苦皮藤中一个倍半萜醇酯新活性化合物的结构

A Novel Bioactive Sesquiterpene Polyol Ester from Angled Bittersweet Leaves(Celastrus angulatus)

从苦皮藤叶中分离得到一个新的倍半萜酸酯化合物。通过光谱和波谱分析，该化合物被 推断为１β，２β，９α－三乙酰氧基－８α－（２－羟基－异丁酰氧基）－１５－苯甲酰氧基－４α－羟基－β－二氢沉香呋喃。 研究了该化合物的结构及立体构型，并对其^（１）Ｈ和^（１３）ＣＮＭＲ谱信号进行了归属。

A new sesquiterpene polyol ester was isolated from the leaves of Celastrus angulatus Maxim. The structure of the compound and its stereo configuration was established mainly on the basis of 1D, 2D NMR and spectroscopic analysis as 13, 29, 9α-triacetoxy-8α- (2-hydroxy-isobutyryoxy )-15-benzoyloxy 4α-hydroxy-β-dihydroagarofuran.
