Abstract
Different groups of organic compounds were specified in hexane-chloroform extract of fuscum peat and Sphagnum hollow peat retrieved in Bakcharsky bog that is situated in Tomsk region. Organic components were identified in native peats taken from a depth of 40-60 cm in elevated (pine-shrub-Sphagnum bog) and low (sedge-Sphagnum lawn) mire landscapes, and after their field decomposition in the same ecosystems during 16 months above and below the water table, at depths of 5-10 cm and 25-30 cm. The analysis of peat extractive compounds was carried out by gas chromatography-mass spectrometry. The total content of all extractives was 309 μg/g abs. dry matter in Sphagnu...
