野马追化学成分

对野马追Eupatorium lindleyanum的化学成分进行研究。采用硅胶、Sephadex LH-20等柱色谱方法对其乙酸乙酯萃取部位进行分离纯化,并根据其理化性质及波谱数据鉴定结构。从野马追中分离得到16个化合物,分别鉴定为东莨菪素(scopoletin,1)、6,7-二甲氧基香豆素(6,7-dimethylesculetin,2)、泽兰叶黄素(nepetin,3)、泽兰黄素(eupatrin,4)、木犀草素(lute-olin,5)、异槲皮苷(isoquerecitrin,6)、棕矢车菊素(jaceosidin,7)、槲皮素(quceritin,8)、山柰酚(kaempferol,9)、芦丁(rutin,10)、线蓟素(cirsiliol,11)、蒲公英甾醇乙酸酯(taraxasteryl acetate,12)、伪蒲公英甾醇乙酸酯(pseudotaraxasteryl acetate,13)、伪蒲公英甾醇(pseudotaraxasterol,14)、丁酸(butanoic acid,15)、正十六烷酸(n-hexadecanoic acid,16)。其中化合物1～6,11,13,15为首次从野马追植物中分离得到。

Chemical constituents of Eupatorium lindleyanum

To study chemical constituents of Eupatorium lindleyanum. Ethyl acetate extractive fractions were separated with silica gel and Sephadex LH-20 by column chromatography, and their structures were identified on the basis of spectroscopic analysis and chemical evidence. Sixteen compounds were separated and identified as scopoletin (1), 6, 7-dimethylesculetin (2), nepetin (3), eupatrin (4), luteolin (5), isoquerecitrin (6), jaceosidin (7), quceritin (8), kaempferol (9), rutin (10), cirsiliol (11), taraxasteryl acetate (12), pseudotaraxasteryl acetate (13), pseudotaraxasterol (14), butanoic acid(15)and n-hexadecanoic acid (16). Of them, compounds 1-6 and 11, 13 and 15 were separated from this plant for the first time.
