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 were extracted 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 three types of bacteria: Bacillus cereus, Escherichia coli, and Pseudomonas. The results proved that the EOs of rosemary were influential against bacteria and gave minimum inhibitory concentration (MIC). The MIC values were 37 μg/ml for E. coli, 69 μg/ml for Pseudomonas, and 20 μg/ml for B. cereus. Results found that Pseudomonas was less sensitive for these oils. Conclusion: The EOs of Rosemary can be used in the pharmaceutical industry for the production of new synthetic agents in the treatment of bacterial disease caused by these three types of bacteria.
