Three kaempferol glycosides were isolated from the flower buds of Panax quinquefolium L. together with kaempferol (1). By means of chemical and spectroscopic methods (NMR, ESI-MS, 2D NMR), their structures were established as trifolin (2), panasenoside (3), and kaempferol-3-O-β-D-glucosyl(1→2)-β-D-galactoside-7-O-α-L-rhamnoside (4).Compound 4 is a new compound.
