Use of anionic liquid ion exchangers in the chromatography of steroidal glucosidoronic acids

Recovery of steroidal glucosiduronic acids from organic solvents containing anionic liquid ion-exchangers

“…In the preceding paper (Mattox et al, 1972) we reported that certain steroidal glucosiduronic acids can be extracted almost quantitatively from aqueous solutions into organic solutions of liquid ion-exchanger. In other studies, liquid ion-exchangers have been used for chromatography of glucosiduronic acids on micro (Mattox & Goodrich, 1968;Mattox et al, 1970) and preparative scales (V. R. Mattox & J. E. Goodrich, unpublished work). A simple widely applicable batch procedure for removing glucosiduronic acids from an organic solution of exchanger is needed to make it possible to utilize liquid ionexchangers for the recovery of steroidal glucosiduronic acids from urine and after chromatography.…”
