Abstract: In this article the analysis of ephedrine and verapamyle in forensic-chemical researches with application of thin-layer chromatography and densitometry is considered. Detection limit of ephedrine and verapamyle is 10,0 $\rm \mu$g/ml in a sample. The possibility of ephedrine and verapamyle quantitative determination in model samples in the range of 10,0–250,0 $\rm \mu$g/ml concentration is indicated.

Keywords: ephedrine, verapamyle, densitometry, thin-layer chromatography.
