Article history: Received on: 05/02/2014 Revised on: 26/02/2014 Accepted on: 19/03/2014 Available online: 27/05/2014 The present study was aimed to assess the plants antimicrobial effects such as Tamarisk, March, acetone and mango kernel. The aqueous and ethanol extract of the plants and also its smoke was prepared in concentrations of 50 and 25 mg/mL. The bacteria Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Pseudomonas aeruginosa, Candida albicans, Enterococcus faecalis were cultured by linear method. Impregnated extract discs were seeded onto the medium and the diameter of inhibition zone was measured following incubated for 24 h. The mango kernel extract by ethanol showed maximum inhibition zone diameter. Despite the weak antibacterial effect of aqueous and ethanol extract of Tamarix, Smoke extract of this plant shows good antimicrobial properties. Different extracts of March showed antimicrobial effects only on Candida albicans. Aqueous and ethanol extracts of acetone did not show significant effects.
