Description

1. The photochemical reaction of adenine in the presence of riboflavin was carried out and its nature was discussed.<br> 2. Hypoxanthine was obtained as a photo-product of this reaction, although yield of the product was extremely low.<br> 3. The rate of degradation of adenine in this reaction was enhanced by the presence of thymine.<br> The authors wish to thank Matushita Electric Industrial Co., Ltd., for the supply of fluorescent cadmium borate. The authors would like to express their sincere thanks to Dr. G. Chihara for his discus-sions. Their thanks are also due to Miss Y. Aoki, Miss T. Ono and Miss S. Taniguchi for their assis-tances in carrying out the experiments.
