摘要
应用柱色谱技术从羊角拗[Strophanthusdivaricatus(Lour.)Hook.etAm.]根的甲醇提取物中分离纯化出6个化合物,通过^1HNMR和^13CNMR等波谱技术并对照文献,鉴定其分别为(+)-pinoresinol(1)、沙门苷元(2)、17βH-沙门苷元(3)、羊角拗苷(4)、届-谷甾醇(5)和胡萝卜苷(6)。其中,化合物2-4均为强心苷类化合物。化合物1和3为首次从该植物中分得。
Six compounds were isolated and purified from the roots of Strophanthus divaricatus ( Lour. ) Hook et Arn by repeated column chromatography on silica. The structures were elucidated by the NMR spectral analysis. They were iden- tiffed as ( + ) -pinoresinol ( 1 ), sannentogenin (2), 17βH-sarmentogenin (3), divariooside (4),β-sitosterol ( 5 ) and dau- costerol(6). Except for the compound 1,5 and 6,the other three compounds are cardiac glycosides. Compounds 1 and 3 were obtained from this plant for the first time.
