Abstract:
Objective To study the chemical constituents of the inflorescence of Echinops latifolius as a Mongolia herbal medicine. Methods The compounds were and purified by column chromatography on silica gel, ODS, and Sephadex LH-20. Their structures were elucidated on the basis of spectroscopic methods, including MS and NMR. Results Fourteen compounds were isolatied from the inflorescence of E. latifolius Tausch, and identified as ψ-taraxasteryl acetate (1), apigenin (2), daucosterol (3), 13-propyl-pentacosane (4), apigenin 7-O-(4″-O-p-coumaroyl)-β-glucoside (5), apigenin-7-O-glucoside (6), caffeic acid (7), 1,5-O-dicaffeoylquinic acid (8), 3,5-O-dicaffeoyl quinic acid (9), methyl 3,4-O-dicaffeoyl quinic acid (10), methyl 3,5-O-dicaffeoyl quinic acid (11), apigenin 7-O-β-D-(4″-p-coumaroyl) glucoside (12), 3,4-O-dicaffeoyl quinic acid (13), and methyl-1-O-methyl 3,5-O-dicaffeoyl quinic acid (14). Conclusion Compounds 1, 4, 5, and 12 are isolated from this plant for the first time. Compound 7-11, 13, and 14 are isolated from the genus Echinops for the first time.
