摘　　要：用气相色谱－质谱联用仪对吉林舒兰褐煤蜡树脂和云南寻甸褐煤蜡树脂，进行了生物标志化合物的研究。结果指出，三萜类化合物中含有四环三萜、五环三萜、芳香五环三萜和含氧化合物，其中以Ｃ２５Ａ，Ｂ，Ｃ，Ｄ环－四芳鸟散烷和Ｃ２５Ａ，Ｂ，Ｃ，Ｄ环－四芳奥利烷含量最高，舒兰树脂中这两种化合物的含量高于寻甸树脂约１０倍；The chemical composition of some biomarker compounds in resins of the brown coals from both provinces Ji Lin and Yun Nan are studied The biomarker compounds include 2-methyl alkanes (C15C27), penta-methyl and haxamethyl alkanes, cyclic terpanes such as dicyclic terpanes 8(H)-drimane, 8(H)-homodrimane and methyl-drimane, tricyclic diterpanes (norisopimarane, dihydrorimuene and 16(H)-phyllocladane), tetracyclic triterpanes (dammar-13(17)-ene) and pentacyclic triterpanes (C32-bishomohopane, C33-trishomohopane, C34-tetra-shomohopane and C35-pentashomo hopane) The aromatic tricyclic terpane compounds contain simoneillite, norsimoneillite, retene and C20, B-ring-monoaromatic-diterpane The aromatic tetracyclic terpanes are C21, triaromatic-de-A-ursane and C27, triaromatic-8,14-seco-ursane C28, A-ring-monoaromatic pentacyclic triterpane C25,A,B,C,D-ring-tetraaromatic-ursane and C25,A,B,C,D-ring-tetraaromatic-oleanane In addition, friedelin, 3-oxoallobetulane friedoolean-6-ene and friedoolean-7-ene compounds are present in both resins The amounts of C25,A,B,C,D-ring-tetraaromatic-ursane and C25A,B,C,D-ring-tetraaromatic-oleanane in Shu Lan resin are higher than that in Xin Dian resin The contents of friedelin and 3-oxoallobetulane are also dominate in the Shu Lan resin
