FIELD: medicine. SUBSTANCE: method involves preparing solutions of tested sample and solutions of reference substances. Chromatographic examination is carried out in thin sorbent layer. Silica gel is used as fixed phase and a set of solvents is used as movable phase having water purified with 25% ammonia solution in 100:1 proportion for checking phosphadene purity and having water - 25% ammonia solution - glacial acetic acid in 100:0.25:0.5 proportion for checking adenosine purity. EFFECT: enhanced sensitivity of analysis; accelerated method.
