Title

Investigation of Chemical Composition, Antibacterial and Antioxidant Activity of Thymus daenensis and Thymus eriocalyx Essential Oils against Human Pathogenic Bacteria

Pages

Abstract

 Introduction: Plant Essential oils can be used as alternative agents for the treatment of antibiotic-resistant Pathogenic bacteria. This study aimed to investigate the Chemical composition, Antibacterial, and antioxidant activity of Thymus eriocalyx and Thymus daenensis Essential oils against Gram-positive and Gram-negative human Pathogenic bacteria. Methods: The aerial part of Thymus eriocalyx and Thymus daenensis in the full flowering stage were collected from West Azerbaijan Province (Urmia), Iran, in 2014. We obtained the Essential oils using a Clevenger device. The disc diffusion method was used to determine the Antibacterial activity of the Essential oils against 15 Grampositive and Gram-negative PTCC and ATCC bacterial standards. Minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) were measured by microdilution broth method in 96-well plate and free radical scavenging activity by 2, 2-diphenyl-1-picrylhydrazyl. Chemical analysis of the Essential oils performed out by gas chromatography connected to Mass spectrometry. Results: Eleven (94. 06%) and seven (90. 76%) compounds were identified in T. eriocalyx and T. daenensis Essential oils, respectively. The major components of T. eriocalyx Essential oil were thymol (37. 8%) and α-terpineol (14. 91%), and of T. daenensis were thymol (52. 36%) and carvacrol (16. 72%). T. eriocalyx Essential oil showed the highest activity against B. cereus with MIC of 0. 93 μ g mL-and MBC of 1. 87 μ g mL-. The most potent radical scavenging activity was also obtained for T. daenensis Essential oil. Conclusion: Essential oil components of T. eriocalyx and T. daenensis may have the potential to be used as antimicrobial agents against antibiotic-resistant Pathogenic bacteria.
