Abstract. Antimicrobial resistance has been an increasing problem in public health around the world. Natural plants can be utilised as an important source for antimicrobial agents to be used in place of synthetic drugs due to their costs and side effects. Thus, it is essential to find out new, effective, safer natural antimicrobial products. In the present study, in vitro antibacterial activities of different traditional plants against pathogen microorganisms were tested. The extracts of all plants were prepared in four different solvents (ethanolic, methanolic, hexane and aqueous) and then used for disc–diffusion method. Each assay was repeated in triplicate. The analysis was carried out using two–way analysis of variance (ANOVA). The highest antimicrobial activities were obtained by methanolic extracts of Sorbus domestica against E. coli, while Methanolic Extracts of Epilobium angustifolium were effective against Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa. In addition, Hexanic Extract of Tragacanth gum and S. domestica had high antibacterial activity against K. pneumoniae and P. aeruginosa, respectively.
