| Abstract: | The scavenging effects of five xanthones on superoxide radicals(O_2·) and hydroxyl radicals((·OH)) has been studied by fluorescent kinetic analysis.The O_2-· were produced by autoxidation of pyrogallol and ·OH were produced by the reaction of fenton,five xanthones was added to the two system solutions,the produced rate of O_2-· and ·OH was reduced.Results showed five xanthones have the scavenging effects on O_2· and ·OH.The relations between structure of xanthones and its antioxidative activities has been explored. |
