Propentdyopentに関する研究 第1篇 Bilirubinよりpropentdyopentへの分解過程について

The photometric observation was mainly done on the decomposition process of bilirubin to propentdyopent under various conditions. And the results were as follows. 1. The propentdyopent (soluble in ether) prepared from bilirubin by the method of v. Dobeneck displayed the absorption maximum at 283 mμ. 2. On the action of Ascorbic acid and H(2)O(2) to bilirubin. the formation of propentdyopent was increased with the dosis of H(2)O(2) under both of aerobic and anaerobic condition, but the absorption maximum as the intermediate product of the reaction was not identified at that time. 3. The progress of reaction was not observed on the action of only ascorbic acid to bilirubin. 4. Standing bilirubin-soda-salt in the buffer of pH 8.04, it resolved into propentdyopent under only aerobic condition. 5. The decomposition of bilirubin to propentdyopent is expected by the oxidation as it is.
