title: The in vitro antimicrobial activities of the essential oils of some Lamiaceae species from Turkey.
abstract: In this study, antimicrobial activities of the essential oils obtained by using the hydrodistillation method from some lamiaceous plants--Mentha longifolia (L.) Hudson ssp. longifolia, M. longifolia (L.) Hudson ssp. typhoides (Briq.) Harley var. typhoides, Mentha pulegium L., Salvia fruticosa Miller, Salvia tomentosa Miller, Calamintha nepeta (L.) Savi ssp. glandulosa (Req.) P.W. Ball, Nepeta cadmea Boiss., Lavandula stoechas L. ssp. stoechas, and Ziziphora tenuior L.--were determined by using the disc diffusion method. The plants used in this study were collected from different localities of Muğla Province, Turkey. All the essential oils isolated from the plants were very effective against Gram-positive and Gram-negative bacteria, which included multiple-antibiotic resistant strains, except Pseudomonas aeruginosa ATCC 27853 and Pseudomonas fluorescens MU 87. The essential oils of the plant species, except S. tomentosa and S. fruticosa, were very effective against Candida albicans. The antimicrobial activities varied depending on the species, subspecies, or variety. In fact, essential oils of some plants belonging to the same taxa but collected from different localities showed different levels of antimicrobial activities.
