Composition and antimicrobial activity of the essential oil from Galatella linosyris (L.) Rchb. f. (Asteraceae)

Abstract

An investigation of the chemical composition and antimicrobial activity of the essential oil of Galatella linosyris is presented. The chemical analysis (GC/MS, NMR) showed that sabinene (40 %), beta-pinene (35.5 %), alpha-pinene (4.5 %), limonene (4 %), gamma-muurolene (4 %), and (E)-caryophyllene (3.3 %) were dominant components in this oil. Microdilution assays were used to evaluate the minimum inhibitory concentration (MIC) and the minimum bactericidal/fungicidal concentrations (MBC/MFC). G. linosyris essential oil exhibited better antibacterial activity against some of the tested bacteria than antifungal activity.

U ovom radu je prikazano ispitivanje hemijskog sastava i antimikrobne aktivnosti etarskog ulja biljne vrste Galatella linosyris. Hemijskom analizom (GC-MS i NMR) je utvrđeno da su glavni sastojci ovog etarskog ulja sabinen (40 %), β-pinen (35,5 %) , α-pinen (4,5 %), limonen (4 %), γ-muurolen (4 %) i (E)-kariofilen (3,3 %). Za procenu minimalne inhibitorne koncentracije (MIC) i minimalne baktericidne/fungicidne koncentracije (MBC/ /MFC) korišćeni su testovi mikrorazblaženja. Etarsko ulje G. linosyris je pokazalo bolju antibakterijsku nego antifungalnu aktivnost.
