Separation of methylated free bile acids from their taurine and methyl glycine conjugates by thin-layer chromatography

Class separation of methylated free bile acids from bile acids conjugated
with taurine and methylglycine was accomplished using a solvent system of
2,2,4-trimethylpentane-absolute ethanol 10:1 (v/v). By developing a silica
thin-layer plate two times with solvent in a Brinkmann sandwich tank, the
difficult resolution between methyl cholate and methyl glycolithocholate
was achieved. Evidence is presented that this separation system may be
useful as a preparative step in the analysis of bile acids by gas-liquid
chromatography or high pressure liquid chromatography.--Bolt, M. J. G.
