Thin-layer chromatographic separation of conjugates of ursodeoxycholic acid from those of litho-, chenodeoxy-, deoxy-, and cholic acids
AK Batta, S Shefer and G Salen
Separation of the glycine and taurine conjugates of ursodeoxycholic acid
from those of lithocholic acid, chenodeoxycholic acid, deoxycholic acid,
and cholic acid by thin-layer chromatography is described. Thus, on running
a silica gel G plate first in a solvent system of n-butanol- water 20:3 and
then in a second solvent system of chloroform- isopropanol-acetic
acid-water 30:20:4:1, all the above-mentioned conjugated bile acids are
separated from one another. The application of this method to study the
change in the biliary bile acid conjugation pattern in ursodeoxycholic
acid-fed gallstone patients is described.
