Essential Oil Components of Leaves and Resins from Pinus densiflora and Pinus koraiensis

소나무와 잣나무의 잎과 수지에 함유된 정유 성분

The essential oils of leaves and resins from P. densiflora and P. koraiensis were analyzed to identify their components. After each retention times of 45 known terpenoids were dertermined with a fixed analytical condition by GC the essential oil compounds of leaves and resins were identified by comparing their retention times with the retention times of known standards. To confirm these results the essential oil components of leaves from P. koraiensis were analized by 2 different GC/MS. According to these results, 36 terpenoids in essential oils of leaves from P. densiflora and P. koraiensis were identified and 15 terpenoids and 22 terpenoids were identified from P. koraiensis resin and P. densiflora resin, respectively. The major components which are more than 2% of total amaunt of volatile components were as follows: 1. The major terpenoids of leaves from red pine. ${\alpha}$-pinene, camphene, ${\beta}$-pinene, D-limonene, ${\beta}$-phellandrene, myrcene, terpinolene, ${\alpha}$-terpineol. 2. The major terpenoids of leaves from korean pine. ${\alpha}$-pinene, camphene, myrcene, D-limonene, 3-carene, terpinolene, bornyl acetate, ${\beta}$-caryophyllene, ${\alpha}$-terpineol, borneol, ${\delta}$-cardinene. 3. The major terpenoids of resin from red pine. ${\alpha}$-pinene, ${\beta}$-pinene, myrcene, ${\beta}$-phellandrene, linalool, linalyl acetate. 4. The major terpenoids of resin from korean pine. ${\alpha}$-pinene, ${\beta}$-pinene, D-limonene, ${\beta}$-caryophyllene, phytol.
