METHODS Solvent extraction and column chromatography were used. IR, MS, 1HNMR and 13 CNMR spectra were applied for structural elucidation. RESULTS Eight compounds were isolated and identified as genistein(1), sophoraricoside (2), sissotrin(3), sophorabioside(4), kaempferol-7-O-α-L-rhamnoside(5), rutin(6), isoscutellarein(7), and gallic acid(8). CONCLUSION Among them, compounds 3,5,7 and 8 were isolated from this plant for the first time.展开更多
