| 摘 要： | 研究了3种不同溶剂体系提取菜籽饼中植酸粗提液的体外抗氧化性能力。通过Fenton反应体系产生羟自由基(.OH),由连苯三酚在碱性溶液中自氧化反应产生超氧阴离子自由基(O2-.);用分光光度法检测3种植酸粗提液的还原能力及对.OH、O2-.和DPPH.的清除作用。结果表明,3种溶剂提取得到的植酸粗提液都具有还原能力;对羟自由基、超氧阴离子自由基、DPPH自由基也有一定的清除能力。

| Abstract: | The aim is to study on antioxidant activities of phytic acid crude extracts with three solvent extracts from rapeseed meal in vitro.The hydroxyl radical(·OH) is produced through Fenton reaction system,and the superoxide anion radical(O2-·)is produced from self-oixdation reaction in alkalescent solution with the help of pyrogallol,reduction ability and elimination effect on ·OH,O2-· and DPPH· of phytic acid crude extract is measured with spectrophotometry.Phytic acid of crude extracts with three solvent extracts have reduction ability and some elimination effect on hydroxyl radical,superoxide anion radical,DPPH radical. |
