ELEMENTS OF THE ABOVEGROUND PART OF DATISCA CANNABINA L

Abstract

The purpose of this work is to study the elemental composition of the aboveground part of D. cannabina, and extracts obtained from it using various extractants.Material and methods. The composition of elements in the aerial part of Datisca cannabina L., (Datiscaceae) grown under conditions of introduction and collected in the budding and flowering phases, as well as in extracts obtained from them, was studied byICP-MS.Results. The elemental composition of the aerial part, leaves and stems of D. cannabina is represented by 61 elements. The studied samples do not differ in the composition of elements. In a comparative analysis of the content of elements by organs, it is possible to compose accumulative decreasing series for: leaves - Ca˃ K˃ Si˃ Mg˃ Rb˃ Fe˃ Zn˃ Mn˃ Br˃ Al˃ Ba˃ Cu˃ Na˃ Ti; stems - Ca˃ K˃ Si˃ Mg˃ Fe˃ Zn˃ Al˃ Mn˃ Rb˃ Br˃ Na˃ Ti˃ Cu˃ Ba; herbs - Ca˃ K˃ Si˃ Mg˃ Fe˃ Rb˃ Mn˃ Al˃ Br˃ Na˃ Ti˃ Cu˃ Cr˃ Mo. The elemental composition of extracts obtained from the aerial part of D. cannabina using water and water-ethanol mixtures is represented by 61 elements. The extracts are characterized by a high content of essential elements. The eluting ability to extract elements from raw materials decreases with an increase in the ethanol content in the extractants.
