FIELD: medicine, analytical chemistry. SUBSTANCE: invention can be used in control-analytical laboratories for standardization and control of medicinal agents control. Method involves preparing solutions of a substance and possible impurities to be assayed, chromatography and detection using UV-light. The solution of the analyzed substance is prepared using 95% alcohol and system of solvents acetone 25% ammonia solution in the ratio = 9:0.5 is used as a mobile phase. Method provides the enhanced precision of control for authenticity and purity of xanthinol nicotinate and to exclude using highly toxic reagents. EFFECT: improved assay method. 1 ex 1 ex
