β¦ Synopsis
We describe an optimized liquid chromatographic method for simultaneous analysis of 10 conjugated bile acids in gall bladder and ductal bile. A quick and effective one-step purification with Sep-pak C-18 was adopted. We used a reverse phase C18 stainless steel column and an isocratic mobile phase in a flow programme and monitored the column effluent at 205 nm. The within-day CV ranged from 0.3 to 1.8%, and the between-day CV from 1.2 to 7.2%. Absolute analytical recovery ranged from 89 to 107%. Linearity ranged from 0.3 to 3 mg/mL for most bile acids. The chromatographic analysis was completed in 18 min.

A method for the quantitative analysis of unconjugated and conjugated bile acids (BA) in serum of patients with primary biliary cirrhosis (PBC) before and after therapy with antibiotic or ursodeoxycholic acid (UDCA) is described. After separation of the free, glycine and taurine conjugated (F, G and
## Abstract A simple method for quantification of conjugated bile acids in human bile using ^1^H NMR spectroscopy is presented. Bile acids in human bile are essentially conjugated with either glycine or taurine. The amide NH resonances from the conjugated bile acids are invariably devoid of interfe
Major conjugated bile acids of human bile have been resolved by high-pressure liquid chromatography. The elutions are carried out in two stages on Corasil II or PPorasil columns; first, an alkaline solvent system (Zpropanokethyl acetate/ water/7 N ammonium hydroxide, 260:600:50:3) was used for separ
