Magnolia heptapeta has been used in traditional Chinese medicine. However Magnolia heptapeta are still underutilized and hence wasted. In order to better utilize Magnolia heptapeta resources, the biomedicine resource of benzene/alcohol extractives from Magnolia heptapeta leavies were analyzed by GC/MS. The main ingredients of benzene/alcohol extractives of Magnolia heptapeta were toluene, 1,3-dioxane,...
The benzene/alcohol extractives from Artocarpus lingnanensis Leavies have inhibitory effects on bamboo moulds. However Artocarpus lingnanensis leavies are still underutilized and hence wasted. In order to better utilize Artocarpus lingnanensis leavies resources, the biomedicine resource of benzene/alcohol extractives from Artocarpus lingnanensis Leavies were analyzed by GC/MS. Relative content of...
The behavior of formaldehyde release from plywood was similar to the creep behavior of material and the liquid. So the behavior of the formaldehyde emission from plywood was modeled by the rheological theory. And the Maxwell model, Delvin model and Burger model were used to fit the creep behavior which the formaldehyde released from plywood. The results show that the derived creeping model is fit...
The chemical composition of fresh Cinnamomum camphora were separated and analyzed by GC/MS. It was determined that 17 relative content by area normalization. 17 compounds of the extractives were identified. The main and abundant constituents were Eucalyptol, 3-Cyclohexen-1-ol,bicyclo[3.1.0]hexane, 4-methylene, beta.-Pinene, 3-Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl), 1,3-Cyclohexadiene, 1-methyl-4-(1-methylethyl),...
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...
