| 其它 | The chemical constituents from ethyl acetate fraction of Tadehagi triquetrum were studied. The constituents were isolated and purified by column chromatography methods and the structures were identified by spectroscopic analysis.Ten compounds were isolated from ethyl acetate fraction of Tadehagi triquetrum and they were identified as kaempferol( 1),quercetin( 2),vanillic acid( 3),tadehaginoside( 4),cis-tadehaginoside( 5),quercetin-3-O-β-D-glucopyranoside( 6),kaempferol-3-O-β-D-galactopyranoside( 7),kaemnpferol-3-α-L-rhamnoside( 8),kaempferol-3-O-β-D-glucopyranoside( 9),protoeatechuic acid( 10). Compounds 9 and 10 were isolated from Tadehagi triquetrum for the first time. |
