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,...
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...
Gigantochloa ligulata is both a wide use as biomatrals and an antiquity as medicine. It contains many kinds of organosufide compounds. Therefore, Py-GC/MS was used to analyse and evaluate the application potential of Gigantochloa ligulata for biomedicine. The results indicated that the main components of the Gigantochloa ligulata by Py-GC/MS were carbon dioxide (19.67%), acetic acid (16.08%), acetone...
As a ideal raw material in bioenergy, extractives of Cunninghamia lanceolata wood are severely wasted. Therefore, the chemical components from Cunninghamia lanceolata wood were extracted with benzene /ethanol and identified by Py- GC/MS after concentration. Relative content of each component was determined by area normalization. 83 compounds of the extractives were identified. The main constituents...
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...
The extractives from masson pine (Pinus massoniana L.) wood would not only consume bleaching agent and other additives, but also aggravate environmental pollution. Therefore, Py-GC/MS was used to analyze the high-grade resource recovery of acetone extractives of masson pine wood. Relative content of each component was determined by area normalization. The main and abundant constituents of 590degC...
