Abstract:Metabolites of corticosteroids that contain the 21-oic acid moiety are found in human urine. The acids from neutral steroids and urinary pigments have been separated by passing the mixture through a column of polyethyleneimine cellulose. The acids adhering to the column are quantitatively eluted with dilute formic acid. The purified preparation is suitable for derivatization and chromatographic analysis.
Keywords:polyethyleneimine cellulose  steroidal carboxylic acids  urine  corticosteroid metabolites  high-efficiency TLC  class separation of corticosteroid metabolites
