为了解类芒齿黄芪(Astragalus camptodontoides)主要化学成分,从其地下部分甲醇提取物的乙酸乙酯部位分离出19个单体化合物,通过现代波谱分析及理化性质等手段分别鉴定为异补骨脂黄酮(1),4’-hydroxyisolonchocarpin(2),5-去氧山豆根黄酮(3),shinflavanone(4),khonklonginols H(5),4’-O-methylpreglabridin(6),3’-hydroxy-4’-O-methylglabridin(7),4’-O-methylglabridin(8),8-prenyl-phaseollinisoflavan(9),xambioona(10),光甘草酚(11),粗毛甘草素H(12),methylnissolin(13),邻苯二甲酸异丁酯(14),邻苯二甲酸丁酯异丁酯(15),β-谷甾醇(16),胡萝卜苷(17),齐墩果酸(18),(2S,3S,4R,9E)-1,3,4-trihydroxy-2-[(2’R)-2’-hydr-oxytetracosanoylamino]-9-octadecene(19)。化合物1~19均为首次从该植物中获得,化合物1~7为首次从黄芪属(Astragalus)植物中分离得到。
In order to understand the main chemical constituents of Astragalus camptodontoides, 19 monomer compounds were isolated from the ethyl acetate fraction of the methanol extract of the underground part, and were identified as isopsoralen by means of modern spectroscopic analysis and physico-chemical properties Flavonoids (1), 4’-hydroxyisolonchocarpin (2), 5-deoxynivalenol (3), shinflavanone (4), khonklonginols H (5), 4’-O-methylpreglabridin -4’-O-methylglabridin (7), 4’-O-methylglabridin (8), 8-prenyl-phaseolinisoflavan (9), xambioona (10), glomerol (11) methylnissolin (13), isobutyl phthalate (14), isobutyl phthalate (15), β-sitosterol (16), daucosterol (17), oleanolic acid (2S, 3S, 4R, 9E) -1,3,4-trihydroxy-2 - [(2’R) -2’-hydr oxytetracosanoylamino] -9-octadecene (19). Compounds 1 to 19 were obtained from this plant for the first time. Compounds 1 to 7 were isolated from Astragalus plants for the first time.
