ABSTRACT
OBJECTIVE:
To study the aqueous constituents of Houttuynia cordata.METHOD:
Various 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.RESULT:
Five 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).CONCLUSION:
All compounds were isolated from this plant for the first time.
