Influence of pH on Hydroxyl Radical Scavenging Ratio by Gingerol

In this paper, the work was mainly studying influence of pH on Fenton reaction and gingerol scavenging hydroxyl radical. The antioxidant activity of gingerol was characterized by the scavenging hydroxyl ratio and scavenging hydroxyl ratio was analyzed by the spectrophotometry. Hydroxyl radical was produced by Fenton reaction. In the experiment pH and buffer solution have influence on the scavenging hydroxyl radical and Fenton reaction. Gingerol exhibits a strong scavenging radical activity for hydroxyl radical (OH.). The scavenging hydroxyl radical of different extractions of ginger oleoresin is different.
