One new flavonoside and four known compounds were separated from the watersoluble fractions of seed of Oxytropis ochrocephala Bunge by using semi-preparativeHPLC.Four known Compounds have been identified as 2-methyl-3-hydroxy-4H-Pyran-4-one,rhamnocitrin-3-O-β-D-galaetoside-4′-O-β-D-glucoside,rhamnocitrin-3-O-β-D-galactoside,and rhamnocitrin-3-O-β-D-galactoslde.The structure of new flavonoside,as 5-methoxy-7-hydroxy-3-O-β-D-galactoside-4′-O-β-D-glucoside,has been estab-lished on the basis of HPLC retention times and spectral evidences.
