摘要: 目的:比较不同水果蔬菜的抗氧化活性。方法:采用DPPH法和FRAP法对15种水果,33种蔬菜的抗氧化活性进行了测定比较,并且分析了抗氧化活性和VC含量的关系。DPPH法测量的结果表明:所测水果中抗氧化活性最强的为花红李,最弱的为水晶梨;所测蔬菜中抗氧化活性最强的为豆角,最弱的为黄瓜、冬瓜;FRAP法测量的结果表明:所测水果中抗氧化活性最强的为橙子,最弱的为水晶梨和香梨;所测蔬菜中抗氧化活性最强的为红辣椒,最弱的为丝瓜和黄瓜。结论:不同的方法测出的抗氧化活性的大小不同,水果和蔬菜中的抗氧化活性成分值得进一步研究。

Abstract: Objective: To compare the antioxidant activities of different kinds of vegetables and fruits respectively. Methods: The DPPH and FRAP methods were used to measure the antioxidant activities of 15 kinds fruits and 33 kinds of vegetables. Results: The plum is the strongest and shuijing pear is the weakest in antioxidant activity among the fruits t for scavenging DPPH free radicals; Among the vegetables,the kidney bean is the strongest in scavenging DPPH free radicals,and cucumber and sponge gourd are the weakest. The orange has the strongest of total antioxidant activity among the fruits,and crystal pear and bergamot pear have the weakest total antioxidant activities. The chillis has the strongest total antioxidant activity among the vegetables,and sponge gourd and cucumber are the weakest in total antioxidant activity. Conclusion: some vegetables and fruits possess strong antioxidant activities and are worth studying fwrther.
