The essential oils isolated from the fresh flowers, fresh leaves, and both fresh and air‐dried stems of Eremophila maculata (Scrophulariaceae) were characterized by GC‐FID and GC/MS analyses. Sabinene was the major component in most of the oils, followed by limonene, α ‐pinene, benzaldehyde, ( Z )‐ β ‐ocimene, and spathulenol. The leaf and flower essential oils showed antibacterial and antifungal activity against five Gram ‐positive and four Gram ‐negative bacterial strains, multi‐resistant clinical isolates from patients, i.e. , methicillin‐resistant Staphylococcus aureus (MRSA), as well as two yeasts. Minimum inhibitory concentrations ( MIC s) and minimum microbicidal concentrations ( MMC s) were between 0.25 and 4 mg/ml.
