  Solvolysis of chenodeoxycholic acid sulfates

  摘要：

  Chemical solvolysis of chenodeoxycholic acid sulfates was studied using 4 published methods. Quantitative recovery of chenodeoxycholic acid from the 3-sulfate was obtained with each method. However, only 2 methods yielded chenodeoxycholic acid after solvolysis of the 7-sulfate. In each instance a compound resembling lithocholic acid by GLC but identifiable as a derivative of chenodeoxycholic acid by mass spectrometry was obtained and represents a product formed during solvolysis. Failure to obtain adequate solvolysis of chenodeoxycholic acid 7-sulfate can lead to false identification of monohydroxy bile acids and apparent absence of th 7-sulfate and disulfate esters.

  A method for determining in a sample, by liquid chromatography/mass spectrometry, the presence, absence, or amount of one or more or a plurality of analytes is described. The method comprises subjecting the sample to an ionization source under conditions suitable to produce one or more ions detectable by mass spectrometry from each of the one or more of the analytes; measuring, by liquid chromatography/mass spectrometry, the amount of the one or more ions from each of the one or more analytes; and using the measured amount of the one or more ions to determine the presence, absence, or amount of each of the one or more or plurality of analytes in the sample.
