Variability of the Trace Element Composition of the Underground and Aboveground Shoots of Nonea Rossica Stev.

Objective: This research goal to evaluate the variability of the contents of microelements in the underground and aboveground organs of Nonea Rossica Steven. Methods: The objects of the study were the aboveground and underground shoots of N. rossica from plants collected during the flowering phase. The contents of microelements were determined by inductively coupled plasma mass spectroscopy. Results and Discussion: The analyzed elements were divided into three groups (1) group 1: biogenic elements B, K, P, V, Ca, Cu, Fe, Mg, Mn, Mo, Na, Si, and Zn and also Ni and Co: group 2: elements having a dominant toxic influence : Ag, Al, Ba, Br, Cr, I, Se, Sn, Sr, Ti and group 3: toxic elements As, Bi, Cd, Hg, Pb, Sb, Te, Th, Tl, and U. It was established that the mean value of the coefficient of variation for the nutrients (group 1) in the aboveground parts of the plants is 27.8%, being significantly lower compared to the group 2 and group 3 elements (44.8 and 50.2%, respectively). At the same time, for the underground organs of the plants, the coefficients of variation for the elements of all groups do not differ significantly, being 41.7, 44.7, and 52.3% for groups 1, 2, and 3, respectively. Conclusions: The revealed patterns allow considering medicinal plant raw materials “Nonea rossicae herba” as a promising source for the creation of phytomedicines with sufficiently reproducibly contents of B, K, P, V, Ca, Cu, Fe, Mg, Mn, Mo, Na, Si, Zn, Ni, and Co to be used for prevention of diselementoses
