摘要：

Aromatic components of extracts obtained from four low rank coal samples were investigated by gas chromatography-mass spectrometry. A number of compounds were observed for the first time. The tricyclic aromatic hydrocarbons were investigated in detail. They show close similarities in structure to those reported to be formed in laboratory dehydrogenation experiments. The co-occurrence of molecules in the same samples containing additional unsaturation as well as the aromatic ring(s), offers strong support for the hypothesis of progressive aromatization of diterpenoids. A hypothetical diagenetic pathway is proposed to explain the generation of many of the compounds present. In the pathway the following reactions were considered: aromatization (i.e. dehydrogenation), elimination of substituents, methyl shift, isomerization and side chain shortening of fully aromatized species.
