Abstract:

The nitroxides belong to stable free radicals which are widely used for spin labeling in ESR technique. Recently studies showed that nitroxide stable radicals demonstrate effective antioxidative activity in various biological systems ranging from molecular, cellular and laboratory animal level^[l]. But up to now there isn't reported about antioxidant activities on oil of nitroxides. Because antioxidants on oil play a very important role in the food industry^[2], therefore we want to utilize nitroxides as more effective antioxidants in the food industry.
