Abstract

Herbal teas are widely consumed in Turkey. This study aimed to evaluate the antimicrobial activity of methanol, acetone, and aqueous extracts of endemic Sideritis galatica plant collected from Afyonkarahisar. For this purpose, the effect of different concentrations (2.5%, 5%, 10%, 20%) of these extracts on L. monocytogenes, B. cereus, S. aureus, E. faecalis, E. coli, E. coli O157, S. typhimurium, C. albicans were investigated by the disk diffusion method. Methanol extract showed antimicrobial activity against all of the tested microorganisms. Also, acetone and aqueous extracts showed antimicrobial activity against all of the tested microorganisms except E. faecalis (for acetone extract), E. coli and E. coli O157 (for aqueous extract). Consequently, S. galatica as an endemic plant showed antimicrobial activity especially at high concentrations against tested microorganisms.

Endemik Sideritis galatica bitkisinin antimikrobiyal etkisinin araştırılması

Abstract

Bitkisel çaylar Türkiye'de yaygın olarak tüketilmektedir. Bu çalışmada Afyonkarahisar'dan toplanan endemik Sideritis galatica bitkisinin metanol, aseton ve sulu ekstraktlarının antimikrobiyal aktivitesi değerlendirildi. Bu amaçla, bu ekstraktların farklı konsantrasyonlarının (% 2,5, % 5, % 10, % 20) L. monocytogenes, B. cereus, S. aureus, E. faecalis, E. coli, E. coli O157, S. typhimurium, C. albicans disk difüzyon yöntemi ile araştırıldı. Metanol ekstraktı test edilen tüm mikroorganizmalara karşı antimikrobiyal aktivite gösterdi. Ayrıca, aseton ve sulu ekstraktlar, E. faecalis (aseton ekstraktı için), E. coli ve E. coli O157 (sulu ekstrakt için) hariç test edilen tüm mikroorganizmalara karşı antimikrobiyal aktivite gösterdi. Sonuç olarak, endemik bir bitki olarak Sideritis galatica, test edilen mikroorganizmalara karşı özellikle yüksek konsantrasyonlarda antimikrobiyal aktivite gösterdi.
