Abstract

The chemical compositions and antibacterial and antifungal activities of essential oils extracted from Abies holophylla and A. koreana were investigated. GC-MS analysis revealed that 38 compounds comprised 95.88% of the A. holophylla essential oil, with the main components being bicyclo[2.2.1]heptan-2-ol (28.05%), delta3-carene (13.85%), alpha-pinene (11.68%), camphene (10.41%), dl-limonene (7.61%), beta-myrcene (7.11%), trans-caryophyllene (5.36%), and alpha- bisabolol (3.67%). In the essential oil from A. koreana, 36 compounds comprised 98.67% of the oil, and the main compounds were bornyl ester (41.79%), camphene (15.31%), alpha-pinene (11.19%), dl-limonene (8.58%), fenchyl acetate (5.55%), and alpha-terpinene (2.29%). Both essential oils showed great potential of antibacterial activity against several bacteria tested, in the range of 2.2-8.8 mug per disc by the agar disc diffusion method, and minimal inhibitory concentration (MIC) values of 5.5-21.8 mg/ml by the microdilution method. Both oils showed very effective antifungal activities toward all pathogenic strains tested, including Candida glabrata, with MIC values in the range of 0.5-2.2 mg/ml. As a whole, A.koreanaoil showed better antibacterial and antifungal properties than A.holophylla oil.
