The Investigation of Antibacterial Effects of Salvia Sahendica Extracts on Some Pathogenic Bacteria

Abstract

Background: The salvia plant is one of the Lamiacea family members, that is being cultiurated all over the world. In Iran almost all spices of this plant could found, that are used for medical, food industry and parfumers production. Salvia sahendica genus is the member of this family, that its antibacterial effects on Klebsiella pneumonia, Staphylococcus aureus and Pseudomonas aeruginosa have been investigated. Methods: In this study are used standard strains of Pseudomonas aeruginosa (ATCC 27852) Staphylococcus aureus, (ATCC 25923) and, Klebsiella pneumonia (ATCC 3583). Salvia was provided from Tabriz mall and was powdered. Then this powder was suspended with ratio 1:10 with Metanol, Aceton, Chloroform, Hexan, Ethyl acetate and water. After 24h extractions isolated and concentrated with distillated in vacuum system. Which of bacteria were cultured to over night in Mohler Hinton agar medium, then compared with 0.5 macfarland. In continue extraction were tested by used of well assay method and then the diameter of zone measured. Experiments repeated tree times and the average of data obtained. In each of tests we had a control from special solvent. Results: Regarding to the results, all of salvia sahendica extractions showed antibacterial activity on Staphylococcus aureus, Pseudomonas aeruginosa and. That regarding Klebsiella pneumonia, Ethanol, Chloroform, Ethyl acetate, Hexan, and regarding Staphylococcus aureus Metanol, Aceton, Chloroform, Hexan, Ethyl acetate and Pseudomonas aeruginosa only Chloroform this plant has antibacterial effects. Chloroform extraction of salvia shows the most antibacterial activity (with the biggest diameter of antibacterial zone). Conclusion: Regarding the carried out study it could be noted that for inhibition and destroying Staphylococcus aureus and Klebsiella pneumonia, plants effects extraction could be used.
