Özet

In present studies, the chemical composition and antimicrobial activity of the essential oil of Evernia prunastri (L.) Ach. and Evernia divaricata (L.) Ach have been analyzed. The essential oils obtained by hydrodistillation from of E. prunastri and E. divaricata, were identified by GC and GC-MS. Main component was monoterpenes, such as tricyclene (0.5 and 2.2 %), alpha-pinene (6.6 and 7.2 %), camphene (3.0 and 3.1 %), beta-pinene (6.3 and 8.0 %), alpha-phellandrene (3.3 and 4.1 %), limonene (1.6 and 6.3 %), gamma-terpinene (0.5 and 1.9 %), terpinolene ( and 3.1 %) and p-cymene (1.5 and 1.8 %), respectively. The inhibitory effects of the essential oils of E. prunastri and E. divaricata were tested against seven bacterial species using the disc-diffusion method and E. divaricata oil exhibited the antimicrobial and antifungal activity, whereas, E. prunastri showed only antifungal activity.
