中文摘要：

对产于广西靖西的山豆根化学成分进行研究,采用硅胶柱层析、重结晶等分离手段从中分离纯化得到10个化合物,通过现代波谱技术和理化常数测定鉴定了它们的结构,分别为：高丽槐素（maackiain 1）,红车轴草苷（trifolirhizin 2）,苷草素（liquiritigenin 3）,7,4＇-二羟基黄酮（7,4＇-dihydroxy-flavone 4）,豆甾醇（stigmasterol 5）,羽扇豆醇（lupeol 6）,十五烷酸（pentadecanoic acid 7）,苯甲酸（benzoic acid 8）,β-谷甾醇（β-sitosterol 9）,胡萝卜苷（daucosterol 10）,其中化合物3,4,6,7,8为首次从该植物中分离得到.

英文摘要：

The chemical constituents of Sophora tonkinensis Gapnep.were studied and ten compounds were isolated by silica column chromatography and recrystallization.The structures of the compounds were elucidated as maackiain（1）,trifolirhizin（2）,liquiritigenin（3）,7,4′-dihydroxy-flavone（4）,stigmasterol（5）,lupeol（6）,pentadecanoic acid（7）,benzoic acid（8）,β-sitosterol（9） and daucosterol（10） by spectral analysis.Compounds 3,4,6,7 and 8 were isolated from this plant for the first time.
