Abstract: This paper deals with the studies of 2D NMR spectra of disaccharide moiety of a flavonol-3-O-xylosyl-rhamnoside isolated from the aerial parts of Epimedium koreanum.The interlinkage of the biose was determined to be β-D-xylopyranosyl-(1→2)-α-L-rhanmopyranose.A simple NMR criterion was proposed for flavonol-3-O-xylosyl(1→2)-rhamnoside.

Key words: Flavonol-3-O-xylosylrhamnoside, Disaccharide structure, 2D NMR
