摘要:

本文为研究白头婆(Eupatorium japonicum)花的化学成分,利用多种色谱技术对白头婆花70%乙醇提取物进行分离得到19个化合物,经NMR、MS等波谱方法鉴定为香豆素(1)、2-hydroxy-2,6-dimethylbenzofuran-3(2H)-one(2)、1-(2-hydroxy-4-methylphenyl)propan-1,2-dione(3)、subamone(4)、(7R*)-opposit-4(15)-ene-1β,7-diol(5)、2,5-二羟基苯甲酸(6))、咖啡酸(7)、9-羟基百里酚(8)、原儿茶酸(9)、反式邻羟基肉桂酸(10)、7-羟基香豆素(11)、槲皮素(12)、蒲公英甾醇(13)、9-acetoxythymol 3-O-tiglate(14)、蒲公英甾醇乙酸酯(15)、亚油酸(16)、9-angeloyloxythymol(17)、豆甾醇(18)、棕榈酸(19)。化合物2~9、11~13、16、19为首次从白头婆中分离得到,化合物4~6、16为首次从泽兰属中分离得到。

Abstract:

To study chemical constituents of the flowers of Eupatorium japonicum.Nineteen known compounds were isolated from the 70% ethanol extraction of the flowers of E.japonicum by various chromatographic methods.On the basis of NMR and MS spectroscopic analysis,their structures were identified as coumarin (1),2-hydroxy-2,6-dimethylbenzofuran-3(2H)-one (2),1-(2-hydroxy-4-methylphenyl)propan-1,2-dione (3),subamone (4),(7R*)-opposit-4(15)-ene-1β,7-diol (5),gentisic acid (6),caffeic acid (7),9-hydroxythymol (8),protocatechuic acid (9),trans-o-hydroxycinnamic acid (10),umbelliferone (11),quercetin (12),traxasterol (13),9-acetoxythymol 3-O-tiglate (14),taraxasterol acetate(15),linoleic acid(16),9-angeloyloxythymol(17),stigmasterol(18),palmitic acid(19).Compounds 2-9,11-13,16,19 were isolated from E. japonicum for the first time,and compounds 4-6,16 were isolated from the genus of Eupatorium for the first time.

Key words: Eupatorium japonicum, chemical constituents, isolation, identification
