Аннотация:Hydrophobic fractions of two mumiyo (shilajit) and one peat samples were analyzed with a use of NMR spectroscopy. Chloroform and ethanol-benzene extractions of the samples obtained after removing of water solutions were analyzed with solution-state 1H NMR, while cross-polarization MAS 13C NMR technique was used for the solid phase study. The study demonstrated that mumiyo and peat samples differed in the structural organization of methilene chains.
