Abstract: 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.
