ABSTRACT
Fourteen compounds were isolated from wholeplants of Carduus acanthoides by various chromatographic techniques including column chromatography over HP-20 macroporous resin, MCI gel, silica gel, Sephadex LH-20 and ODS and reversed-phase HPLC. Their structures were identified as salidroside (1), 2-(3,4-dihydroxyphenyl)-ethyl-O-beta-D-glucopyranoside (2), 3,5-di-hydroxyphenethyl alcohol-3-O-beta-D-glucopyranoside (3), p-coumaric acid (4), 3-hydroxy-1-(4-hydroxy-3-methoxyphenyl) propan-1-one (5), 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl) propan-1-one (6), syringin (7), p-hydroxybenzaldehyde (8), salicylic acid (9), tachioside (10), vanillic acid-4-O-beta-D-glucopyranoside (11), syringic aldehyde (12), 2,6-dimethoxy-4-hydroxyphenol-1-O-beta-D-glucopyranoside (13), and 2, 6-dimethoxy-p-hydroquinone-4-0-P-D-glucopyranoside (14) on the basis of spectroscopic data analysiS. All compounds were isolated from the genus Carduus for the first time except for compounds 4 and 7.
