摘要：

Extracts from a peat, a low-rank coal and a bituminous oil shale obtained with liquid carbon dioxide were studied by capillary gas chromatography-mass spectrometry and compared with those obtained by Soxhlet extraction with n-hexane. Although the extraction yields with liquid carbon dioxide were lower, the composition of the extracts, comprising mainly a large variety of linear and cyclic hydrocarbons, was similar in both cases. Owing to the advantages of the liquid carbon dioxide extraction regarding speed, cleanliness and mildness of the extraction conditions, it seems to be an adequate procedure, coupled with gas chromatography-mass spectrometry, to study the biomarker composition of sedimentary organic matter.
