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.
2,2-二苯基-1-苦基肼自由基（DPPH˙）通过β-环糊精（β-CD）成功溶解于水中。由此获得的DPPH˙/β-CD被证明是评估水溶性抗氧化剂（如抗坏血酸盐和Trolox）在水性缓冲溶液中抗氧化活性的有力工具。
