Abstract: Two flavonoids were isolated from buds of Panax notoginseng (Burk.) F.H.Chen by silica gel and preparative thin layer chromatography,and identified as kaempferol-3-O-α-L-rhamnoside (1) and kaempferol-3-O- (2″,3″-di-E-p-coumaroyl)-α-L-rhamnoside (2) by physicochemical properties and spectroscopic data.Both compounds were first reported from buds of Panax notoginseng.
