  • Title: Determination of conjugated bile acids in human bile and duodenal fluid by reverse-phase high-performance liquid chromatography.
    Author: Bloch CA, Watkins JB.
    Journal: J Lipid Res; 1978 May; 19(4):510-3. PubMed ID: 659989.
    Abstract:
    A simple mehtod using reverse-phase liquid chromatography is presented for resolution and quantitation of the major conjugated bile acids of man, including the glycine and taurine conjugates of the dihydroxy bile acids, chenodeoxycholic and deoxycholic acid. Using modern, high-performance chromatographic equipment, analysis time is less than 30 minutes. The quantitative range of the method, with detection by refractive index, is 0.05 to 0.1 mumol of bile acid and the limit of detection for an injection sample is 0.01 mumol. This provides a sensitivity sufficient for analysis of dilute duodenal and gallbladder bile with minimal sample preparation.
