MICROELEMENT COMPOSITION OF PATRINIA SCABIOSIFOLIA AND PATRINIA RUPESTRIS

Abstract

Anthropogenic activity leads to an increased content of trace elements in environmental resources: air, water, land and biota. The accumulation of elements is influenced by the properties of the element, the characteristics of the environment, and the factors of the host organism. This necessitates monitoring of plant materials, especially in regions with a significant raw material base of medicinal plants, but actively exposed to anthropogenic impact, which currently includes the Russian Far East. The article presents the results of studying the elemental composition of plant raw materials of Patrinia rupestris and Patrinia scabiosifolia. It has been established that P. rupestris raw material contains 11-12 elements, P. scabiosifolia raw material contains 11-14 elements, depending on the habitat, 8 of them are essential, 4 are conditionally essential. The homogeneous elemental composition of the grass and roots of P. rupestris and P. scabiosifolia reflects the genetic closeness of the studied species. For most elements, both species exhibit the properties of moderate accumulation and strong capture. Mn, Cr, Ni maintain a constant concentration throughout the range, both for P. rupestris and P. scabiosifolia. Foliar uptake of Co, Br for both species, and Ba for P. rupestris was noted. For P. rupestris and P. scabiosifolia, an acropetal type of element accumulation is noted in Primorye; in the mainland areas of the ranges, a reverse strategy of element accumulation is observed.
