MACRO- AND MICROELEMENT COMPOSITION OF THE HERB AND ROOTS OF HAPLOPHYLLUM DAURICUM (L.) G. DON.

Abstract

Haplophyllum dauricum is a rich source of lignans with antitumor activity. It has been actively used in the practice of Traditional medicine. In addition to lignans, the chemical composition of the species is represented by coumarins, flavonoids, alkaloids and essential oils. However, the composition of the elements of the species, which are necessary for the development of quality criteria of medicinal plants, has not been studied before. In this regard, the purpose of the work was to study the content of macro- and microelements in the aboveground and underground parts of Haplophyllum dauricum of the flora of Buryatia and Transbaikal territory. The content of the following elements was determined by inductively coupled plasma atomic emission spectrometry: Li, Be, Na, Mg, Al, P, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Zr, Mo, Cd, Sb, Te, Ba and Pb. The content of Hg was determined by the "cold steam" method using an atomic absorption analyzer. According to the obtained data, Haplophyllum dauricum is a rich source of calcium, potassium, magnesium and phosphorus, which were dominant. Among the microelements, iron and titanium were in highest concentration, which were accumulated mainly in the underground part of the plant. The content of heavy metals did not exceed the maximum permissible concentration established by the State Pharmacopoeia of the Russian Federation.
