Abstract
An unusual pink compound has been isolated from the proteolytic digests of senile nuclear cataract proteins by adsorption onto Sephadex G-10. The tiny amounts obtained precluded definitive structural elucidation, however TLC comparisons show that it resembles triphenodioxazine-1,8-dicarboxylic acid, a pink heterocyclic chemical formed by oxidative condensation of 3-hydroxyanthranilic acid.
