Antimikrobni učinak eteričnog ulja smreke - Picea abies (L.) Karsten

Activity of the essential oil of Picea abies (L.) Karsten against 25 species of bacteria and fungi was determined by agar diffusion and broth dilution methods. The essential oil was isolated by hydrodistillation. Bornylacetate, alpha- and beta-pinene and phellandrene were characterised as the main components of the oil by thin layer chromatography. The essential oil inhibited the growth of the most tested bacteria in wide concentration range from 0.05 vol% to 12.5 vol%, while the yeasts were sensitive to 0.05-0.8 vol% concentrations. The highest toxicity of the investigated oil was established against the mycelial growth of tested dermatophytes (MIC: 0.01-0.1 vol%).
