Abstract

The concentration of terpene (18 species) was measured from spring to fall in ambient air and essential oil at three different forests located in Jeollanamdo province. Sampling was conducted at 4-hour-interval a day of each season. In the ambient air, ${\alpha}$-pinene, ${\beta}$-pinene and 2-carene were the most abundant compounds throughout the sampling periods and areas. The highest three-season average concentration of total terpene was 2,597 pptv at Jeamsan(Mt.) in Boseong which was predominantly populated by Pinaceae. The seasonal averages were observed to peak during spring with their max at Palyeongsan(Mt.) in Goheung and Jeamsan(Mt.) in Boseong, and during fall at Woodland in Jangheung. Most of terpenes had diurnal variations with higher concentrations during the daytime, and lower during the nighttime. However in essential oil, the highest annual average concentration of total terpene was $798{\mu}g/dry-g$ at Goheung which was predominantly populated by Chamaecyparis obtusa. Also, the component proportion ratio showed different distribution between ambient air and essential oil. From the results of this study, we suggest that Chamaecyparis obtusa species is more useful, and younger tree is more economical than older one, and spring is the best season for lumbering in order to use essential oil.

산림공기 중 약리효과를 주는 것으로 알려진 모노테르펜류의 분포양태 파악을 위해 고흥 팔영산, 보성 제암산, 장흥 우드랜드 숲속 공기와 그 주변에 우점하고 있는 나무의 정유에서 ${\alpha}$-pinene, camphene, ${\beta}$-pinene, 2-carene, myrcene, ${\alpha}$-phellandrene, ${\alpha}$-terpinene, d-limonene, eucaliptol, cymene, terpinolene, linalool, camphor, menthol, borneol, thymol, asarone, coumarine 농도분포를 비교하였다. 숲속 공기는 3 계절(봄, 여름, 가을), 정유는 봄, 여름기간 수행하였다. 공기 중에는 4 시간 평균농도 기준으로 ${\alpha}$-pinene, ${\beta}$-pinene과 2-carene이 각각 높은 농도로 나타났다. 측정된 3계절 평균 농도는 소나무가 우점하고 있는 보성 제암산에서 2,597 pptv로 가장 높았다. 계절별로는 고흥 팔영산과 보성 제암산은 봄, 장흥 우드랜드는 가을에 최고치를 보였다. 정유 중 테르펜은 편백나무가 우점하고 있는 고흥 팔영산이 가장 높았고, 장흥 우드랜드 >보성 제암산 순으로 숲속 공기와는 다른 분포형태를 보였다. 주요 성분도 달라 고흥 팔영산은 sabinene, myrcene, limonene이 높은 반면 장흥 우드랜드는 ${\alpha}$-terpinene, linalool, camphor가 보성 제암산은 cymene, camphor, borneol이 높게 나타났다. 정유 중 함량은 10~20령의 비교적 어린 편백나무가 높았고, 특히 봄철에 매우 높게 조사되어 정유를 활용하는 산림산업에 수종 및 채취시기 등을 시사해준다.
