ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents in the herbs of Fallopia convolvulus.</p><p><b>METHOD</b>Its 80% ethanol extract was separated by means of silica gel and Sephadex LH-20 column chromatography to give twelve compounds, whose structures were identified by physicochemical properties and spectroscopic evidence.</p><p><b>RESULT</b>Twelve compounds were isolated and identified as quercetin (1), luteolin (2), chrysoeriol (3), apigenin (4), kaempferol-3-O-beta-D-glucoside (5), quercetin-3-O-rhamnoside (6), N-trans-coumaroyl tyramine (7), loliolide (8), ethylparaben (9), beta-sitosterol (10), daucosterol (11), n-hexadecanoic acid (12).</p><p><b>CONCLUSION</b>All these compounds were isolated firstly from this plant, compounds 6-9 were obtained from this genus for the first time.</p>
