摘要: A method of purifying cytidine diphosphate choline, which comprises contacting a cytidine diphosphate choline solution containing a nucleic acid analogue and having a pH of not less than 0.5 and not more than 5.0 with an H-type strongly acidic cation exchange resin, and eluting cytidine diphosphate choline adsorbed onto the resin with water or an aqueous solution having an ion concentration of not more than 0.1 mol/L to separate and purify the cytidine diphosphate choline.
