SUMMARY. Mineral elements are of great importance for human life, in addition to organic substances. They are the most important catalysts of various biochemical reactions, participate in the processes of growth and development of the organism, and contribute to the adaptation of the organism to the environment. Medicinal plants, as natural sources of mineral complexes, contain elements in a bound form with biologically active substances of organic nature, that is, in a form most accessible to absorption. Therefore, the study of the elemental composition of medicinal plants is one of the mandatory stages of phytochemical research.
The aim – to establish the elemental composition of raw materials of some types of medicinal plants cultivated on the territory of Western Podillia.
Material and Methods. The material for the research was the inflorescences and shoots of sweet lipia, the grass, roots and seeds of the crowned serpia, and the leaves of the large-flowered magnolia.
The determination of the elemental composition of the raw material was carried out by the method of atomic emission spectroscopy with photographic registration on the basis of the Scientific and Technological Complex "Institute of Single Crystals" of the NAS of Ukraine in the Department of Analytical Chemistry.
Results. In the studied types of raw materials of sweet lipia, crowned serpia and large-flowered magnolia, 19 inorganic elements were found – 5 macro-, 10 microelements and 4 ultramicroelements.
The dominant element in all studied types of raw materials is potassium, the content of which is highest in crowned serpia grass and sweet lipia inflorescences – 3400 mg/100 g and 3300 mg/100 g, respectively. Calcium was also found in significant amounts: in crowned serpia grass – 915 mg/100 g, in sweet lipia inflorescences and shoots – 880 mg/100 g and 720 mg/100 g, respectively. A small content of sodium was observed in all types of raw materials.
Among the trace elements in the studied samples, silicon, aluminum and iron dominated. A significant content of silicon and aluminum was found in the inflorescences of sweet lipia and somewhat lower in its shoots (1100 mg/100 g and 640 mg/100 g and 110 mg/100 g and 80 mg/100 g, respectively).
The content of toxic elements in the studied samples did not exceed the maximum permissible concentrations established by the SFU.2.0.
Conclusions. 1. For the first time, the elemental composition of raw materials of a number of medicinal plants cultivated in the territory of Western Podillya was investigated – sweet lipia inflorescences and shoots, crowned serpia grass, seeds and roots, and large-flowered magnolia leaves.
- 19 elements were detected in the studied samples, with potassium, calcium and magnesium dominating the content from macroelements and silicon, aluminum and iron from microelements.
- The results of the study indicate the prospects for studying a number of species of cultivated medicinal plants for the creation of new medicines and dietary supplements based on them.
