| 摘 要： | 从还原能力、抗脂质过氧化和对不同体系产生的活性氧自由基清除效果等方面对苹果多酚提取物的抗氧化 活性进行了试验研究和评价。结果表明苹果多酚提取物具有较强的还原能力,对脂质过氧化、Fenton反应产生的羟 自由基和光照核黄素及邻苯三酚自氧化产生的超氧阴离子自由基均具有很强的抑制作用或清除作用,且在试验浓 度范围内其最大抑制率或清除率分别可达到94.4％、96.64％、95.19％和90.48％,优于同浓度维生素C的效果或基本 相当。这表明该苹果多酚提取物是一种优良的天然抗氧化剂和自由基清除剂。

| Abstract: | The antioxidant activities of apple polyphenol extracts were studied and evaluated in vitro by determining the reducing capacity, antioxidant activity on lipid-peroxidation, and scavenging effects on active oxygen radicals generated by various system. The results showed that apple polyphenol extracts had stronger reducing capacity, antioxidant activity on lipid-peroxidation, and scavenging effects on hydroxyl radical and superoxide anion radical than ascorbic acid at the same concentration. In the range of test concentration, the maximum scavenging or inhibition rate of apple polyphenol extracts to linoleic acid auto-oxidation, hydroxyl radical generated by Fenton reaction, superoxide anion radical generated by illuminating riboflavin and pyrogallol auto-oxidation system was 94.4%, 96.64%, 95.19% and 90.48% respectively. The results suggested that the apple polyphenol extracts was an excellent natural antioxidant and free radicals scavenger. |
