- Abstract
- Essential oil of Thuja occidental leaves was extracted by steam distillation method, and chemical compostiton of essential oil was analyzed by GC-MS. The essential oil was tested to antimicrobial activity against 28 test microorgani는 and antioxident assay through DPPH free radical scaveging test and insecticidal activity by mosquito insecticide assay. The major constituents in the essential oil of T. occidental were monoterpene as d-isothujone, α-thujone,camphor, L-fenchone, and bornyl acetate. The exxential oil have broad antimicrobial activity, which showed strong antimicrobial activity for Streptococcus pyogenes as bacteria, Alternaria alternata, Aspergillus niger, Aspergillus oryzae, Saccharomyces cerevisiae, and Streptococcus mutans as fungi. The essential oil also showed DPPH free radical scavenging ability at concentration of 36㎕/㎖. In spraying and fumigation tests, the essential oil had strong insecticidal activity against mosquito.
