Antibacterial Activity of (Essential Oil) Against Pathogenic Bacteria and Determination of Chemical Composition of Essential Oils by Gas Chromatography-Mass Spectrometry Analysis in Four Regions of Kerman.

The use of medicinal plants has been considered due to increasing bacterial resistance to antibiotics. is a plant with high potential in medicine. The aim of this study was to evaluate the antibacterial activities and gas chromatography-mass spectrometry (GC-MS) analyses of the essential oil of from four regions in Kerman: Hezar Mountain, Laleh Zar, Bidkhan, and Rabor. The essential oil of this plant was extracted by Clevenger. The antibacterial activities were evaluated against three Gram-negative bacteria () and three Gram-positive bactria (). By disk diffusion method, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were determined. The composition of essential oil was identified by GC-MS analysis. In our study, most yield of essential oil of was 1.2% from the Laleh Zar region and the main components were Z-β-ocimene (25.4%) in Laleh Zar, linalool (17.7%) in Hezar, Z-β-ocimene (18.5%) in Bidkhan, and β-pinene (10.5%) in the Rabor region. Maximum inhibition zone by the essential oil from region Bidkhan was observed against (30 mm). The MIC value for collected from Laleh Zar was 1.25 mg/ml against and The results of this study confirm that the significant antibacterial effects of and make it a valuable compound in essential oils for pharmaceutical use and a good replacement for chemical antibiotics. Environmental conditions can result in a difference in yields and components; this can be considered significant potential for this plant.
