1. The structures of the alpha(2)- and alpha(3)-azopigments, prepared by diazotization of dog bile with ethyl anthranilate, were shown by mass spectrometry and g.l.c. to correspond to azobilirubin beta-d-xylopyranoside and azobilirubin beta-d-glucopyranoside respectively. 2. Both azopigments consist of a mixture
