In this study performed on six endemic plant species, antimicrobial activity was observed in Campanula
lyrata subsp.lyrata and Abies nordmanniana subsp. bornmuelleriana plants. 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 for Staphylococcus aureus, and the minimum inhibitory
concentration (MIC) of Abies nordmanniana subsp. bornmuelleriana (leaf) extract was found to be > 314
mg/ml for B. 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.
