 Abstract

The chemical composition of essential oil, isolated from Evernia prunastri and Ramalina farinacea by hydrodistillation, was analysed by GC and GC/MS. A total 32 compounds representing 93.64% of the oil were identified in E. prunastri. This oil is characterised by an n-octadecanol (54.06%), n-tetradecanol (8.27%), Heptadecane (4.70%), Eicosene-1 (3.82%), n-hexadecanol (2.32%), Tridecenol acetate (2.05%). Ramalina farinacea with 34 compounds, representing 76.04% of the total oil, is characterised by the Manool (14.21%), n-octadecanol (10.24%), Eicosene-1 (8.26%), n-tetradecanol (7.68%), Manool oxide-13-epi (5.40%), α-pinene (4.04%), Abietal (3.75%). To test the antibacterial activity of essential oil of these species, four bacteria are used in this study. The oils have shown little effect against gram-negative bacteria, and modest antibacterial activity against Gram positive bacteria.
