Abstract
Volatile compounds from three parts of needles, sprouts and twigs in Pinus densiflora were extracted by solid phase microextraction (SPME) and dynamic headspace analysis (DHA). separated by gas chromatography, and identified by using mass selective detecter and Kovat's retention index. The amounts of monoterpenes isolated by SPME and DHA were 66.7% and 14.3% in needles, 90.6% and 0.7% in sprouts, and 90.6% and 1.2% in twings, respectively. The amounts of sesquiterpenes detected only by SPME were 25.8% in needles, 4.4% in twings and 1.5% in sprouts. And the amounts of oxygenated terpenes isolated by SPME and DHA were 4.7% and 79.0% in sprouts, 3.7% and 70.4% in twigs, and 1.0% and 50.7% in needles, respectively. The kinds of volatile compounds isolated by SPME were similar to those by solvent extraction, but the number of compounds identified to hate a boiling point below 5$0^{\circ}C$ by UHA was larger than that of SPME.
