Abstract
- Background/Aim. Plant essential oils (EOs) can have a significant antibacterial effect especially through additive or synergistic action as antibiotic adjuvants. We investi-gated the composition and activity of EOs of two species of genus Salvia (S) from Greece with the aim to deter-mine their antimicrobial activity as well as the activity in combination with selected antibiotics. Methods. The aerial parts of wild-growing S. fruticosa and S. ringens were subjected to a steam distillation and the obtained EOs were analyzed by gas chromatography and gas chroma-tography/mass spectrometry. The broth-microdilution method was used in order to determine the minimum in-hibitory concentrations (MICs) of EOs on seven strains of bacteria and one yeast. Antimicrobial activity of the combination of EO and antibiotics was investigated by checkerboard method and estimated by calculating frac-tional inhibitory concentration (FIC) of each component and fractional inhibitory concentration index (FICI). Re-sults. Dominant component of S. fruticosa EO was trans-thujone (54.2%) and for S. ringens EO it was α-pinene (28.1%). The MICs of EOs of both species were in the range from 200 μg/mL to > 500 μg/mL. The strongest antimicrobial effect was achieved against Bacillus subtilis and Candida albicans. According to FICI values, EO of S. fruticosa had additive effect with ciprofloxacin against most of bacterial strains but not with amikacin. Conclu-sion. The essential oils of S. ringens and S. fruticosa showed modest antimicrobial activity. However, the es-sential oil of S. fruticosa showed a promising additive ef-fect in combination with ciprofloxacin. Uvod/Cilj. Etarska ulja različitih biljaka mogu imati značajna antibakterijska svojstva, posebno kao adjuvanti antibiotika sa kojima ostvaruju aditivno ili sinergistično dejstvo. Ispitivali smo sastav i aktivnost etarskih ulja dve vrste roda Salvia (S) iz Grčke sa ciljem da odredimo njihovu antimkrobnu aktivnost, kao i dejstvo u kombi-naciji sa odabranim antibioticima. Metode. Nadzemni delovi samoniklih S. fruticosa i S. ringens su destilovani vodenom parom i dobijena etarska ulja su analizirana gasnom hromatografijom i gasnom hromatografijom sa masenom spektrometrijom. Radi određivanja minimalnih inhibitornih koncentracija (MICs) etarskog ulja na sedam sojeva bakterija i na jednoj patogenoj gljivici korišćena je mikrodiluciona metoda. Antimikrobna aktivnost kombi-nacije etarskog ulja i antibiotika ispitana je checkerboard metodom i procenjena je na osnovu frakcione inhibi-torne koncentracije (FIC) svake komponente i indeksa frakcione inhibitorne koncentracije (FICI). Resultati. Dominantna komponenta etarskog ulja S. fruticosa je bio trans-tujon (54,2%), a etarskog ulja S. ringens α-pinen (28,1%). MICs etarskog ulja obe vrste su bile u opsegu od 200 μg/mL do > 500 μg/mL. Najsnažnija anti-mikrobna aktivnost ostvarena je protiv Bacillus subtilis i Candida albicans. Na osnovu FICI vrednosti, etarsko ulje S. fruticosa je sa ciprofloksacinom, ali ne i sa amikacinom imalo aditivni efekat protiv većine bakterijskih sojeva. Zaključak. Etarska ulja S. ringens i S. fruticosa su pokazala skromnu antimikrobnu aktivnost, ali je etarsko ulje S. fru-ticosa u kombinaciji sa ciprofloksacinom ispoljilo značajan aditivni efekat.
