Abstract

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 α-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 IC50 = 151 µg-mL and ABTS IC50 = 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.
