Chemical Composition of Essential Oils Extracted from Aleppo Pine (Pinus halepensis Miller) and Their Termiticidal andFungicidal Effects

摘要

The essential oils used in this study were isolated from Aleppo pine. The chemical composition was investigated using GC-MS. Thirty-seven and thirty-two compounds, representing 91.01and 99.82% from leaves and cones respectively, of the total collective essential oils were identified. Essential oils were dominated by hydrocarbon compounds especially monoterpenes. The major compounds from oils stations were: caryophyllene (40.78%), a-pinene (10.30%); H-cycloprop [e]azulene, decahydro-l,l,7-trimethyl-4-methylene-,[laR-(laa,4aa,7a,7aa,7ba)] (9.53) and 3-carene (7.58%) from needles and caryophyllene (38.26%); 3-carene (31.78%); bicyclo [3.1.0] hexane, 4-methylene-l-(1-methylethyl) (11.74%); 1,4-cyclohexadiene and 1- methyl-4- (l-methylethyl)-(3.01%) fromcones. The essential oils revealed an interesting termiticidal and fungicide activity effects against dry-wood termites Kalotermes flavicollis and damping-off fungi {Fusarium solani and Rhizoctonia solani). Results of the present study indicate that theneedles and cones of Pinus halepensis are promising potential sources of green pesticides and safe environmental applications for human, animal and plant health.
