Abstract:
To study the chemical constituents of Cirsium pendulum Fisch. ex DC. Thirteen compounds were obtained from ethanol extract of Cirsium pendulum Fisch. ex DC. These compounds were characterized by spectroscopic analysis and comparison with published data to be beta-sitosterol(1), alpha-spinastenorl(2), taraxasterol(3), triacontanol(4), chlorophylla(5), lutein(6), linarin(7), 3-sitosterol-3-O-beta-D-glucopyranoside (8), 3', 4'-dihydroxy phenylethanol glucoside(9),3-(4'-methoxy-3',5'-dihydroxyphenyl)-allyl alcohol glucoside (10), uracil (11), methyl chlorogenate (12), chlorogenic (13). All of them were isolated from this plant for the first time.
