説明

Abstract 1. 1. From the crude extract of the wings of Papilio xuthus labelled with [1-14C]β-alanine, the decomposition-product SN-1 of Papiliochrome II was purified and hydrolyzed. Of two main hydrolysates, one was identified as [14C]β-alanine, and the other was the non-radioactive substance SN-1a. 2. 2. The above results were confirmed by the decomposition of purified Papiliochrome II and by the autoradiograph of thin-layer chromatograms of Papiliochrome II and its decomposition-products. 3. 3. It was also proved using [1-14C]DOPAmine that SN-1a is a DOPAmine derivative. 4. 4. From the previous and present results, it is evident that Papiliochrome II contains, as constituents, both kynurenine and a DOPAmine derivative containing β-alanine.
