Separation of prostaglandin metabolites on sephadex LH 20 columns.

Sephadex LH 20 columns have been investigated for the separation of initial prostaglandin metabolites. Solvent systems are described for the separation of the free acids of 15-keto-dihydro-PGE1, 15-keto-PGE1, PGE1, and PGF1alpha. Further, one of the solvent systems is described for the separation of pulmonary metabolites of PGE1 and PGF1alpha, and another one for separation of dihydro-PGE1 and PGE1.
