| 内容記述 | 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical is a water-insoluble stable radical that has been used to evaluate the activity of antioxidants as a reactivity model of reactive oxygen species. In this work, the cyclic voltammetry of the DPPH radical solubilized in water by complexation with beta-cyclodextrin was studied in phosphate buffer solutions (0.1 M, pH 6.0, 7.0, and 8.0). The DPPH radical undergoes a reversible proton-coupled reduction, where the half-wave potential linearly shifts to the negative direction as the solution pH increases. On the other hand, the cyclic voltammogram of the oxidation of the DPPH radical is quasi-reversible, indicating that the oxidized product of the DPPH radical undergoes a chemical reaction. | |||||
