摘要
基于OH·对luminol化学发光体系有强烈的清除作用,采用声致化学发光技术建立一种评价水果体外总体抗氧化活性大小的方法,在luminol浓度为1×10-3mol/L、超声脉冲作用时间为0.1s、超声脉冲间隔为10s、声致发光池溶液体积为5mL的最佳实验条件下,测定了草莓等十二种水果的抗氧化能力,测定结果为赣南脐橙>大红柚>柳叶桔>菠萝>猕猴桃>草莓>火龙果>圣女果>苹果>油桃>西瓜>甜瓜。
A method for evaluating antioxidant activities of varieties of fruits was developed based on the strong inhibition of the antioxidant the OH. on the chemiluminescence of luminol system.Twelve kinds of fruits such as strawberries of antioxidant activities in luminol concentration to 1 × 10-3 mol/L,0.1s ultrasonic pulse duration, 10s ultrasonic pulse interval and sonochemiluminescence pool solution volume of 5mL under optimum condition was determined as follows. Gannan navel orange 〉 bright red pomelo 〉 willow orange 〉 nectarine 〉 kiwi fruit 〉 strawberry 〉 dragon fruit 〉 cherry tomato 〉 apple 〉 nectarine 〉 watermelon 〉 muskmelon.
