【 摘 要 】

The paper studies the composition of lipid organic compounds of peat from the northern regions of the Russian Federation. Peat was sampled in the northern taiga, forest-Tundra and tundra zones, characterized by various hydrothermal conditions and vegetation cover. n-Alkanes, fatty acids and their ethers, aldehydes, ketones, alcohols, tocopherols, squalene, bi-, tri-and pentacyclic terpenoids, as well as steroids were identified in peat lipids by gas chromatography-mass spectrometry. The dependences of the total content of lipids and the majority of the investigated compounds classes on the ambient temperature and vegetation, as well as the correlation between the composition of n-Alkanes and humidity were revealed.
