摘　　要： 天然蔬果内一般都含有VC、VE等抗氧化物质,这些物质能够与氧自由基上的未成对电子作用,将其还原为无毒物质,对于减缓机体衰老具有较好的作用。以番茄和胡萝卜作为研究对象,用库仑滴定法测定番茄和胡萝卜的VC含量,再分别用它们去饲养实验小鼠,采用邻苯三酚自氧化法,从而得出小鼠血液SOD活性和抗氧化水平。结果显示,饲料中添加了这些天然瓜果的小鼠血液中SOD活性较只用饲料喂养的小鼠血液中的SOD活性高,且混合饲养的效果更好,从而得出摄食番茄和胡萝卜均能对小鼠体内抗氧化水平的提高有正向作用。 Fresh melon and fruit usually contain antioxidants, such as VC and VE, which can have actions on the unpaired electrons of oxygenic free radical, to reduce them into innoxious matters. These can make a good effect on slowing the aging of body. Take tomato and radish as objects of research, which firstly test their VC content by the method of coulometric titration, and secondly fed the rats respectively. After two weeks, the activities of enzyme SOD in the blood of rats were tested on method of pyrograllol anti-oxidation by using ultraviolet spectrophotometer. Results are that the activities of enzyme SOD in the blood of rats which were fed adding fresh melon and fruit, and the activities of mixed groups is even higher.
