    Abstract:
    The analysis of Skimmia laureola hydrodistillate by gas chromatography coupled with mass spectrometry revealed the presence of 20 constituents, representing 94.6% of the total oil. The major constituents of oil were linalyl acetate (33.0%), linalool (25.0%), limonene (8.1%), α-terpineol (5.9%) and geranyl acetate (5.9%). The monoterpene (93.4%) rich essential oil was evaluated for its antibacterial and antifungal activities against seven microorganisms by agar diffusion and microdilution methods. The oil showed appreciable antimicrobial effects against all Gram-positive bacteria tested, including methicillin-resistant Staphylococcus aureus and Staphylococcus epidermidis with MIC values 32 and 64 µg mL(-1), respectively. The oil also exhibited strong fungicidal activity against Aspergillus niger and Penicillium chrysogenum with MIC value in the range 32-16 µg mL(-1). The oil could be used in the formulation of antimicrobial agents.
