Abstract
Investigations on the antioxidant activity to vitamin A of phenoldisulfides synthesized by the authors indicated that the activity of the compounds tested were generally weak, except thymoldisulfide and mono-t-butyl-p-cresoldisulfide which showed a considerable activity. It was, however, found that these disulfide compounds had the effect for protecting vitamin A from oxidation by removing such metal ions as copper ion promoting the oxidation of the vitamin.
