摘　　要：分别以CS2和甲醇为溶剂，辅以超声波对先锋褐煤进行常温萃取，利用傅里叶变换红外光谱（FTIR）和气相色谱/质谱（GC/M S ）分析萃取物的组成及结构。结果表明，两种萃取物中共检测到124种有机化合物；CS2萃取物中烃类化合物相对含量较高，占CS2萃取物总量的52．08％，从C14～C30（除C23外）烷连续分布；甲醇萃取物中含氧和含氮化合物相对含量较高，分别占甲醇萃取物总量的39．28％和20．95％；此外还检测到多种生物标示物。Xiangfeng lignite was extracted thoroughly with CS2 and methanol under the ultrasonic-as-sistant condition at room temperature ,and the compositions and structural characteristics of the ex-tracts were analyzed by FTIR and GC/MS .The results show that altogether 124 compounds are found in the extracts ,and in CS2 extracts the relative content of hydrocarbon compounds （HCCs） reaches 52 .08% ,which are distributed continuously from C14 to C30 expect for C23 ,while in methanol extracts the relative content of oxygen-containing compounds and nitrogen-containing compounds are compara-tively high ,accounting for 39 .28% and 20 .95% ,respectively .Additionally ,many biomarkers are detected in the extracts .
