Abstract

The neutral α-tocopheroxyl radicals, generated in monolayers on silica gel containing α-tocopherol and partly autoxidised methyl linoleate at 90°C, were detected and identified by ESR spectroscopy. Addition of ascorbic acid to the monolayer resulted in the complete quenching of the α-tocopheroxyl radical spectrum. This lends support to the view that ascorbate transfers hydrogen to α-tocopheroxyl radicals thus regenerating α-tocopherol.
