红花岩黄芪皂苷的分离鉴定

Saponins from roots of Hedysarum multijugum

目的:研究红花岩黄芪的皂苷成分。方法:应用溶剂法、色谱法提取分离皂苷,用波谱法鉴定其结构。结果:从红花岩黄芪中分离得到4个皂苷,分别为大豆皂苷II甲酯(1),大豆皂苷II(2),大豆皂苷Bg(3)和大豆皂苷I(4),该4个皂苷均为首次从红花岩黄芪分离得到,化合物3为首次从岩黄芪属植物中分离得到,其NMR数据为首次报道。

Objective： To study the chemical constituents from the root of Hedysarum multijugum. Method： The compounds were separated by chromatographic methods, their structures were identified by spectral analysis. Result： Four compounds were isolated and identified as soyasaponin Ⅱ methyl ester （1）, soyasaponin Ⅱ （2）, soyasaponin Bg （3）, and soyasaponin Ⅰ （4）. Conclusion： The four compounds were obtained from the plant for the first time. Compound 3 was isolated from the genus Hedysarum for the first time, and the NMR data of 3 was reported for the first time.
