摘要:

采用95%乙醇提取,石油醚、乙酸乙酯萃取分部,利用反复硅胶柱和凝胶柱色谱进行分离、纯化,根据波谱技术鉴定结构,研究钩枝藤茎中的化学成分。结果发现:分离得到5个已知二氢黄烷类化合物(-)-表儿茶素-3-没食子酸酯(1)、3,3',5,5',7-五羟基黄烷(2)、(-)-儿茶素(3)、(-)-表儿茶素(4)、(-)-表没食子酸儿茶素(5)和1个酚类化合物(3,5-二甲氧基-4-羟基苯酚)-1-O-β-D-(6-O-没食子酸)葡萄糖苷(6)。其中化合物1、2、4-6均为首次从该植物分离得到。

Abstract:

The chemical constituents of the stems of Ancistrocladus tectorius were isolated by silica gel and Sephadex LH-20 column chromatography,and the structures were elucidated on the basis of spectral analysis. The results showed that five known dihydroflavoids(-)-epicatechin-3-gallate(1),3,3',5,5',7-pentahydroxyflavan(2),(-)-catechin(3),(-)-Epicatechin(4),(-)-epigallocatechin(5)and one known phenolic compound(3,5-dimethoxy-4-hydroxyphenol)-1-O-β-D-(6-O-galloyl)glucose(6)were obtained. Compounds 1,2,4-6 were reported for the first time from this species.
