The study of antioxidant effects on the autoxidation products of substrates is very important in elucidating the autoxidation reaction mechanism. In this report, the antioxidant effects of tocopherols on the autoxidation products of methyl linoleate were discussed. Results from analyses of the various autoxidation products from linoleate samples with and without tocopherols showed that the addition of tocopherols did not alter the original autoxidation mechanism of methyl linoleate. However, tocopherols did retard the formation of autoxidation products, derived from methyl linoleate samples, according to their individual antioxidant activities. Therefore, that the antioxidant activities of tocopherols were in the order of α-<γ-<δ-T did not result from the difference of the autoxidation products among methyl linoleate samples with and without added tocopherols.
