The chemical components from superheated water 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. 31 compounds representing 99.99% of the extractives were identified. The main and abundant constituents were as: heptacosane (35.37%), 2,2,4-trimethyl-3- (3,8,12,16-tetramethyl-heptadeca-3,7,11,15-tetraenyl)-cyclohexanol (16.25%), isochiapin B (12.24%), tetradecane, 2,6,10-trimethyl- (cas) (7.59%), dibutyl phthalate (5.66%), etratriacontane (cas) (4.89%), 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester (cas) (3.74%), phosphoric acid, tributyl ester (cas) (2.92%), silicone polymer (2.47%), silicate anion tetramer (2.43%), 2,3-dihydro-benzofuran (2.01%), quercetin 7,3',4'-trimethoxy (1.04%), 1-heptatriacotanol (0.98%) and so on. Most components of superheated water extractives of fresh Phyllostachys heterocycla are abundant and healthy to human, indicating that there are natural health elements in Phyllostachys heterocycla.
