Abstract: The chemical components of the essential oil form Abies faxoniana,an endemic species to China,were analyzed by retention indices determinations,authentic sample superimpositions,and GC-MS-DS determinations. The peak areas were calculated with a LCI-100 integrator. Of the 242 components isolated from the essential oil by a 50m×0.25mm i.d.bonded methyl silicone fused silica glass column,50 components which make up 97.12% of the total oil were identified.The major components are limonene(41.53%),α-pinene(22.31%),and camphene(17.87%)etc.

摘要： 岷江冷杉(Abies faxoniana Rehd．et Wils．) 为我国特有树种[1],以产于四川省岷江流域而得名，是岷江中上游、白龙江上游和大小金川流域的主要森林树种，拥有较大蓄积量。其针叶富含精油，但至今未加以任何利用，其化学组成也未见报道。为了使这一资源得到合理利用，我们对岷江冷杉精油的化学成分进行了研究.
