| 内容記述 | A stable radical, 2,2-diphenyl-1-picrylhydrazyl (DPPH), frequently used as a reactivity model of reactive oxygen species, was successfully solubilized in water by forming an inclusion complex with beta-cyclodextrin (b-CD), but the yield was less than 1%. When b-CD was replaced with 2,6-di-O-methyl-beta-cyclodextrin (DM-b-CD), the solubility of DPPH in water improved significantly. However, the reactivity of DM-b-CD-solubilized DPPH toward water-soluble antioxidants, such as ascorbate, Trolox, and caffeic acid, was significantly lower than that of b-CD-solubilized DPPH due to the steric hindrance of the methyl groups in DM-b-CD. Therefore, b-CD-solubilized DPPH is suitable for evaluating the innate activity of water-soluble antioxidants. | |||||
