Preliminary studies have been undertaken to evaluate the potential of immobilized phenylboronic acid (PBA) for the solid-phase extraction (SPE) of glucuronide metabolites from urine. These studies have demonstrated that immobilized PBA can be used to specifically extract phenolphthalein glucuronide (5

A method for improving the assay of beta-glucuronidase in hepatic and gallbladder bile is described. The method uses ion-pair extraction with N,N,N-triheptyl-1-heptanaminium bromide to remove pigments and bile acids. Conjugated bilirubin, unconjugated bilirubin, and taurine and glycine conjugates of deoxycholic
