Antibacterial activity of aqueous and alcoholic extracts of 34 Indian medicinal plants against some Staphylococcus species

Otuzdört adet Hindistan'a ait tıbbi bitkinin sıvı ve alkolik ekstraktının bazı Staphylococcus türlerine karşı antibakteriyal aktivitesi

Özet

Hindistan’da yetişen Yirmi sekiz farklı familyaya ait 34 farklı tıbbi bitkinin üç Staphylococcus species viz. Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus subşava bakterisi üzerine sıvı alkolik ektraktların antibakteriyal aktivitesi agar disk diffüzyon ve agar well diffüzyon yöntemi ile çalışılmıştır. En hassas bakteri S. aureus olarak belirlenmiştir. Woodfordia fruticosa bitkisinin methanol ekstraktı iyi antibakteriyal aktivite göstermiştir. In vitro duyarlılık testi Staphylococcus türlerine karşı standart antibiyotikler kullanılarak yapılmıştır.

Abstract

Thirty-four Indian medicinal plants belonging to 28 different families were screened for potential antibacterial activity against 3 Staphylococcus species, namely Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus subflava. Antibacterial activity of aqueous and alcoholic extracts was performed by agar disc diffusion method and agar well diffusion method. The alcoholic extracts were more active than aqueous extracts for all the plants studied. The most susceptible bacterium was S. aureus. The methanol extract of Woodfordia fruticosa showed the best antibacterial activity. The in vitro susceptibility testing of the studied staphylococcus strains was done against standard antibiotics.
