The interest of natural chemicals has been increased because of inflection of endocrine disruptor and fatal health danger originated from artificial chemical compounds. The essential oil is one of the representative natural chemicals which can be collected from the most plants and can be applied to high value‐added merchandise such as the antiseptics, anti‐oxidants and deodorants. In this study, essential oil was testified to remove odor such as NH3. In case of the essential oil of a pine leaf, removal efficiency of NH3 was about 100%. The NH3 removal efficiency of the mixed solution (mixture of essential oil and ethanol) was slightly lower than that of pure essential oil and this leads to the conclusion that use of mixture is more economical and effective to control the odor.

본 연구는 방향성 약용작물인 삼백초, 구릿대, 천궁의 향기 성분 조성과 식물정유 함량을 조사하여 향료업과 관련된 다양한 식품첨가물 또는 향원 가능성을 알아보기 위하여 몇가지 실험한 결과를 요약하면 아래와 같다. 1. 삼백초의 향기성분은 22종으로 1,6-octadien-3-ol, 1, 3-benzodioxole, myristicin, α-cadinol, patchouene였고 조성은 alcohol류 6종, ester류 1종, ether류 2종, hydrocarbon류 11종, ketone류 1종, fatty acid류 1종이었다. 2. 구릿대의 향기성분은 14종으로 주요 성분은 3-carene, β-caryophyllene, β-cubebene, butylated hydroxytoluene, caryophyllene oxide, piperonal이었고 조성은 alcohol류 1종, ester류 1종, ether류 1종, hydrocarbon류 10종, aldehyde류 1종이었다. 3. 천궁의 향기성분은 16종으로 주요성분은 aristolene, benzocycloheptene, ylangene, valencene, β-cedrene, satene, and menthofuran이었고 조성은 alcohol류 2종, ether류 1종, hydrocarbon류 12종. furan류 1종이었다. 4. 삼백초, 구릿대 및 천궁 잎의 식물정유 함량은 각각 0.987%, 0.452%, 0.439%로 삼백초가 가장 높은 함량을 보였다.
