Determination of Biomedicine Resource of Benzene/Ethanol Extractives of Masson Pine(Pinus Massoniana L.) Wood by Py-GC/MS

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 carboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1- methylethyl)- 1(31.66%), oleic Acid (20.63%), pimaric acid (10.24%), 9,12-octadecadienoic acid (Z,Z)- (5.99%), (1-chlorovinyl)triethylsilane (1.92%), 9,17-octadecadienal, (Z)- (1.82%), 9,10-anthracenedione, 1-amino-2-methyl-(1.70%), oxacyclohexadecan-2-one (1.55%), oleic acid (1.46%), benzaldehyde, 3-[4-(1,1-dimethylethyl)phenoxy]- (1.40%), hexadecanoic acid(4.40%), cedrol(1.23%), 9-octadecenal, (Z)- (1.22%), octadecanoic acid (0.97%), ergosta-4,6,22-trien-3.beta.- ol(0.83%), .gamma.-Sitosterol(0.57%), etc. The analytic result suggested that the benzene/ethanol extractives of masson pine wood can be used as materials of biomedicine, skin care and cosmetic, flavor and bioenergy.
