Supercritical fluid extraction method (SFEm) has been used for the purification of peat cellulose and the extracts were analyzed and determined by gas chromatography-mass spectrometry. Series of methyl esters, ethyl esters and n-alkanes as well as small amount of fatty acids were detected. C_max of long-chain n-alkanes , being typical of odd-to-even carbon number predominance, are at C₂₉, C₃₁, C₃₃. Most of the series of ethyl esters which have not been reported by far have characteristic of a distribution at high carbon number and distinct even-to-odd carbon number predominance. All of this, to a certain extent, discloses the information of climatic condition and variation in the process of the formation of peat.
