    Electron spin resonance (ESR) was used to investigate the reaction of aspirin toward reactive oxygen species, such as hydroxyl radicals (·OH), superoxide radicals ( O2 - ) and H2O2. The Fenton reaction (Fe(II) + H2O2 ---> FE(III) + -OH + OR) was used as a source of -OH radicals. The results show that aspirin is an efficient -OH radical scavenger wi ...
