Abstract

Rumex confertus Willd. – sorrel is important in pharmacology and the food industry. It is used in diseases of the gastrointestinal tract, kidneys, as anti-helminth, anti-cyngotic, hemostatic, wound healing, vasoconstrictive, antitumor, in stomatitis, colds, as well as leaves are eaten. Rumex pamiricus Rech. f., is promising for introduction into the culture as a tanning plant. The study of their chemical composition is relevant for determining promising compounds for pharmacology. The purpose of the present work was to study volatile compounds by chromato-mass spectral analysis of essential oil isolated from the above ground part of Rumex confertus и Rumex pamiricus growing in the Republic of Uzbekistan. The dependence of the composition of essential oil on the region of growth of ether carriers, as well as its pharmaceutical value, determined the relevance of this work. As a result of studies carried out in the essential oil of Rumex confertus obtained by hydrodistillation method, 45 components were found, among which 1,2,3-propanetriol, diacetate (1.67%), benzenetanol (3.77%), 5-undecene 1-tridecanol (4.48%), 2-methoxy-4-vinyl High phytol content in Rumex confertus essential oil. allows considering the given plant as a source of this valuable biologically active compound. Fifteen compounds have been identified in Rumex pamiricus essential oil. The dominant components are 2-methoxy-4-vinylphenol (8.24%), nerolidol 2 (8.22%), triacetin (46.69%), cis-jasmone (4.68%).
