چکیده
|
The extraction yield of the essential oil (eo) extracted by hydrodistillation from the cones of tunisian cupressus sempervirens l. was of 0.518%. the chemical composition was analyzed by gc-ms. results showed that this essential oil was mainly composed of monoterpene hydrocarbons (65%) with -pinene as the major constituent (47.51%). its antioxidant activity was ascertained by evaluating the total antioxidant capacity and also by evaluating its inhibitory effect against dpph and abts radicals. in addition,it showed a strong antioxidant power against the dpph (ic= 151 μg/ml) and abts (ic= 176.454 μg/ml) radicals scavenging. moreover,its antibacterial activity was tested against different species of pathogenic bacteria (three gram-positive and eight gram-negative bacteria). the bacterial strains susceptible to the evaluated oil were bacillus subtilis,escherichia coli,klebsiella oxytoca,morganella morganii,shigella,and vibrio cholerae. © 2015 aicha ben nouri et al.
