Abstract: | Bile acid composition was investigated in normal gallbladder-bile collected from the Japanese patients suffering from the diseases other than hepatobiliary tracts.In addition to cholate, chenodeoxycholate, deoxycholate and lithocholate, ursodeoxycholate was detected as a predominant bile acid in all cases tested and its quantity was higher than that of lithocholate in most cases.A simplified method has been developed for the quantitative determination of bile acids. They were derived to their methyl ester-trimethylsilyl ethers and determined by gas-liquid chromatography on a column of 3% poly-phenyldiethanol amine succinate-80-100 mesh Chromosorb WHP. Average recoveries of added amounts of standard bile acids were found to range from 97 to 100%. |
