The chemical components from benzene/ethanol extractive of fresh Phyllostachys heterocycla shavings were separated and identified by GC/MS after enriched. Relative content of each component was determined by area normalization. 73 compounds of the extractives were identified. The main and abundant constituents were as: vitamin E, hexadecanoic acid(cas), 9,12-octadecadienoic acid (z,z)-, tetradecane,2,6,10-trimethyl-, dodecane, indole, dodecane, tridecane, nonadecane, pregn-4-ene-3,20-dione,11,21-dihydroxy-,(11á)-, heptacosane, 1,2-benzenedicar...
