An analytical tobacco sample is treated with an aqueous solution of an organic solvent, the liquid phase оbtained is treated with a water-insoluble organic solvent. The extract obtained is dehydrated by the effect of a water absorption substance and evaporated at a temperature of 40-70°С up to the volume which amounts to 2-5% of the initial volume. The concentrated extract obtained is subject to chromatography and, according to the chromatograms obtained, a conclusion is drawn on the content of organochlorine pesticides in tobacco. A process of chromatography of the concentrated extract obtained is carried out using thin-layer chromatography. Prior to the process of chromatography the concentrated еxtract is additionally passed through a column with a solid sorbent and the purified extract is washed, first, with hexan, аnd then with benzol. The purified concentrated extract is analyzed with the aid of gas chromatography.
