| 摘 要： | 测定了14种鲜榨果汁中黄酮和VC的含量,通过果汁对羟自由基、超氧阴离子自由基和过氧化氢的清除试验,比较了其抗氧化性能的强弱。结果表明,抗氧化性由高到低顺序依次为猕猴桃、草莓、橘子、木瓜、橙子、柠檬、苹果、蜜柚、杨桃、梨、枇杷、芭乐、西瓜、菠萝。鲜榨果汁中黄酮含量与其抗氧化性之间有显著的相关性。说明鲜榨果汁的抗氧化性能主要是由含有的黄酮类化合物决定的。

| Abstract: | 14 kinds of juice are selected to determine the content of flavonoid and VC. The antioxidant activity of juice is evaluated by measuring the clearing ability of hydroxyl free radical, superoxide anion free radical and hydrogen peroxide. In decreasing order of antioxidant activity of juice is actinidia, strawberry, citrus, papaya, orange, lemon, apple, honey pomelo, carambola, pear, loquat, guava, watermelon, pineapple. The results show that the juice flavonoid content and the antioxidant activity correlates significantly. It is suggested that the antioxidant activity of juice is mainly decided by flavonoid content. |
