ABSTRACT The effect of adrenalectomy on taurocholic acid, the main bile acid of the rat, was studied. The bile was obtained by cannulation from the ductus choledochus. The concentration of taurocholic acid in the bile was determined using thin-layer chromatography. The taurocholic acid concentration in the bile of the adrenalectomized animals was significantly decreased, being about a half that of the control rats. The results are briefly discussed.

A simple and reproducible method using the non-ionic resin, Amberlite XAD-7, for the isolation of bile acids from serum by a batch procedure is described. Recoveries were greater than 95% for the non-sulphated bile acids and greater than 70% for the sulphate esters of bile acids. By using 1 g of resin, recoveries were independent of the mass (0.1–5 μmol) of the bile acid present. Up to 35 samples a day can be extracted without requiring dedication of the operator. When serum extracts were analysed by the 3α-hydroxysteroid dehydrogenase procedure for estimation of bile acids, virtually all the background fluorescence was eliminated. These extracts were also suitable for gas liquid chromatography, thin layer chromatography, and radioimmunoassay.
