Determination of Bioenergy Components in Benzene/Ethanol Extractives of Cunninghamia Lanceolata Wood by Py-GC/MS

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 were anthracene, 9-dodecyltetradecahydro- (11.78%), cedrol (9.12%), 1H- cycloprop[e]azulene, 1a,2,3,4,4a,5,6,7b-octahydro-1,1,4,7-tetramethyl- (6.22%), 1H-3a,7-methanoazulene, 2,3,4,7,8,8a-hexahydro-3,6,8,8- tetramethyl- (5.46%), 1-naphthalenepropanol, .alpha.-ethenyldecahydro- .alpha.,5,5,8a-tetramethyl-2-methylene- (4.09%), 1-naphthalenepropanol, .alpha.-ethenyldecahydro-5-(hydroxymethyl)-.alpha.,5,8a-trimethyl-2- methylene- (3.64%), phenol, 2-methoxy-4-propyl- (3.34%), .alpha.- bisabolol (3.27%), germacrene B (3.19%), 2(1H)-pyridinone, 1,4,6- trimethyl- (3.14%), hexadecanoic acid (3.09%), etc. The benzene /ethanol extractives could be used as bioenergy and biomedicine.
