摘要
目的研究产自内蒙古杭锦旗的乌拉尔甘草Glycyrrhizauralensis根中的黄酮类成分。方法采用硅胶、聚酰胺、MCI、ODS、SephadexLH-20、RP—HPLC等色谱方法分离纯化,根据理化性质和波谱数据进行结构鉴定。结果从乌拉尔甘草根95%、70%乙醇提取物中分离得到19个化合物,分别鉴定为3-甲基山柰酚(1)、染料木素(2)、柚皮素(3)、甘草异黄酮甲(4)、甘草利酮(5)、异芒柄花素(6)、半甘草异黄酮B(7)、3'-异戊烯基染料木素(8)、黄羽扇豆魏特酮(9)、甘草黄酮醇(10)、黄宝石羽扇豆素(11)、甘草异黄酮乙(12)、异甘草黄酮醇(13)、甘草宁H(14)、粗毛甘草素A(15)、甘草西定(16)、粗毛甘草素D(17)、香豌豆酚(18)、7-甲基羽扇豆异黄酮(19)。结论化合物1、6、8、18、19为首次从甘草属植物中分离得到,化合物2~4、12.14、15为首次从该种植物中分离得到。
Objective To investigate the flavonoids in the roots of Glycyrrhiza uralensis from Hangjinqi, Inner Mongolia. Methods The 95% and 70% ethanol extracts from the roots of G. uralensis were separated and purified by column Chromatography over silica gel, potyamide, MCI, ODS, Sephadex LH-20, and RP-HPLC. Their chemical structures were identified on the basis of physicochemical characteristics and spectral analyses. Results Nineteen compounds were isolated and identified as 3-methylkaempherol (1), genistein (2), naringenin (3), licoisoflavone A (4), licorione (5), isoformononetin (6), semilicoisoflavone B (7), 3'-isoprenylgenistein (8), lupiwighteone (9), licoflavonol (10), topazolin (11), licoisoflavone B (12), isolicoflavonol(13), gancaonin H (14), glyasperin A (15), licoricidin (16), glyasperin D (17), orobol (18), and 7-methyl-luteone (19). Conclusion Compounds 1, 6, 8, 18, and 19 are isolated from the genus Glycyrrhiza Linn. and compounds 2--4, 12, 14, and 15 areisolated from this plant for the first time.
