摘　　要： 用柱色谱分离、ＧＣ／ＭＳ分析云南先锋和金所褐煤甲苯（或二甲苯）超临界流体抽提（ＳＣＦＥ）产物油段分中芳烃馏分的组成结构，鉴定出联苯、联苄型结构及它们的烷基衍生物为主要组成部分，菲、芴、芘、荧蒽、苯并芘等多环缩合芳烃的量较少，有较丰富的芳构化五环萜类，包括从三环至五环芳构化的化合物。这些结果反映了多环芳烃成煤过程中的演变情况，可为煤化学研究提供重要的信息。 The aromatic fractions of supercritical fluid(SCF)extracts of Xianfen Ligniteand Jinsuo Lignite from Yunnan Province were characterized by chromatographic separationcombined with GC/MS technique. The results showed that biphenyl, bibenzyl and theiralkvl substitued derivatives were the main components of these aromatic fractions; Polynu-clear aromatic hydrocarbons (PAHs)such as phenanthrene , fluorene,pyrene, flurantheneand benzopyrene were presented in small amount. In addition, a large number of aromaticpentacyclic triterpenoids which contained 3 to 5 rings aromatized compounds were also de-tected. This fact indicated the geochemical mechanism for the conversion of natural triter-penoids into PAHs,it could provide some important informations on coal science.
