红藤化学成分的研究

Studies on the Chemical Constituents of Sargentglor yvine (Sargentodoxa cuneata)

从红藤Sargentodoxacuneata（Oeiv．）Rehd．etWils．茎的乙醇提取物中分得6种结晶单体，经理化性质和波谱数据分析，鉴定了它们的结构分别为β-谷甾醇（Ⅰ）、β-胡萝卜甙（Ⅱ）、崩大碗酸（Ⅲ）、无梗五加甙D（Ⅳ）、红藤甙（Ⅴ）和蔗糖（Ⅵ），其中化合物Ⅴ为一新化合物。

Six compounds were isolated from the EtOH extract of stems of Sargentodoxa cuneata.They were identified as β-sitosterol(Ⅰ), β-daucosterol(Ⅱ), madasiatic acid (Ⅲ), acanthoside D (Ⅳ), sargencuneside(Ⅴ), and sucrose (Ⅵ) on the basis of chemical and spectral analyses. Among them, Ⅴ is a new compound.
