Molecular Characteristics Analysis of Wood Extractives from Pinus Massoniana Trees

摘要

Pinus massoniana is a fast growing tree widely grown in China that is, unfortunately, difficult to process and develop due to the extractive substances. The molecular characteristics of the wood extractives from Pinus massoniana were removed by a method of petroleum ether/Benzene extraction and analyzed by gas chromatography-mass spectrometry (GC-MS) in order to provide scientific guidance for improving the processing and utilization of this plant. Twenty-eight chemical components were discovered, including: 1,2-Benzenedicarboxylic acid, butyl octyl ester (62.69%), 1,5-Hexadien-3-yne (6.00%), Squalene (3.31 %), 9,12-Octadecadienoic acid (Z,Z)- (1.29%), Heptadecane (1.14%) and Eicosane (1.01 %). The analysis of the GC-MS results show that the main retention time of the wood extractives is 20-30 minutes with a total content percentage of 80.18%, and the richest components are esters, which compose 80.01%.
