The investigation of chemical composition and antimicrobial activity of the essential oil of Galatella linosyris was presented. Chemical analysis (GC/MS, NMR) showed that sabinene (40%), β-pinene (35.5%), α-pinene (4.5%), limonene (4%), γ-muurolene (4%), and E-Caryophyllene (3.3%) were dominant components in this oil. The microdilution assays was used to evaluate minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC, MFC). G. linosyris essential oil exhibited better antifungal than antibacterial activity.
