Effects of Different Solvents to Extract Phytochemical Materials of Rhazya stricta Against Salmonella typhimurium Activity

Background: The use of plant extracts prepared from medicinal plants is common in the developing countries. Meanwhile, due to resistance microorganisms antibiotics, researchers are looking discover new antimicrobials. Medicinal play an essential role this regard. Objectives: This study was aimed at investigating antimicrobial properties various Rhazya stricta against Salmonella typhimurium. Methods: Methanolic, aqueous, ethanolic, hydroalcoholic, and ethyl acetate R. were prepared. typhimurium strains isolated poultry feces. microdilution method used determine minimum inhibitory concentration (MIC) bactericidal (MBC) plant. diameter growth inhibition zone using determined Whatman paper. Results: lowest MIC S. obtained hydroalcoholic solvent with 3.1 ppm. most effective extraction inhibit type average 12.25 mm, followed by ethanolic extract a 12.12 mm. Conclusions: According results research increasing synthetic antibacterial substances, it seems that help solvent, can be considered eliminating some bacteria, including
