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 ...
