Sažetak
In the present study, the phytohemical composition and the antibacterial activity of the essential oils obtained from the aerial parts of the two Lamiaceae species, winter savory (Satureja montana L.) and wild savory (Satureja cuneifolia Ten.) were evaluated. The gas chromatography-mass spectrometry (GC-MS) analysis of the isolated oils resulted in the identification of twenty compounds in the oil of S. montana representing 97% of the total oil and 25 compounds of S. cuneifolia, representing 80% of the total oil. Carvacrol was the major constituent of the S. montana oil (45.7%). Other important compounds were monoterpenic hydrocarbons p-cymene, γ -terpinene and oxygenated compounds carvacrol methyl ether, borneol and thymol. On the contrary, the oil of S. cuneifolia contained poor percentage of carvacrol and thymol. The major constituents of the wild savory oil were sesquiterpenes β -cubebene (8.7%), spathulenol, β -caryophyllene, followed monoterpenic hydrocarbons limonene and α -pinene. The screening of the antimicrobial activities of essential oils were individually evalated against nine microorganisms, using a disc diffusion metod. The oil of S. montana exhibited greater antimicrobial activity than the oil of wild savory. Maximum activity of winter savory oil was observed against Escherichia coli, methicillin-resistant Staphylococcus aureus and against yeast (Candida albicans). The essential oil of S. cuneifolia was also found to inhibit the growth of medically important pathogens such as S. aureus and E. coli. The fungicidal activity in both oils against C. albicans and Saccharomyces cerevisiae was also observed.
