However, the yield of beta-CD-solubilized DPPH radical is less than 1% due to the poor solubility of beta-CD in water. In this study, the beta-CD derivatives, such as 2,6-di-O-methyl-beta-CD (DM-beta-CD), were used instead of beta-CD to improve the solubility of DPPH radical in water. The scavenging rate constants of DM-beta-CD-solubilized DPPH radical by the water-soluble antioxidants were about half as compared with those of beta-cd-solubilized DPPH., SFRBM's 22nd Annual Meeting}, title = {Reactivity of 2,2-Diphenyl-1-picrylhydrazyl Radical Solubilized in Water by beta-Cyclodextrin and Its Derivatives}, year = {2015} }
