Black bamboo is becoming a major biomass in rooms. Therefore, the chemical components from black bamboo were identified by TD-GC/MS. The main function components of black bamboo biomass at 40°С were acetic acid(24.71%), 1,1,1,5,7,7,7-heptamethyl-3,3-bis(trimethylsiloxy)tetrasiloxane(17.58%), 1h-indole-2-carboxylic acid,6-(4-ethoxyphenyl)-3-methyl-4-oxo-4,5,6,7-tetrahydro-, isopropyl ester(16.85%), cyclooctasiloxane, hexadecamethyl-(15.28%), cyclotrisiloxane, hexamethyl-(4%), etc. And the main function components at 50°С were acetic acid(40.39%), 1,1,1,5,7,7,7-heptamethyl-3,3-bis(trimethylsiloxy)tetrasiloxane(24.47%), octasiloxane,1,1,3,3,5,5,7,7,9,9, 11,11,13,13,15,15-hexadecamethyl-(16.39%), bicyclo[2.2.1]heptan -2-one, 1,7,7- trimethyl-, (1s)- (3.73%), tricyclo[18.104.22.168(2,6)]heptane, 1,7-dimethyl-7-(4-methyl-3-pentenyl)- , (-)-(3.57%), etc. Black bamboo biomass was more healthy to human at 40°С than 60°С. So black bamboo biomass was fit to use in rooms.
