Abstract: A flavonoid glycoside has been isolated from Oxytropis glabra D C (Leguminosae). This flavonoid was identified to be 3-O-[α-L-rhamnopvranosyl (1-6)-β-D-glncopyranosyl]-kaempferol by 2D NMR[1H-1H and 1H-13C (one-bond and long-range) COSY] and other physical-chemical methods.

Key words: 2D NMR, Oxytropis glabra, Flavonoid
