title: [Optimization of separation of purine and pyrimidine compounds using ion-pair reversed-phase high performance chromatography (HPLC)].
abstract: Utilization of ion-air reagents in a reversed-phase chromatographic system allows solving a number of problems related to the separation of purine and pyrimidine derivatives. Simultaneous analysis of nucleotides, nucleosides and their bases was carried out by acetonitrile gradient elution using tetrabutyl ammonium phosphate as a counterion in the mobile phase. Besides, optimal conditions were selected for isocratic separation of adenine nucleotides and their metabolites. Furthermore, isocratic separation of certain purines and pyrimidines was achieved by modifying the stationary C18-phase with pentane- and heptane sulphonic acids.
