Abstract

A 2,2-diphenyl-1-picrylhydrazyl radical (DPPH˙) was successfully solubilised in water by β-cyclodextrin (β-CD). DPPH˙/β-CD thus obtained was demonstrated to be a powerful tool to evaluate the antioxidative activity of water-soluble antioxidants, such as ascorbate and Trolox, in aqueous buffer solutions.
