| 摘 要： | 以ABTS自由基清除能力为考察指标,研究不同反应温度和反应pH对蒲公英和葵花籽仁绿原酸抗氧化活性的影响,以抗氧化活性的IC50为复配依据,评价蒲公英和葵花籽仁绿原酸复合物的协同抗氧化作用。结果表明:反应体系pH 6、45℃条件下,蒲公英和葵花籽仁绿原酸对ABTS自由基清除率达到最高,分别为91.78%和90.51%。蒲公英和葵花籽仁绿原酸复配品可提高对ABTS自由基清除效率,具有协同抗氧化作用。

| Abstract: | The antioxidant activities of chlorogenic acid from dandelion and sunflower seeds were studied under different reaction temperatures and pH with ABTS free radical scavenging capacity and FRAP ferrous ion reducing capacity as the indexes.The synergistic antioxidant activities of chlorogenic acid from dandelion and sunflower seeds were evaluated on the basis of IC50.The results showed that the free radical scavenging rate of ABTS by dandelion and sunflower seed chlorogenic acid was 91.78%and 90.51%respectively at pH 6 and 45℃.The compound of dandelion and sunflower seed chlorogenic acid could improve the scavenging efficiency of ABTS radical reducing ability with synergistic antioxidant effect. |
