Using gas-liquid capillary chromatography and gas chromatography-mass spectrometry, the content of DDT and its metabolite DDE was determined in 49 official phytopreparations (liquid extracts and tinctures) from yarrow herb, thyme herb, nettle leaves, viburnum fruits and hawthorn
fruits. It was found that the absolute concentration of DDT in liquid extracts and tinctures reached 0.45 ng / g, DDE – 3.07 ng / g. The transfer of toxicants from raw materials to alcohol dosage forms did not exceed 16% for DDT and 68.94% for DDE. With an increase in the concentration of the
pesticide in plant raw materials, its transition to liquid extracts and tinctures decreased. The results
obtained did not exceed the permissible levels of DDT and its metabolites in plant-based dietary
supplements
