Abstract:
The superoxide anion radical (Of) produced in the alkaline dimethyl sulfoxide (DMSO) system was directly measured by electron paramagnetic resonance (EPR) at low temperature. This reaction was used as a model system for generating O2-. Astragalus membranaceus, Codonopsis pilousla, Paeonia laetiflora, Angelica sincnsis and Sophora flavescens, traditional natural medicines which have the effect of delaying anility, were added into the model system to observe their intensifying or inhibiting effect on EPR signals of O2. These results suggest that these traditional natural medicines have the mostly eliminating effect on Of produced in the alkaline DMSO system.
