COTTONWEED MARSH (MARSH). CHEMICAL COMPOSITION OF ETHANOL EXTRACT
Abstract and keywords
Abstract (English):
For the first time, a detailed study of the chemical composition of ethanol extract of dried marsh (swamp), a product obtained after preliminary exhaustive last ex-traction with n-hexane, toluene, chloroform and acetone was performed. Chromatography-mass spectrometry made it possible to identify 119 individual compounds in this extract with the determination of their quantitative content, mass spectra and structural formulas, and the calculation of the structural-group composition was performed. A characteristic feature of the extract is the presence of significant amounts of nitrogen and sulfur-containing compounds (20.04), esters (21.47), sterols (18.54), carboxylic acids (8.15) and hydrocarbons (7.15) (wt. % of the extract). In addition, the extract contains phenols, ketones, aldehydes, alcohols and glycosides: 5.01; 4.34; 4.88; 3.16 and 3.12 (wt. % of the extract), respectively. Dominance in the extract of nitrogen-sulfur-containing and compounds; environment of sterols-betulin and its derivatives, esters, as well as the presence of different structure of phenols, glycosides, aldehydes and alcohols makes it possible to assume a wide range of pharmacological activity of drugs based on ethanol extract of dried marsh (marsh).
