Abstract
To create phytomedicines for the treatment of dyselementoses with reproducible pharmacological effects, it is necessary to know within what limits the content of microelements can vary in commercial thickets of herbs. The aim this work was to determine variability of the content of microelements in the underground and aboveground organs of Nonea rossica Stev.The above-ground and underground shoots of the plant was collected on the territory of the Novosibirsk region. The content of plant biogenic elements B, K, P, V, Ca, Cu, Fe, Mg, Mn, Mo, Na, Si, Zn, Ni, Co and toxic elements was determined by mass spectroscopy with inductively coupled plasma. The main statistical parameters – the mean value, the coefficient of variation and confidence intervals were defined and they were analyzed for homogeneity using the Wilcoxon test.As a result of the research, it was found that N.rossica naturally absorbs microelements that are biogenic for the plant organism, which accumulate in the aboveground organs of the plant and their quantitative content have little variability .Exogenous pollution makes a significant contribution to the accumulation of toxic elements and conditionally toxic elements, which leads to a large variability of their quantitative content.
