Allawi, Hind Mufeed Ewadh PY - 2018 VL - 15 IS - 1 SP - 53 EP - 56 JO - Medical Journal of Babylon مجلة بابل الطبية SN - 1812156X 23126760 AB - Background: Interest in Rosemary has increased due to the importance of being wide antimicrobial, anti-inflammatory, and antioxidant.Objective: This study aimed to evaluate the biological affectivities of essential oils (EOs) of rosemary against three types of bacteria.Materials and Methods: Chemical analyses were conducted using gas chromatography technique on the volatile oils of rosemary, which wereextracted by Clevenger. Results: The major contents of these oils were camphor (22.35%), camphene (1.85%), β-pinene (3.75%), sabinene(10.25%), limonene (7.64%), linalool (11.58%), and myrcene (2.14%). The biological affectivities of these oils were examined on threetypes of bacteria: Bacillus cereus, Escherichia coli, and Pseudomonas. The results proved that the EOs of rosemary were influential againstbacteria and gave minimum inhibitory concentration (MIC). The MIC values were 37 μg/ml for E. coli, 69 μg/ml for Pseudomonas, and 20μg/ml for B. cereus. Results found that Pseudomonas was less sensitive for these oils. Conclusion: The EOs of Rosemary can be used in thepharmaceutical industry for the production of new synthetic agents in the treatment of bacterial disease caused by these three types of bacteria.
