Development of a liquid chromatographic method which can separate each of a series of hexopyranosylated cytosine nucleosides from their degradation products formed at acid, neutral and basic pH is described. Both silica-based reverse-phase and polymer columns were examined. Influence of the mobile phase pH, ion-pairing agent, concentration of the buffer and type and concentration of organic modifier were systematically investigated. The concentration of the ion-pairing agent and the buffer were found to have a major effect on selectivity. Samples were finally analyzed on a poly(styrene-divinylbenzene), PLRP-S 100 A (8 microns) 250 x 4.6 mm I.D. column at 60 degrees C and with a mobile phase consisting of acetonitrile-sodium octanesulphonate (pH 2.5; 0.02 M)-potassium phosphate buffer (pH 2.5; 0.2 M)-water (X:25:50:25-X, v/v, where X is variable).
