摘要: 目的研究多序岩黄芪的化学成分。方法用柱色谱分离,用理化性质及波谱方法鉴定结构。结果从多序岩黄芪中分离鉴定了5个化合物:红芪木脂素A(1),异甘草素(2),7-羟基-4′-甲氧基异黄酮(3),毛蕊异黄酮(4)和芒柄花素(5)。结论化合物1为新化合物,命名为红芪木脂素A。Abstract: AimTo study the chemical constituents of Hedysarum polybotrys Hand.-Mazz.. Methods The compounds were seperated with Sephadex LH-20 and silica gel column chromatography, and their structures were identified on the basis of spectral analysis. ResultsFive compounds were identified as hedysalignan A (1), isoliquiritigenin (2), formononetin (3), calycosin (4) and ononin (5). ConclusionHedysalignan (1) is a new compound and the others were obtained from the plant for the first time.
