目的研究紫花松果菊中的化学成分.方法用溶剂法和色谱方法分离紫花松果菊地上部分的化学成分,用波谱技术对分离的化合物进行结构鉴定.结果从紫花松果菊地上部分分离得到了6个化合物.用波谱方法鉴定为2,6-二甲基-7-辛烯-2,3,6-三醇-2-O-β-D-葡萄糖苷(1),7,8-呋喃香豆素(2),6-甲氧基-7-羟基香豆素(3),咖啡酸(4),咖啡酸甲酯(5),咖啡酸乙酯(6).结论 6个化合物均为首次从该植物中获得.“,”Aim To separate and identify chemical constituents of Ehinacea purpurea. Methods Five compoundswere isolated from the plant using chromatography. Their structures were elucidated by spectroscopy. Results Five com-pounds were isolated and their structures were identified as 2, 6-dimethyl-7-octene-2, 3, 6-triol-2-O-β-D-glucopyranoside(1), 7, 8-furocoumarin (2), 6-methoxy-7-hydroxycoumarin (3), caffeic acid (4), methyl caffeate (5), and ethyl caffeate(6). Conclusion All these compounds were obtained from the plant for the first time.
