Abstract. Macro– and trace elements play an important role in biological processes, connected with malignant tumors emergence and development. Despite numerous data on elemental composition of tumour tissues up to date, the effect of plant preparations on elemental composition of tumors has been poorly investigated. In order to evaluate the elemental composition of mice Lewis carcinoma tumors under Artemisia dracunculus (tarragon) and Pastinaca sativa (‘black parsnip’) ethanolic extracts ingestion and to characterize mineral content in the above herbs, ICP–MS– method was used. The results demonstrated significant decrease of Сd, Pb, Hg, Al, Mn, Sr and Se concentrations in Lewis carcinoma tumors of mice under tarragon and ‘black parsnip’ ethanolic extracts loading compared to control group of mice without supply of herbs extracts. ‘Black parsnip’ and tarragon extracts also increased the concentrations of Ca, Si and V in tumors. Contrary to tarragon extract, which increased I content in tumors, ‘Black parsnip” significantly decreased the accumulation of I. Taking into account the anti–carcinogenic and anti–metastatic effects of ‘black parsnip’ and the pro–carcinogenic effect of A. dracunculus, their utilization in preventive medicine is supposed to arise interesting prospects.
