The photodecomposition of bilirubin and other bile pigments

Abstract

The photodecomposition of bilirubin in chloroform was studied by spectrophotometry and chromatography. A fraction of the pigment decomposed with retention of the tetrapyrrolic structure, giving biliverdin, chrysin, and choletelin. The rest of the bilirubin decomposed to propentdyopents, imides, a pyrrolic acid, and simple aliphatic acids. Verdins, mesobiliviolin, and i-urobilin treated similarly retained the tetrapyrrolic structure for a longer time.
