苦蝶子的化学成分研究

Chemical constitutes from Ixeris sonchifolia(Bge.) Hance

目的:研究菊科苦荬菜植物苦碟子(Ixeris sonchifolia(Bge.)Hance)的化学成分。方法:利用各种色谱技术进行分离,根据光谱数据鉴定结构。结果:从苦碟子中分离得到7个已知成分,分别鉴定为lir-ioresinol-A(1)、木犀草素(2)、芹菜素(3)、原儿茶酸乙酯(4)、香草醛(5)、对羟基苯甲酸(6)、香草酸(7)。结论:化合物4和7为首次从该植物中分离得到。

Objective： To determine the chemical constituents of Ixeris sonchifolia（Bge.） Hance.Methods： The compounds were separated and purified by column chromatography and their structures were elucidated by spectroscopic methods.Results： Seven compounds were isolated from the chloroform and n-butanol extracts of I.sonchifolia,and determined as lirioresinol-A（1）,luteolin（2）,apigenin（3）,protocatechuic acid ethyl ester（4）,vanillin（5）,4＇-hydroxy cinnamic acid（6） and vanillic acid（7）,respectively.Conclusion： Compounds 4 and 7 are isolated from this plant for the first time.
