摘要
利用Fenton反应产生羟自由基、邻苯三酚在微碱条件下自氧化产生O-2、磷钼络合物法分别研究了黑米花青苷胶囊和黑米色素对羟基自由基、超氧阴离子的抑制和其总抗氧化活性。结果表明黑米花青苷胶囊和黑米色素能有效清除自由基,具有良好的抗氧化作用。其中黑米花青苷胶囊和黑米色素对羟自由基、超氧阴离子的抑制和其总抗氧化活性随着样品浓度增高而增加。黑米色素对羟自由基、超氧阴离子的抑制和总抗氧化活性显著高于黑米花青苷胶囊。
Producing.OH by Fenton reaction, producing 0.2 by pyrogallol in alkaline conditions and phosphomolybdate complex method were used to study free radical scavenging and antioxidant activity of Black rice anthocyanin capsulest and Black rice anthocyanin. The study showed that Black rice anthocyanin capsulest and Black rice anthocyanin can effectively eliminate free radicals, has a good antioxidant activity. And ability of free radical scavenging and antioxidant activity of Black rice anthocyanin capsulest and Black rice anthocyanin were increasing along with its density. The ability of free radical scavenging and antioxidant activity of Black rice anthocyanin capsulest was lower than the ability of free radical scavenging and antioxidant activity of Black rice anthocyanin.
