Abstract
The data of the group and component composition of the ethanol extract of brown coal from the Tulgan deposit of brown coal in the South Ural basin are presented. It is shown by means of liquid chromatography, 13C NMR (CPMAS) spectroscopy, FT-IR spectroscopy, gas chromatography-mass spectrometry (GCMSD) that the extract contains: saturated and unsaturated hydrocarbons, alcohols, aromatic compounds, carboxylic acids and phenols. The following biologically active substances have been identified: 1-docosene; gamma-tocopherol; octadecanoic acid; ferruginol; eicosane; sugiol; beta-amyrin, concentrated mainly in the nonsaponifying fraction of the ethanol extract
