Abstract: The composition of the essential oils obtained by hydrodistillation from the aerial parts of Salvia pinnata L. (Labiatae), collected during flowering and fruiting periods, were analyzed by GC and GC-MS. 37 compounds were identified representing 96.1 % of the essential oil obtained from the plant material collected during flowering period. 30 compounds were detected constituting 94.7 % of the essential oil of the plant material collected in fruiting period. The main components of the essential oils were characterized as bornyl acetate, camphor, camphene, bornyl formate, a -pinene and borneol. The oils were screened for antimicrobial activity by the micro-dilution assay against standard bacteria (Escherichia coli, Salmonella enterica, Staphylococcus aureus, Enterococcus faecalis) and yeast (Candida albicans and Candida parapsilosis). Both of the oils showed antimicrobial activity against the tested organisms.
