The chemical components from benzene/ethanol extractives of fresh Phyllostachys heterocycla var. pubescen were separated and identified by GUMS after enriched. Relative content of each component was determined by area normalization. 42 compounds representing 98.29% of the extractives were identified. The main and abundant constituents were as: tetradecane,2,6,10-trimethyl-(7.81%), dodecane (7.39%), indole (7.02%), nonadecane (5.77%), pregn-4-ene-3,20-dione,11,21-dihydroxy-,(11a)- (5.46%), tridecane (5.46%), heptacosane (4.56%), 1,2-benzenedicarboxylic acid, diisooctyl ester (4.68%), quercetin 7.'3',4'-trimethoxy (3.69'%,), octadecane,6-methyl-(3.50%), tetradecane (3.39%), silicate anion tetramer (3.33%), tributyl phosphate (2.88%), dibutyl phthalate (5.22%), 1,2-benzenedicarboxylic acid,bis (2-methylpropyl) ester (2.86%), hexadecane (2.77%), ethyl linoleate (2.71%), pentadecane (2.64%), silicate anion tetramer (2.54%), heptacosane (2.10%), and so on. Most components of benzene/ethanol extractives of fresh Phyllostachys heterocycla var. pubescen are not only abundant and healthy to human, but used as bioenergy.
