Objective:
To investigate the chemical constituents in the herbs of Fallopia convolvulus.
Method:
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.
Result:
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).
Conclusion:
All these compounds were isolated firstly from this plant, compounds 6-9 were obtained from this genus for the first time.
