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.

Key words: Abies faxoniana
