Volatile Component of Pine Needles from Pinus densiflora S. using Solid Phase Microextraction-Ges Chromatography-Mass Spectrometry

The volatile components of Pinus densiflora needles were studied by gas chromatography-mass spectrometry(GC-MS), using seven kinds of solid phase microextraction (SPME) fibers, seven in SPME fibers: 100 PDMS, 65 PDMS/DVB, 65 SF-PDMS/DVB, 85 PA, 75 CAR/PDMS, 65 CW/DVB and 50/30 DVB/CAR/PDMS fibers. A total of 40 components were identified by using the seven different SPME fibers. The identified components were classified, according to their functionalities, as follows: 26 hydro-carbons, 7 alcohols, 4 carbonyl compounds, and 3 esters. The major volatile components of Pinus densiflora needles identified by these SPME fibers were -pinene (), -myrcene (), -phel-landrene (), -caryophyllene () germacrene D (). In the comparison of the seven SPME fibers, PDMS appeared to be the most suitable fiber for the analysis of hydrocarbon compounds and CAR/DPMS, PDMS/DVB, CW/VB and DVB/CAR/PDMS are shown to be optimal for analysis of the alcohols and carbonyl compounds.
