Abstract

Two new rearranged taxane diterpenoids, 5alpha,7beta,10beta,13alpha-tetrahydroxy-2alpha,9alpha,15-triacetoxy-11(15-->1)-abeo-taxa-4(20), 11-diene (1) and 5alpha,9alpha,10beta,13alpha-tetraacetoxy-15-hydroxy-11(15-->1)-abeo-taxa-4(20), 11-diene (2) have been isolated from the barks of Taxus wallichiana. The structures of these compounds have been confirmed by modern spectroscopic techniques.

摘要

从喜马拉雅红豆杉树皮中分离出两个新的重排紫杉烷二萜类化合物，5α,7β,10β,13α-四羟基-2α,9α,15-三乙酰氧基-11(15→1)-去甲-紫杉-4(20),11-二烯（1）和5α,9α,10β,13α-四乙酰氧基-15-羟基-11(15→1)-去甲-紫杉-4(20),11-二烯（2）。这些化合物的结构已通过现代光谱技术得到证实。
