    摘要:

    检测了小黑药的多糖含量和抗氧化活性。结果表明:小黑药地上、地下部分多糖含量分别为2.155、2.329 g/100 g;多糖浓度大于100.8 µg/mL时其还原能力超过芦丁;随着质量浓度的增加小黑药多糖抑制超氧阴离子自由基的能力逐渐增大,浓度高于13.44 µg/mL时其抑制率大于芦丁;多糖质量浓度大于42.00 µg/mL时,清除DPPH能力大于芦丁;清除羟基自由基的能力明显高于芦丁,质量浓度为8.06 µg/mL时,多糖对羟基自由基的清除能力达到95.40%。小黑药多糖具有很好的抗氧化活性。

    Abstract:

    The polysaccharides contents and antioxidant activity of Sanicula astrantiifolia Wolff were detected. The results showed that: the polysaccharides contents in aboveground and underground part of Sanicula astrantiifolia Wolff were 2.155 and 2. 329 g/100 g respectively; when the polysaccharides concentrations were more than 100.8 µg/mL, the reducing ability of polysaccharides was higher than rutin; the inhibition ability to the superoxide anion free radical ( O2ˉ· ) gradually increased with the increasing of mass concentration; when the polysaccharides concentrations were more than 13.44 µg/mL, the inhibition rate was higher than rutin; The scavenging capacity of DPPH radical was higher than rutin when the polysaccharides concentrations were more than 42.00 µg/mL; the scavenging ability to hydroxyl radical (·OH) was significantly higher than rutin, and when the mass concentration was 8.06 µg/mL, the ability reached 95.40%; the polysaccharides of Sanicula astrantiifolia Wolff have good antioxidant activity.
