        서양측백나무의 잎으로부터 정유를 steam distillation법으로 추출하고, GC-MS로 정유 조성성분을 분석하였으며, 28종의 미생물종을 대상으로 항균활성을, DPPH법으로 항산화 활성을, 집모기에 대한 살충효과를 검정하였다. 서양측백나무 정유 주성분은 monoterpene류였으며, d-isothujone, l-fenchone, α-thujone, camphor, terpin-4-ol 순으로 나타났다. 정유의 박테리아에 대한 항균력은 박테리아 중 Streptococcus pyogenes에서, 그리고 효모 및 곰팡이 중 Candida albicans에서 가장 높게 나타났다. 특히 서양측백나무 정유는 그램 양성균의 박테리아에 대해 가장 장한 항균력을 보였다. 정유는 DPPH radical 소거능을 보유하고 있었으며, EC50 값은 36 μl/ml이었다. 집모기에 대한 살충 효과는 분무, 훈증, 자연증발 등 처리방법에 따라 다르게 나타났으며, 그 중 분무처리가 가장 효과적인 것으로 나타났다. 이상의 결과는 환경 친화적인 항균 및 살충소재로 이용될 수 있을 것이다.

        The number of natural products obtained from plants has now reached over 100,000 and new chemical compounds are being discovered ever year. Medicinal and Aromatic plants and their extracts have been used for centuries to relieve pain, aid healing, kill bacteria and insects are important as the antifungal and anti-herbivore agents with further compounds being involved in the symbiotic associations. Although their functions in plants have not been fully established, it is Known that some substances have growth regulatory properties while others are involved in pollination and seed dispersal. The complex nature of these chemicals are usually produced in various types of secretory structures which is an important character of a plant family and also influenced and controlled by genetic and ecological factors. Detailed anatomical description of these structures ave relevant to the market value of the plants, the verification of authenticity of a given species and for the detection of substitution or adulteration. Volatile oils are used for their therapeutic action for flavoring of lemon, in perfumery of rose or as starting materials for the synthesis of other compounds of turpentine. For therapeutic purposes they are administered as inhalations of eucalyptus oil, peppermint oil, as gargles and mouthwashes of thymol and transdermally many essential oils including those of lavender, etc. With these current trend for using volatile components in essential oil will be increasing in the future in Korea and in the world as well.

        This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were α-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.

        This experiment was carrie out to investigate the amount of essential of leaves and fruits of Magnolia sieboldii, Magnolia hypoleuca, Evodia danillii male and female, Phellodendron amurense male and female and Zanthoxylum schinifolium male and emale by Karlsrube set on August, August, September and October in 1994. Essential oil yield was highest in the fruits of Zanthoxylum schinifollium leaves on Augus the amount of essential oil of Magnolia sieboldii and Magnolia hypoleuca leaves was more than the one of Evodia danillii, Phellodendron amurense and Zanthoxylum schnifolium leaves. The amount of essential oil were not diferent between male and female leaves.

        형개의 잎, 줄기 및 화수의 정유함율 및 정유구성성분을 생육시기별로 비교 분석하여 조사한 결과를 요약하면 다음과 같다. 1. 형개의 정유함율은 잎이 줄기나 화수에 비하여 월등히 높았으며 영양성장기부터 개화 후반결관까지 생육이 진전됨에 따라 잎과 줄기의 정유함율은 증가하였다. 2. 정유성분의 구성은 잎과 화수의 경우는 d-menthone과 l-pulegone이 56~71%의 함유 비율을 나타내었으며, 줄기는 21~26%의 함유비율을 보이고 잎과 화수에 거의 나타나지 않는 두 물질이 확인 되었다. 3. 잎의 정유성분구성은 생육후기로 갈수록 d-menthone은 생육초기에 많았다가 후기에 증가하는 반면에 l-pulegone은 점차 감소하여 두가지 주정유성분의 함유비율이 서로 반대로 나타났다. 4. 형개의 정유 성분 평가를 위하여 주요 성분의 생약 약리학적인 검토가 필요하다.
