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 ${mu}m$ PDMS, 65 ${mu}m$ PDMS/DVB, 65 ${mu}m$ SF-PDMS/DVB, 85 ${mu}m$ PA, 75 ${mu}m$ CAR/PDMS, 65 ${mu}m$ CW/DVB and 50/30 ${mu}m$ 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 $alpha$-pinene ($1.7~21.7;{mu}g/g$), $eta$-myrcene ($2.0~20.1;{mu}g/g$), $eta$-phel-landrene ($4.6~22.8;{mu}g/g$), $eta$-caryophyllene ($6.7~26.0;{mu}g/g$) germacrene D ($1.1~11.9;{mu}g/g$). 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.
