Objective To investigate the chemical constituents from the whole plants of Gynura procumbens. Methods The chemical constituents were isolated and purified by silica gel, Sephadex LH-20, and ODS. Their structures were determined by physicochemical properties and spectroscopic analysis. Results Twenty-seven compounds were identified as dibutyl phthalate(1), ursolic acid(2), kaempferol 3-O-β-D-glucopyranoside(3), 5-hydroxymaltol(4), 4-hydroxylbenzoic acid(5), 4-aminocinnamic acid(6),(E)-2-hexenyl β-D-glucoside(7), 1-(3-indolyl)-2,3-dihydroxy-propan-1-one(8), kaempferol-7-O-β-D-glucoside(9), quercetin-3-O-β-Dglucopyranoside(10), 3,4,5-tri-caffeoylquinic acid methyl ester(11), rutin(12), hesperidin(13), 3,4-dihydroxyphenylacetic acid methyl ester(14), euscophic acid(15), tormentic acid(16), 2-methoxy-4-(2-propenyl)-phenyl-O-β-D-glucopyranoside(17), negletein(18), 4,5-dihydroxy-3-methoxybenzoic acid(19), caesalpiniaphenol D(20), gentisic acid(21), 3,4-dihydroxybenzaldehyde(22), isohematinic acid(23), icariside B1(24), dendranthemoside B(25), 4-methoxycinnamic acid(26), and baicalin(27). ConclusionCompounds 1, 2, 10, and 12 are obtained from the plants of G. procumbens for the first time, and compounds 4, 6—9, 11, 13—16, and 17—27 are obtained from Gynura genus for the first time.
