Twenty seven compounds representing 92.095% of T. persicus and 99.77% of Thymus eriocalyx essential oils were identified. The major constituents of T. persicus were thymol (10.71%), carvacrol (25.71%), γ-terpinene (5.63%), α-pinene (1.14%), β-pinene (1.02%), limonene (11.65%) trans-sabinene hydrate (7.78%) and l-borneol (4.07%) and the major compounds of T. eriocalyx. were 1, 8-cinole (3.07%), L-linalool (1.01%), thymol (66.34%), caryophyllene oxide (2.96%) and carvacrol (7.5%). The oils also were examined for antibacterial activities against 6 standard bacteria by the broth microdilution and disc diffusion methods. They exhibited significant antibacterial activities against Staphylococcus aureus (MIC =1 : 235, MBC =1:20), Escherichia coli (MIC = 1:320, MBC =1:80) and Pseudomonas aeroginosa (MIC = MBC = 1: 1280). The results were compared with control antibiotics.]]>Adams, R.P.,1995Pages: 456Pages: 456Arras, G. and G.E.
