二羟基紫杉宁（2）。
