The object of research was Crataegus pontica 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 the water-soluble and vitamins was studied by HPLC relative to standard
samples. Chromatographic and structural studies of the aboveground part of the Crataegus pontica
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 Crataegus pontica L.: polyphenols, (+) - catechin, (-) - epicatechin.
