桑葚醋提取物抗氧化性的研究

Research on antioxidative activity of mulberry vinegar extract

利用分光光度法测定了桑葚醋提取物羟基自由基清除率、脂质过氧化抑制率和总抗氧化能力。结果表明:桑葚醋提取物的抗氧化能力高于合成抗氧化剂BHA,羟基自由基清除率为79.57%,脂质过氧化抑制率为97.79%,体外总抗氧化能力为110.88mg/mL样品。

The antioxidative activities of mulberry vinegar extract were studied by spectrophotometry, the results proved that mulberry vinegar extract had the stronger antioxidation than BHA; the clear rate of hydroxyl radical was 79.57%; the inhibition rate of lipid radical was 97.79%; and the total antioxidative activity reached 110.88 mg/ml mulberry vinegar extract.
