Abstract:
OBJECTIVETo study the aqueous constituents of Houttuynia cordata.
METHODVarious columns including Diaion HP-20, Sephadex LH-20, ODS and silica gel were employed for the isolation and purification of compounds from H. cordata. The structures of the compounds were identified by physiochemical properties and spectral analysis.
RESULTFive compounds were isolated, and their structures were identified as chlorogenic methyl ester (1), (E)-4-Hydroxy-4-[3'-(beta-D-glucopyranosyloxy) butylidene]-3, 5, 5-trimethyl-2-cyclohexen-1-one (2), 2-(3, 4-dihydroxyphenyl) ethyl-beta-D-glucopyranoside (3), p-hydroxyphenethyl-beta-D-glucoside (4), 4-(beta-D-glucopyranosyloxy)-3-hydroxy-Benzoic acid (5).
CONCLUSIONAll compounds were isolated from this plant for the first time.
