Study on Determination and Composition of Volatile Organic Compounds of Larix gmelini Particles
The static head space solid-phase micro-extraction (HS-SPME) technique was applied to extract the volatile organic compounds of Larix gmelini particles,and the extracting condition was optimized, that is, 40 minute extracting time at 80 ℃, then 30 minute absorption, 4 minute desorption. The volatile organic compounds (VOCs) of Larix gmelini particles were analyzed by head space solid-phase micro-extraction gas chromatography-mass spectroscopy (HS-SPME-GC-MS) under the optimal testing condition. The results show that 9 kinds of compounds were analyzed and identified with HS-SPME-GCMS. And the main component was alpha-pinene (0.334 of mass fraction), then beta-phellandrene (0.130 of mass fraction),hexanal (0.113 of mass fraction), 3-carene (0.094 of mass fraction), and 2, 6-bis (1, 1-dimethylethyl)-4-(1-methylpropyl)-phenol (0.031 of mass fraction). The further study of VOCs emission of Larix gmelini panels can be supported by the optimized condition and raw materials component analysis.
