Properties of several reductones as antioxidants for the oxidation of vitamin C were studied and the following results were obtained.1) The strengths of their activities as antioxidants were as follows : (a) the reductones having straight chanin such as triose reductone and D-araboascorbic acid, had a strong antioxidant activity in acidic medium, but very weak in alkaline medium, (b) on the other hand, reductones from polyphenol system such as quercetin, rutin and tannin, exerted stronger antioxidant action in alkaline than in acidic medium, (c) catechol and gallic acid were also active as antioxidants and gallic acid was stronger than catechol in acidic as well as alkaline madium, although its action was weaker than the other substances mentioned above.2) The effectiveness of these antioxidants used in combination was more remarkable than what was used singly. Therefore, these reductones will advantageously be applied in combination.3) Enediolic structure of these substances plays most important part in exerting antioxidant activity, which is dependent greatly upon the number of enediolic hydroxyl groups in a molecule in the case of aromatic reductones.
