Abstract��
OBJECTIVE To study the constituents in the Oxytropis falcata.METHODS Silica gel column chromatographic method and semi-prepared HPLC were used to separate constituents from CHCl3 and EtOAc extract of Oxytropis falcata.Subsequently,the structures were elucidated by NMR spectral data.RESULTS Six compounds were isolated and elucidated as 2��-methoxy-4��-hydroxy chalcone(��),��-baptigenin(��),formononetin(��),4,2��-dihydroxy-4��-methoxy chalcone(��),7-hydroxy flavone(��) and diisobutyl phthalate(��).CONCLUSION Compound ��-�� were isolated from Oxytropis falcata for the first time,and compound ��,��,�� and �� were isolated from Oxytropis genus for the first time.
