| 摘 要： | 目的]对枣核黄酮类物质的抗氧化性质进行研究。方法]将枣核黄酮类提取物加到新鲜菜籽油和猪油中,研究其抗氧化性能;并测定了其对氧自由基、DPPH自由基和羟基自由基的清除率。结果]枣核黄酮类提取物对菜籽油及猪油均有一定的抗氧化作用,在一定添加范围内其作用具有剂量效应关系;柠檬酸、Vc对枣核黄酮类提取物抗氧化效果均有一定的增效作用;枣核黄酮类提取物对超氧阴离子自由基、DPPH自由基和羟基自由基均有较好的清除能力,且随着黄酮类物质溶液浓度的增大,清除能力逐渐增强。结论]该研究结果为进一步综合开发利用红枣资源提供理论依据。

| Abstract: | Objective] The aim was to study on the oxidation resistance of flavonoids in Chinese jujube stone.Method] The extract of flavonoids from Chinese jujube stone was added to fresh rapeseed oil and lard to explore the oxidation resistance of flavonoids;the removal rates of it to O2-·,DPPH· and ·OH were also studied.Result] The flavonoids from Chinese jujube stone had good oxidation resistance on rapeseed oil and lard,and the effects showed dose-dependent;citric acid and vitamin C appeared synergistic effects to the flavonoids;in free-radical reaction experiment,the flavonoids from Chinese Jujube stone also showed strong scavenging ability on O2-·,DPPH· and ·OH,in addition,the scavenging ability increased with concentration increasing.Conclusion] The result of this study had provided theoretical basis for the further development and utilization of Chinese jujube resource. |
