| Abstract: | A new method that the O2· was produeed by Na2O2 in DMSO/H2O has been reported in this paper. The visible O2· signal can be directly detected by ESR. The conditions of the reaction and.characterization of O2· signal were studied. Scavengingeffect of superoxide anion was investigated with tea polyphenols etc. It is shown that this is an advisable method to produce O2· radical and could be used to look for the new O2· scavenger. |
