Abstract
The object of research was dioecious nettle (Urticadioica L.). A comparative study of dioecious nettle growing both in mountainous areas and in the suburbs of Tashkent was conducted. For research, the aboveground parts of the plant (leaves and stem) were used. The analysis of micro and macronutrients was performed by inductively coupled plasma mass spectrometry (ICP-MS). the Quantitative content of water-soluble and vitamins was studied by HPLC relative to standard samples. Chromatographic and structural studies of the aboveground part of the Urticadioica L. plant were performed. on the content of phenolic compounds and flavonoids in them. Chromatography-mass spectrometry was used to determine the chemical structure of isolated individual compounds. The results of these analyses suggest the presence of the following classes of flavonoids in the plant Urticadioica L.: flavonols, flavonones and flavonoid glycosides.

Key words: dioecious nettle, macro- and microelements, fraction, two-dimensional paper chromatography, chromatography-mass spectrometry, flavonoid.
