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[2.2.1.0(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.
摘要：
Bamboo forest was a dominantly ecological and sustainable economic recources. However, bamboo extractives and hemicellulose were nearly complete dissolved out in preparation of the fiber, this would result in more serious water pollution and meanwhile bring a great waste of biological resources. Thereby. In order to obtain the way to lower the negative impact of the extractives and hemicellulose, the Phyllostachys pubescens biomass was treated in alkaline solutions at room temperature and the extractives obtained was analyzed by SIZER basen on the full-factor method. The results were following as: (1) Sort of alkaline and concentration of alkaline had a significant influence on the leaching rate of particles at 0.01 level. And the optimal concentrations of KOH, NaOH, LiOH were 16.0%, 17.5% and 17.5% at 25 degrees C, respectively. (2) Pretreatment, extraction time and sort of alkaline had no influence on the leaching rate of particles. But the benzene/ethanol pretreatment was valuable and necessary. when 16% NaOH and 17.5% KOH were used, the optimal extraction time were all 16h to untested and tested samples.

摘要：
In order to eliminate colour difference of bamboo sheets, the energy saving technique of bamboo bleaching rapidly based on water resource protection was studied. The results showed that the appropriate addition agent may improve function of H2O2 bleaching bamboo. the oxidation of H2O2 was the best at 80°С. If the temperature was too low or too high, the bleaching effect was bad. And the bleaching solution formula had the influences on bleaching effect. Alkaline bleaching solution formula was better.

Phyllostachys heterocycla, who was considered to have biohealth function in folk, is becoming a major biomass in rooms. Therefore, the chemical components from Phyllostachys heterocycla were identified by TD-GC/MS at different temperature.

摘要：
Bamboo is so easily Mouldy that bamboo products have no high value added utilization. Therefore, the effect of red extractives from 18 plantation woods on bamboo biology moulding was studied based on full-factor test. The results were: (1) The red extractives of plantation could mostly inhibit the growth of Penicillium expansum, but a few could inhibit the growth of Aspergillus niger. (2) The red extractives of Cunninghamia lanceolata bark and shavings, Deodar cedar branch, Eucalyptus dunnii bark, Eucalyptus tereticornis bark, Bagasse, Eucalyptus camaldulensis branch and shaving were the most effective in controlling spore germination of Penicillium expansum, and the one raphiolepsis branch was the most effective in controlling spore germination of Aspergillus niger. (3) The effect of the red extractives from Cunninghamia lanceolata bark and shaving, Deodar cedar branch, cypress branch, Eucalyptus tereticornis branch on bamboo moulding was highly remarkable on outdoor test. So the plantation woods could be used as biologic mould inhibitor for bamboo.
