アスコルビン酸の分解に関する研究 : (I)過酸化水素によるアスコルビン酸の分解

抄録

As an initial step to the study of the metabolic system of ascorbic acid in animals and plants, L-ascorbic acid was oxidized by hydrogen peroxide in alkali solution and the products were isolated as crystals or derivatives and also observed by the paper chromatography. As decomposition products, L-threonic acid, oxalic acid, glyceric acid, glycolic acid, formic acid and carbon dioxide were obtained but no furfural and its homologues were detected. The decomposition mechanism of ascorbic acid was, therefore, supposed as indicated in Figure 4.
