Abstract

Essential oil of Chamaecyparis obtusa showed antimicrobial on relatively broad spectrum of bacterial and fungal species. Staphylococcus epidermidis was highly sensitive to the essential oil but Streptococcus aureus and Streptococcus mutans were not. Vibro parahemolyticus, Pseudomoas aeruginosa and Pseudomoas putida showed sensitivity at the concentration higher that 400 ppm, Thegrowth of a pathogenic yeast Candida albicans was inhibited by the essential oil above 200ppm. The radialgrowth of several filamentous fungi was also inhibited The antifungal activity of the essential oil was effective on two plant pathogens Fusarium oxysporum and Altenaria mali. These results sug-gest that essential oil of Chamaecyparis obtusa has an antimicrobial activity by inhibiting bacterial and fungal species.

편백의 정유성분을 추출하여 수종의 병원성세균과 진균을 대상으로 항세균 및 항진균효과를 실험하여 다음과 같은 결과를 얻었다. 편백정유는 그람 양성균인 S epidermidis, 그람 음성균인 V parahemolyticus와 P. aeruginosa에 대해서는 200 ppm부터 항세균효과를 나타냈고, P putida에 대해서는 400ppm 부터 항세균효과를 나타냈다. 항세균효과가 나타난 균주들은 편백정유의 농도가 증가할수록 효과가 높게 나타났으며 통계적으로 유의성이 관찰되었다(p<0.05) 또한 편백정유는 효모형 곰팡이인 C, albicans에 대하여 200 ppm부터 항진균효과를 나타냈으며, 사상형 곰팡이인 A, mali와 A, nidulans에 대해서는 400 ppm부터 F. oxyporum 에 대해서 100 ppm 부터 항진균효과를 보였고 편백정유의 농도가 증가할수록 균주의 성장억제대가 증가되었다. 따라서 편백을 항균제나 방부제로 사용할수 있는 가능성을 확인하였다.
