A Study on in Vitro Antioxidant Activities of Orange Pulp and Peel of Four Ripe Navel Orange Cultivars Planted in South Jiangxi
摘要
Abstract
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 radicals, these four orange cultivars have the same performance as that of orange pulp. By orange peel neutralization activities of · OH free radicals three cultivars (Newhall, Cara, Navelina, Bonanza) have similar performance. But they are statistically better than that of Bonanza with P-value < 0. 05. The neutralization performance of orange peel is better than that of orange pulp. If only considering in vitro antioxidant activities of these four orange cultivars, two culti-vars ( Newhall, Cara) are worthy of expanding their production. And it could be concluded that the side product the orange peel fragment is a rich resource for producing antioxidants.关键词
