Cunninghamia lanceolata is medicinal plant in South China, and its wood extractives are greatly applied in the therapy and protection of human diseases. Therefore, the nano biomedical components of the acetic ether extractives of Cunninghamia lanceolata biology were studied by Py-GC/MS to find new specific drug. 93 compounds of the extractives were identified. The main constituents were cedrol (18...
Wood extractives for bioenergy with high additional value is looked upon as a strategy task. In this paper, the chemical components in the benzene/ethanol extractives of Eucalyptus urophylla wood were isolated and identified by Py-GC/MS so as to increase economic benefits. In this paper, the chemical components in the acetic ether extractives of Eucalyptus urophylla wood were isolated and identified...
As a waste in pulp, the acetone extractives of Eucalyptus urograndis wood severely polluted the water and wasted a lot of bleaching agents. Therefore, Py-GC/MS was used to analyze high-grade bioenergy utilization of acetone extractives of Eucalyptus urograndis wood. The relative content of each component was determined by peak area normalization. 33 compounds in the extractives were identified. The...
Bambusa blumeana is the one of the most impotent bamboo species in South China. In order to exploit the high- grade resource utilization as bioenergy, determination of chemical components in Bambusa blumeana was made by using Py-GC/MS. Results indicated that the main components of Bambusa blumeana by Py-GC/MS analysis were carbon dioxide (30.99%), acetic acid (13.67%), tuaminoheptane (9.81%), diazene,...
The extractives from masson pine (Pinus massoniana L.) bark has been used in medicine successfully. Therefore, Py-GC/MS was used to analyze the high-grade resource recovery of benzene/ethanol extractives of masson pine wood. Relative content of each component was determined by area normalization. The main and abundant constituents of 590deg pyrolysis product of masson pine wood werel-phenanthrene...
Phenol-formaldehyde resin is used as the most adhesive to produce waterproof plant-based composite. However, this product contains phenol and formaldehyde which can be easily released to pollute air. Based on the single-factor method, the effect of nano TiO2 on situation of cure and pyrolytic reaction of PF resin was studied by FT-IR and Py-GC/MS. The result of FT-IR spectrograms showed that the absorbencies...
