초록
Pinus densiflora(2엽송) 1년생을 채취하여 가지, 잎, 새순 부분으로 구분하고, 시료병에 넣어 밀봉한 뒤, solide phase microextraction(SPME)과 dynamic headspace analysis(DHA)를 이용하여 휘발성 성분을 분리, 동정하였다. SPME와 DHA의 결과를 terpenes의 구성 성분에 따라 monoterpenes과 sesquiterpenes, oxygenated terpenes으로 나누어 조성비를 살펴보면, monoterpenes의 조성은 잎의 경우 각각 66.7%와 14.3%, 새순은 90.6%와 0.7%, 가지에서는 90.6%와 1.2%로 나타났다. Sesquiterpenes의 함량은 SPME의 결과에서만, 잎이 25.8%, 가지 4.4%, 새순 1.5%로 나타났다. 산소를 함유하고 있는 terpenes의 함량은 새순 부위가 4.7%, 79.0%로 나타났으며, 가지 부위는 3.7%와 70.4%, 잎에서 1.0%와 50.7%
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 detector 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 have a boiling point below 50oC by DHA was larger than that of SPME.
