摘　　要：采用超声抽提法提取了冷杉枝叶的脂溶性物质,经柱层析组族层分离和GC/MS技术,从冷杉脂溶性物质中检测出56种化合物,其中脂肪酸(极性馏分)占到了95.28%.同时在冷杉脂溶性物质中发现一系列萜类化合物(0.156 6 mg/g),该类化合物具有一定的药用和商用价值.通过一系列参数计算,认为冷杉在离株后受到了细菌—微生物的降解作用.The lipid-soluble substances were taken from the leaves and twigs from the firs by the ultrasonic extractiorh Then 56 compounds, 95.28 % of which are mainly fatty acids, were detected out by the column chromatog- raphy and the GC/MS techniques. At the same time the terpenoids（0. 156 6 mg/g）were discovered,which have important medicinal and commercial values. By a series of parameter calculation, we hold that the leaves and twigs could be degraded by some microrganisms when they were taken away from the tree.
