Separation of sulfated from non-sulfated serum bile acids without the use of Sephadex columns.


Methods currently in use for the quantitative measurement of sulfated serum bile acids usually lead to low recoveries. The present technique uses two internal standards and involves enzymatic hydrolysis followed by extraction of the non-sulfated fraction in ether at pH 4.6. The sulfated fraction is then solvolysed before gas-liquid chromatographic analysis… (More)
