The paper presents the results of a study of the mineral composition of supercritical carbon dioxide extracts № 1, № 2 and number 3 seed black cumin seed by capillary electrophoresis. According to the research found that in all the carbon dioxide extracts were identified 8 minerals (potassium, sodium, magnesium, calcium, copper, zinc, iron and manganese). The maximum content in the extract macronutrients observed number 2 (2966±78 mg/kg). As regards minerals, the dominating amount of the extract was concentrated in the number 3 (27,3±0,82 mg/kg). When studying the quantitative content of the individual elements, it was found that the number of the extract 2 prevailing amount were found potassium, magnesium and calcium. High concentrations of sodium, zinc and copper were observed in the extract of number 3. Extract number 1 differed from extracts number 2 and number 3 maximum content of iron and manganese. Thus, the results of the study of supercritical carbon dioxide extracts from the seeds of black cumin seed in respect of macro- and micronutrients indicate their degree of enrichment of the most important combinations of minerals
