Abstract

A novel ent-kaurane diterpenoid dimer, fritillebinide B (1) together with one known diterpenoid dimer fritillebinide A (2) were isolated from the bulbs of Fritillaria eheiensis var. purpurea G.D. Yu et P. Li. Compound 1 has been established to be ent-3beta-acetoxy-kauran-16beta,17-acetal ent-16beta-kauran-17(R)-aldehyde (1) by means of spectral analysis and chemical evidence.

摘要

从暗紫贝母（Fritillaria eheiensis var. purpurea G.D. Yu et P. Li）的鳞茎中分离得到一个新的对映-贝壳杉烷二萜二聚体，浙贝乙素B（1）以及一个已知的二萜二聚体浙贝乙素A（2）。通过光谱分析和化学证据确定化合物1为对映-3β-乙酰氧基-贝壳杉烷-16β,17-缩醛对映-16β-贝壳杉烷-17(R)-醛（1）。
