Determination of plant materials elemental composition is a useful tool for modern phytochemical research. The analysis of the element composition of medicinal plant seeds, leaves and roots could provide new data for their biological and ecological assessment. The purpose of the research is a comparative study of the quantitative content of macro- and microelements in the leaves, roots and seeds of some Rumex species (Polygonaceae), R. pamiricus Rech. f, R. conglomeratus Murray, R. confertus Willd, R. aquaticus L. In this work, using the method of ICP-MS analysis the elemental composition of seeds, leaves and roots was studied. As a result for most elements their similarity was noted, which indicates the commonality of the metabolic processes in plants of related species. The macroelements in the seeds, leaves and roots of the studied species, Na, Mg, Al, Si, P, K, and Ca are accumulated in the maximum amount, and of the microelements – Fe. Also, 5,619 mg/kg Pb in R. confertus leaves, 20,726 mg/kg in R. pamiricus seeds, 3,036 mg/kg in R. aquaticus roots, significant accumulation of 10,055 mg/kg was observed in R. conglomeratus seeds and 33,338 mg/kg Bi in R. aquaticus leaves.
