Plantations have been planted in large area in South China now. A mass of leaves was naturally abandoned and degradable so that the resources were wasted. Therefore, in order to make full use of the leaves resources, the effect of bioactive substance in leaves on bamboo biomass moulding was studied based on full-factor test. The result is: (1) Tree species of leavies extractives had highly obvious...
Lignincellose fiber was one of special fibers which were used for textile fiber, paper, engineering plastics, etc. And Eucalyptus camaldulensis has been widely planted in south China. Therefore, based on the single-factor method, the fresh Eucalyptuscamaldulensis wood flour were treated by means of the alkali liquor extraction to obtain the best purification of lignincellose fiber. The results are...
As one of the most expensive wood trees, Ormosia henryi has been planted more than 1000 mu in South China now. A mass of Ormosia henryi leaves was naturally abandoned and degradable so that the resources were wasted. Therefore, in order to overcome the negative effects, Py-GC/MS was used to analyze the extractives of Ormosia henryi leaves. Relative content of each component was determined by area...
Phyllostachys heterocycla is mainly used for pulping. But water and other chemical aids are severely wasted because the content of extractives is high. What's worse, water pollution from the extractives is very serious in South China. Therefore, the acetone extractives of Phyllostachys heterocycla chips were identified by Py-GC/MS. The acetone extractives contains 80 compounds namely lupan-3-one (8...
The resin in Chinese-fir (Cunninghamia lanceolata), which has been widely planted in south China is very liable to bring about the occurance of both holes and spots in paper, to aggravate the pollution of waste water, to shroten the fixed number of service year of equipment, to increase the consumption of chemicals, to relieve the rate of delignification, and to reduce the the permeability of flows...
Bamboo has been used to heal some diseases in the Chinese Folk for a long time. In order to explore widely the potential as the biomedicine utilization, the determination of the chemical components from the five-year-old Dinochloa puberula McClure in South China was carried out by means of Py- GC/MS. The results indicated that the main chemical components in Dinochloa puberula were carbon dioxide(46...
