| Notes | Leguminosae; Caragana Ieucophloea; flavonol derivatives; antimicrobial activity; antioxidant activity Three flavonol derivatives have been isolated from the aerial parts of Caragana leucophloea Pojark. （Leguminosae）. By means of pbysicochemical and spectrometric analysis, they were identified as 3-O-methylkaempferol （1）, 3-O-methylquercetin （2）, and quercetin （3）. Among them, 1 exhibited the strongest antibacterial activity with its median inhibitory concentration （ICs0） values on Escherichia coli and Ralstonia solanacearum as 9.00 μg/mL and 7.42 μg/ mL, respectively, and minimum inhibitory concentration （MIC） values on these two bacteria equally as 12.5 μg/mL. Either 2 or 3 showed stronger antioxidant activity than 1. The IC50 values of 2 and 3 on DPPH reduction were 14.39μg/mL and 13.64 μg/mL,respectively,and those on β-carotene-linoleic acid oxidation were 10.26 μg/mL and 9.87 μg/mL, respectively.
