The chemical components of superheated vapour Extractives of fresh Phyllostachys heterocycla var. pubescen were separated and identified by GC/MS after enriched. Relative content of each component was determined by area normalization. 25 compounds representing 97.35% of the extractives were identified. The most abundant constituents were heptacosane (cas) (26.2%) , 14-á-H-pregna (15.71%) , Tetradecane, 2,6,10-trimethyl-(15.55%) , methyl 9,10-difluoromethylene-9-octadecenoate (12.84%) , 1,2-benzenedicarboxylic acid, dibutyl ester (ca...
