| Abstract: | Bile pigments in the bile of the rainbow trout, Salmo gairdneri, tilapia, Tilapia nilotica, and pejerrey, Odonthetes bonariensis, were analyzed by HPLC and TLC.Major bile pigments of rainbow trout and pejerrey were bilirubin glucuronides and ditauro-bilirubin, respectively. Ditaurobilirubin was not detected in rainbow trout and bilirubin glucuronides were scarcely found in pejerrey. Biliverdin seemed to be the sole bile pigment in tilapia, but it was a minor component in the other fish. These results are in accord with the previous reports in which the diversity of bile pigment composition was demonstrated in some fish. |
