精油具有潜在的生物效应，即抗生素、抗癌和压力期间的镇静作用。在本研究中，我们研究了从针叶树种赤松、红松和扁柏中提取的精油的抗菌和抗真菌作用，因为它们的生物活性尚未阐明。使用气相色谱对精油进行定量，并通过气相色谱-质谱分析进行鉴定。同时，使用从针叶树针中蒸馏的精油进行抗菌和抗真菌测定。各精油的主要成分及含量为：赤松中β-侧柏烯19.33%；红松中 10.49% α-蒎烯； C. obtusa 中含有 10.88% 的乙酸冰片酯。 P. densiflora 和 C. obtusa 的精油具有抗菌作用，而 P. koraiensis 和 C. obtusa 的精油则具有抗真菌作用。这些结果表明，这三种针叶树的精油具有温和的抗菌特性，可以抑制革兰氏阳性和革兰氏阴性细菌和真菌的生长。
Essential oils have potential biological effects, i.e., antibiotic, anticarcinogenic, and sedative effects during stress. In the present study, we investigated the antibacterial and antiffingal effects of essential oils extracted from the coniferous species Pinus densiflora, Pinus koraiensis, and Chamaecyparis obtusa, because their biological activities have not been yet elucidated. The essential oils were quantified using gas chromatography and identified in gas chromatography-mass spectrometric analysis. Simultaneously, antibacterial and antifungal assays were performed using the essential oils distilled from the needles of coniferous trees. The major components and the percentage of each essential oil were: 19.33% beta-thujene in P. densiflora; 10.49% alpha-pinene in P. koraiensis; 10.88% bornyl acetate in C. obtusa. The essential oils from P. densiflora and C. obtusa have antibacterial effects, whereas essential oils from P koraiensis and C. obtusa have antifungal effects. These results indicate that the essential oils from the three coniferous trees, which have mild antimicrobial properties, can inhibit the growth of gram-positive and gram-negative bacteria and fungi.
