常见多汁类水果、蔬菜的总抗氧化活性的研究

Study on Total Antioxidant Activity of the Juices of Some Succulent Fruits and Vegetables

通过对市场上常见的多汁类的21种水果和15种蔬菜进行压榨取汁,然后利用DPPH(1,1-diphenyl-2-picrylhydrazy)法测定了它们的总体抗氧化活性,结果表明常见水果中的草莓、荔枝、菠萝等以及蔬菜中的番茄、莲藕、胡萝卜、白萝卜等的抗氧化活性较强,它们对DPPH.的清除率为草莓(98.48%)>荔枝(95.71%)>菠萝(95.15%)>橙(92.83%)>猕猴桃(91.88%)>柠檬(90.56%)>珍珠果(90.15%)等,而番茄(86.81%)>莲藕(77.92%)>胡萝卜(76.19%)>白萝卜(72.28%)等.

The antioxidant activity of the juices of 21 species succulent fruits and 15 species succulent vegetables are evaluated using DPPH method.The results indicated that fruits of strawberry,lychee,pineapple and vegetables such as tomato,lotus root,carrot and radish have strong antioxidant activity.The order of their free radical scavenging ability is strawberry（98.48%） lychee（95.71%） pineapple（95.15%） orange（92.83%）kiwi（91.88%） lemon（90.56%）pearl fruit（90.15%）,and tomato（86.81%） lotus（77.92%） carrot（76.19%） white radish（72.28%）.
