ESTIMATION OF THE ELEMENTAL PROFILE OF LEAVES, ROOTS, SEEDS AND DRY EXTRACTS OF ARCTIUM LAPPA AND ARCTIUM TOMENTOSUM

Abstract

The use of plant raw materials can be hindered due to concerns about their quality and safety for the human body, resulting from exceeding permissible limits of radionuclides, heavy metals, and other xenobiotics. Ensuring the quality and safety and guaranteeing the quality of raw materials and finished products is one of the tasks for researchers and practitioners. The composition and content of macro- and microelements in the seeds, roots, and leaves of A.lappa and A. tomentosum, cultivated and growing wild in the Tomsk region (Timiryazevskoye village) and Altai Territory (Altaiskoe village), have been determined, and samples a dry extracts of the roots and leaves of A. tomentosum produced by Visterra LLC, have been analyzed. The elemental composition was determined by using neutron activation analysis and flame photometry. The samples of wild and cultivated species, extracts revealed the presence of 31 chemical elements. According to the potassium content, Arctium lappa and Arctium tomentosum can be attributed to potassium concentrator plants. The leaves, roots, and seeds have the same elemental composition parts of the plant and species. In all samples of roots, seeds, leaves, and dry extracts, the levels of Cd, As complied with the requirements of the standards and sanitary norms.
