Volatile oil composition and antimicrobial activity of two Thymus species
Background: Medicinal plants have potential for using as antimicrobial agents against pathogens. In genus Thymus (Lamiaceae), phenolic compounds with terpene origin are responsible of these effects. Objective: Evaluated essential oil constituents and antimicrobial activity of Thymus daenensis compared with Thymus vulgaris. Materials and methods: Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans and Aspergillus niger were used for antimicrobial activity assay with using disc diffusion technique. Volatiles oils compositions were analyzed by GC/MS. Results: Escherichia coli was resistant to essential oils. Essential oil obtained from T. daenensis showed better antimicrobial activity than with T. vulgaris. Thymol (84.45%) and carvacrol (46.62%) were the main components of T. daenensis and T. vulgaris respectively. Conclusion: The results showed that T. daenensis was more effective and could be an alternative for T. vulgaris. In addition, these essential oils could be used as natural antimicrobial agents.
