The antimicrobial activities of the extracts of ethyl acetate, chloroform, methanol, ethanol and acetone Silene laxa Boiss. & Kotschy and Silene caramanica Boiss. & Heldr were studied by disc diffusion method. These extracts were tested against seven bacteria and one fungus, which revealed various levels of antimicrobial activity. The ethanol extracts of Silene laxa leaves showed the best antibacterial activity against Pseudomonas aeruginosa, Enterobacter cloacae, Bacillus megaterium (15mm 30 µl-1). The chloroform extracts of S. laxa branches displayed the best antibacterial activity against E.cloacae (16mm 30 µl-1). The ethyl acetate extracts of S.laxa fruits showed the best antibacterial activity against B.megaterium and E.cloacae (15mm 30 µl-1). The methanol extracts of
S. laxa leaves showed the best antibacterial activity against Staphylococcus aureus (18 mm 30 µl-1). The methanol extracts of S. laxa fruits showed the best antibacterial activity against B.megaterium (14mm 30 µl-1).
