Abstract

In this study performed on six endemic plant species, antimicrobial activity was observed in Campanula lyrata subsp.lyrata and Abies nordmanniana subsp. bornmuellerianaplants. The minimum inhibitory concentration of C. lyrata subsp. lyrata (leaf and flower) extract was found to be ≥ 29 mg/ml for Baccillus subtilis and ≥ 14.5 mg/ml forStaphylococcus aureus, and the minimum inhibitory concentration (MIC) of Abies nordmanniana subsp. bornmuelleriana (leaf) extract was found to be > 314 mg/ml forB. subtilis and when minimum bacteriocidal concentration (MBC) results were evaluated, it was observed that the plant extracts had bacteriocidal effects. No antimicrobial activity was observed in the other plant extracts, namely, Onosma bornmuelleri (leaf- flower), Dianthus balansae (leaf- flower), Alyssum pateri subsp. pateri (seed) and Scabiosa columbaria subsp. paphlagonica (leaf) extracts that were tested.
