Abstract
The present study aimed at evaluating the antibacterial activity of methanol extract of Ruta chalapensis, L., (Rutaceae), Quercus infectoria Oliver., (Fagaceae) and Canthium parviflorum Lam., (Rubiaceae) against Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Klebsiella oxytocoa, Klebsiella pneumoniae and Proteus mirabilis. The experiment was carried out using disc diffusion method. The results revealed that the methanol extract of aerial parts of Ruta chalepensis (L) presented the highest zone of inhibition against tested pathogens. Other plants showed significant zone of inhibition.
Keywords: Ruta chalapensis, (L) Quercus infectoria (Oliver), Canthium parviflorum, (Lam) antibacterial activity and zone of inhibition
