Peanut skin coarse polyphenol antioxidation in vitro

摘要

摘要: 对花生红衣粗多酚抗氧化活性进行研究。采用乙醇、丙酮、蒸馏水3种溶剂提取花生红衣中多酚类物质,通过粗多酚提取液总抗氧化能力（T-AOC）、超氧阴离子自由基（O2-·）清除能力、羟基自由基（·OH）清除作用的测定,比较了3种酚提液的体外抗氧化活性,并测定了其中总多酚含量。结果表明,3种粗多酚提取液总多酚含量分别为9.7%、9.2%、6.3%;在不同抗氧化体系中,3种酚提液均具有良好的抗氧化活性,其中60%乙醇提取液抗氧化能力均高于体积分数0.02%的VC,抗氧化能力的大小顺序为:60%乙醇提取液>60%丙酮提取液>蒸馏水提取液。

Abstract: Antioxidant activity of polyphenols was studied for peanut red skins. Ethanol, acetone, distilled water were used as extraction solvent for polyphenols from peanut red skins. The antioxidant capacity of polyphenols extracts were determined by the total antioxidant capacity (T-AOC) testing, superoxide radical scavenge ability and hydroxyl radicals scavenge ability. The antioxidant activity in vitro of these three polyphenols extracts was compared and the total polyphenols content was determined. The results showed that the total polyphenols content of three polyphenols extracts was at 9.7% , 9.2% and 6.3% . In the different antioxidant system, three kinds of polyphenol extracts had good antioxidant activity, which 60% ethanol extracts oxidation capacity was higher than the volume fraction of 0.02% V C . The order of the three oxidation capacity were 60% ethanol extracts>60% acetone extracts>distilled water extracts.
