ResumoThe influence of oxygen during the reaction of dl-α-tocopherol and polyunsaturated lipids was monitored by ESR spectroscopy and chemiluminescence analysis. Suppressing the oxygen supply to the reaction mixture by sealing the sample tube drastically decreased the kinetics of the radical reactions between the antioxidant and the lipid. These radical reactions could in turn be accelerated by reoxygenation of the reaction mixture.
