The elemental composition of Hypericum perforatum plants sampled in environmentally different habitats by the example of West Siberia

Abstract

Medicinal plants can amass chemical elements in their tissues due to their ability to tolerate potentially toxic ions in the environment. The Hypericum perforatum L. plants were cultivated in three regions of West Siberia (Kemerovo, Novosibirsk, Kam­ lak Village (Altai Republic)). Elemental analysis was conducted by atomic emission spectrometry. Chemical elements extractable with 10% HCl were assayed by atomic absorption spectrometry. The concentrations of Co, Ni, Cu and Zn have been relatively stable. The coefficients of biogeochemical mobility of Cd, Cu and Zn had high rates, which confirm the possibility of accumulation of these elements in H. perforatum. The concentration of chemical elements in extracts (10 % HCl) was increased as well as their total contents, the degree of extraction was highest for K, Ni, Fe, Cu, Mn, Mg (90 % or more), the minimum for Na (20–40 %) and significantly changed in environmentally different habitats.

“…The National Security and Development Strategies provide an effective policy framework for environmental protection. The directive includes large-scale environmental surveys on the content and forms of various conventional and emerging pollutants along with the assessment criteria for their comprehensive reconnaissance [1]. Efficient management of natural and anthropogenic system contamination with hazardous pollutants is among the most severe challenges of the 21st century [2][3][4][5][6].…”
