摘　　要：为探明不同品种猕猴桃的体外抗氧化活性差异,本实验研究了三个不同品种猕猴桃果实(徐香、海沃德和哑特)对DPPH·自由基、·OH自由基和ABTS+·自由基的清除能力以及铜离子的螯合能力.结果表明,不同品种猕猴桃的抗氧化能力有显著差异,其中DPPH·自由基清除率在徐香、海沃德和哑特中分别为69.88%、24.88%、52.23%;羟基自由基(·OH)清除率在三个品种中分别中为81.47%、61.60%、71.36%;ABTS+·自由基清除率在三个品种中分别为38.05%、22.45%、35.62%;铜离子螯合能力在这三个品种中分别为77.33%、57.56%、65.12%.上述数据表明三个品种的抗氧化能力由大到小依次为徐香>哑特>海沃德.In order to identify the differences of antioxidant activities in different kiwifruit varieties,this paper studied the scavenging abilities of three kiwifruit varieties(including XuXiang,YaTe and Hayward)on DPPH·free radical,hydroxyl radical(·OH),ABTS+·free radical and the chelating ability of the cupric.The results showed that three kiwifruit varieties displayed different abilities to scavenge free radicals.The scavenging rate of DPPH·free radical in XuXiang,YaTe and Hayward was 69.88%,52.23%and 24.88%,respectively;The scavenging rate of hydroxyl radical(·OH)in the three varieties were 81.47%for XuXiang,61.60%for YaTe and 71.36%for Hayward;The scavenging rate of ABTS+·free radical in in the three varieties was 38.05%,22.45%and 35.62%,respectively;The chelating ability of copper ions in the three varieties was 77.33%,57.56%and 65.12%,respectively.The above data indicated that the antioxidant capacities of the three varieties is XuXiang>YaTe>Hayward.
