摘要: 采用格里斯试剂比色法、邻苯三酚自氧化法、Fenton法研究苹果渣中多酚物质的抗氧化活性。结果表明:在实验浓度范围内,多酚提取物对O2·、·OH和NO2-的清除率分别高达97.56%、95.65%和76.98%,说明苹果渣中多酚物质对自由基有较强的清除作用,苹果渣是良好的抗氧化剂资源宝库。

Abstract: In this article, polyphenols in apple pomace were tested for their radical-scavenging by measuring their capacity to scavenge superoxide anion radicals generated by a pyrogallol autoxidation system, hydroxyl radicals generated by Fenton reaction and nitrite. The result indicated that the inhibition percentage of polyphenols against O·2,· OH and NO2-reached-97.56%, 95.65% and 76.98% respectively. The polyphenols in apple pomace were good oxidant inhibitor with strong free-radical-scavenginga ction.

Key words: apple polyphenols, antioxidation, radical-scavenging
