n-Alkanes and n-Alkan-2-ones as Lipid Biomarkers of High-Moor Peats and Marsh Plants in Western Siberia

摘要

Comparative analysis of the composition of lipid biomarkers (n-alkanes and n-alkan-2-ones) in sphagnum mosses, herbaceous plants, heather dwarf shrubs, and peats of high bogs of Western Siberia was carried out by gas chromatography-mass spectrometry. It was shown that different marsh plant species differ in ratios between long-chain n-alkanes, and this fact makes it possible to diagnose the source of these compounds in peat. It was found that sphagnum peats occurring in high bogs formed in different natural and climatic conditions differ in the distribution of n-alkan-2-ones, which can be used for the reconstruction of paleoclimatic conditions.
