Black bamboo, who was considered to have biohealth function in folk, is becoming a major biomass in rooms. Therefore, the chemical components from black bamboo were identified by TD-GC/MS at different temperature. The main components of black bamboo biomass at 300°С were butanal(13.29%) , 3,4-dihydroxyacetophenone (8.80%) , ethene, (2-methoxyethoxy)-( 8.68%), acetic acid, anhydride with formic acid(7.21%) , furfural(6.90%) , 2-cyclopenten-1-one, 2-hydroxy-(6.29%), phenol, 2,6-dimethoxy-(5.67%), etc. And the main components at 320°С were acetic acid(20.87%), benzaldehyde, 2-methyl-(10.96%) , 1,3-propanediamine, n-methyl-(8.72%), phenol, 2,6-dimethoxy-(5.87%), 2-furanmethanol(5.26%), etc. Black bamboo biomass was more healthy to human at 300°С than 320°С. So black bamboo biomass was biohealth function.
