ABSTRACT. The It is known that the biochemical composition of plants depends on the variety, place of growth, collection time and method of conservation. The microelement profile of plants carries information about the ecological state of the region and the plant itself. The purpose of the study was a comparative study of the composition and ability to accumulate elements in the fruit of sea-buckthorn berries of various types. The analysis and analysis of the elemental composition of the fruit of buckthorn of buckthorn of various varieties, harvested in the Botanical Garden of Moscow State University. M.V. Lomonosov, as well as soil samples from the site of growth. The elemental analysis was carried out by inductively coupled plasma chromatography-mass spectrometry. The similarity of the composition of macro-, micro- and ultramicroelements of fruits of high-quality and wild-growing sea-buckthorn berries is shown. In the investigated objects, the maximum permissible concentrations for Fe, Cu, Zn, Co and Cr, established for vegetables and greens, have been exceeded. The conducted researches testify to the necessity of rationing in the medicinal plant raw materials of the maximum permissible content of not only unconditionally toxic elements (Cd, Hg, As, Pb), but also other potentially hazardous heavy metals. The values of biological absorption coefficients for the studied objects indicate the safety of application of buckthorn berries, since this raw material does not accumulate toxic elements. There were no energy-accumulating elements. Elements such as Zn, Ni, Cu, Mo, Pt, Mg, Ca, K, Au, and W belong to the group of weak accumulation and medium capture. The remaining mineral components found belong to the group of weak accumulation and very weak capture. As a result of the analysis, insignificant differences in the content of mineral components in comparison of fruit of varietal crops and wild-growing sea buckthorn were found out. However, in the studied objects, the maximum permissible concentrations of potentially toxic heavy metals such as Fe, Cu, Zn, Co and Cr established for vegetables and greens, have been exceeded.
