ABSTRACT
Objective: To determine the antimicrobial activity and entity of several local herbal plants against Acintobacters isolated from trauma patients admitted to a Level-I trauma center
Methods: The antibacterial activities of the Satureja bachtiarica oil and some selected Iranian medicinal plants [Artemisia sieberi and Tanacetum dumosum belonging to the Asteraceae/Compositae; Salvia mirzayanii and Mentha mozaffarianii belonging to the Lamiaceae/Labiatae] were assayed on A. baumannii by microdilution and agar disc diffusion methods. Having obtained the acceptable antibacterial data, the shade-dried aerial parts of the plants were extracted by hydrodistillation method using Clevenger apparatus according to European pharmacopeia for 3 h. The analysis of S. bachtiarica essential oil accompanied by other herbal drug oils were performed by using GC/FID and GC/MS methods
Results: Outcomes revealed that the S. bachtiarica essential oil exhibited the potent antibacterial capability against Acinetobacter strains in comparison with Colistin, as a positive control. For S. bachtiarica, the growth inhibition zone and minimum inhibitory concentration [MIC] values were 21 mm and 0.5 mg/ml, while, for Colistin, the data were in order: 8 mm and 0.016 mg/ml. Consequently, GC/MS outcomes demonstrated that the major components of the essence were carvacrol [48.6%], followed by p-Cymene [16.6%], ã-terpinene [6.9%] and linalool [5.3%]
Conclusion: Based on the considerable inhibitory activity against nosocomial infections by essential oil of S. bachtiarica, it could be considered as the suitable candidate in the food industry and pharmaceutical uses
