A rapid flexible method has been developed for the quantitative determination of bile lipids In gallbladder and hepatic bile and duodenal aspirates. Quantification of bile salts involves separation of bile salt conjugates from one another and other bile lipids by thin layer chromatography. The separated salts are determined using 3-hydroxysteroid dehydrogenase and gas liquid chromatography. Cholesterol is determined in petroleum ether extracts of saponified bile by application of the Lieberman-Burchard reaction. Phospholipid phosphorus is determined in purified bile lipid extracts by oxidation followed by application of Bartlett's modification of the Fiske- SubbaRow method.
