To investigate the chemical constituents from Xanthium mongolicum.
The constituents were isolated and purified by silicagel,Sephadex LH-20 column chromatography. Their structures were identified on the basis of spectral data and physiochemical characteristics.
Ten compounds were isolated and identified as hexadecanoic acid( 1), methyl 3, 4-dihydroxybenzoate ( 2), protocatechuic aldehyde( 3), caffeic acid methyl ester( 4), vanillic acid( 5), 4-hydroxybenzoic acid( 6), caffeic acid ethyl ester( 7), chlorogenic acid( 8), caffeic acid( 9), 3, 4-di-O-caffeoylquinic acid( 10).
Compounds 1 ~ 5,7 and 10 are isolated from this plant for the first time.
