【摘要】分别以清除DPPH·、ABTS+·和·OH自由基效果综合评价赣南主栽的4个脐橙品种成熟果实的抗氧化性,结果表明:4个脐橙品种果肉清除3种自由基的效果,红肉与纽荷尔相似,林娜与朋娜相似;但红肉和纽荷尔清除3种自由基的效果分别显著地(P<0.05)高于林娜与朋娜.4个品种脐橙果皮清除DPPH·和ABTS+·自由基的效果与果肉一致,清除·OH自由基的效果纽荷尔、红肉、林娜3品种相似,但显著地高于朋娜(P<0.05).4个脐橙品种果皮清除3种自由基效果均优于果肉.因此,从抗氧化角度考虑,纽荷尔、红肉脐橙值得在当地进一步扩大栽培面积,加工厂废弃的脐橙皮渣是可供利用的抗氧化资源.%In vitro antioxidant activities of orange peel and pulp of four ripe navel orange cultivars (Ne-whall, Cara, Navelina, Bonanza) , which are cultivated in South Jiangxi, are assessed with DPPH · , ABTS+ · and o OH free radical neutralization approaches in this paper. The results show that by orange pulp in vitro antioxidant activities these four orange cultivars are categorized into two groups, group A formed by Newhall and Cara, and group B formed by Navelina and Bonanza. There is no statistical difference between the groups. But the performance of group A is statistically better than that of group B with P - value <0.05. By neutralization activities of orange peel on DPPH o and ABTS + · free
