摘要
从中华小苦荬全草的乙酸乙酯提取物中分离得到8个萜类化合物,通过波谱方法及文献对照分别鉴定为β-香树脂素(1),3β-羟基-20(30)-蒲公英甾烯(2),熊果-12-烯-3β-醇(3),羽扇豆醇(4),10-羟基艾里莫芬-7(11)-烯-12,8α-内酯(5),乌苏-12,20(30)-二烯-3β,28-二醇(6),3β,8α-二羟基-6β-当归酰基艾里莫芬-7(11)-烯-12,8β-内酯(7)和乌苏酸(8),化合物1~8均首次从该植物中分离得到。
Eight terpenoids have been isolated from the ethyl acetate extract of Ixeridium chinense(Thunb.) Tzvel by using column chromatography and preparative thin layer chromatography.Structures for all these compounds were proposed on the basis of spectroscopic data,together with comparing their spectral data with those of the corresponding compounds reported in the literature.They were identified as β-amyrin(1),3β-hydroxyl-20(30)-taraxastene(2),olean-12-ene-3β-ol(3),lupol(4),10-hydroxyeremophil-7(11)-en-12,8α-olide(5),ursan-12,20(30)-dien-3β,28-diol(6),3β,8α-dihydroxyl-6β-angloxyeremophil-7(11)-en-12,8β-olide(7) and ursolic acid(8).Compounds 1-8 were obtained from this plant for the first time.
