The component composition of bitumen obtained from brown coal of grade 1B of the Tyulganskoye deposit of the South Ural basin was investigated using destructive O-alkylation with n-butanol. The positive effect of alkylating treatment on the bitumen yield is shown. A number of individual compounds were identified by gas chromatography-mass spectrometry in the composition of the studied bitumoids: n-Tetracosanol-1, Docosanoic acid, Tricosanoic acid, Podocarpa-5,8,11,13-tetraen-7-one, 13-hydroxy-14-isopropyl, etc. Among the identified substances, biologically active substances are present in significant concentrations: β-Sitosterol, gamma-Tocopherol, Sugiol, Behenic alcohol, etc.
