【Abstract】 A method for separation of nucleosides and bases was established by high performance liquid chromatography using N _ phenylaminomethyl bonded silica gel(PAMS) as a stationary phase. The effects of variables of mobile phase such as methanol content, ionic strength and pH of phosphoric acid buffer on retention and separation of the analytes were investigated. The fast separation of some nucleosides and bases was accomplished using the column with the stationary phase and 0.02 mol/L K2HPO4 buffer at pH=4 as a mobile phase.更多还原
