TY - JOUR T1 - Antimicrobial activities and usage in folkloric medicine of some Lamiaceae species growing in Mugla, Turkey JF - EurAsian Journal of BioSciences Y1 - 2007 A1 - Nurdan Sarac A1 - Aysel Ugur SP - 28–37 AB - In this study; 23 selected plant species belonging to the Lamiaceae family, used in traditional treatments, were collected from different localities of Mugla, dried and extracted with ethanol using the soxhlet extraction apparatus. The antimicrobial activities of the plant extracts on the various test microorganisms, including multiple antibiotic resistant bacteria, were investigated. Antimicrobial activities of the extracts were determined by the disc diffusion method. Test microorganisms were; 7 Gram positive, 7 Gram negative bacteria and Candida albicans. Also different standart antibiotic discs were used for comparison for the inhibition zones. The antimicrobial activities of the ethanolic extracts of Salvia verbenaca, Teucrium chamaedrys ssp. lydium, Teucrium divaricatum ssp. villosum, Teucrium polium, Stachys annua ssp. annua var. annua, Sideritis albiflora, Sideritis leptoclada and Prunella vulgaris demonstrated the inhibition effects against Gram positive bacteria including multiple antibiotic resistant Staphylococcus strains. The ethanolic extract of S. leptoclada was the most effective extract. On the contrary, all of the ethanolic extracts were not effective on Gram negative bacteria and C. albicans. The ethanolic extracts of the plants, which inhibited the bacteria, mostly inhibited the growth of Staphylococcus aureus ATCC 25923, MU 38, MU 44 and Staphylococcus epidermidis. Even the inhibition zone of S. leptoclada on S. aureus ATCC 25923 was greater than the inhibition zone of oxacillin on the same bacteria. VL - 4 UR - www.ejobios.com/content/1/4/28-34 ER -
