Numerous chemical compounds in plants with bioactive properties containing secondary metabolites are used in several industries such as pharmaceutical, chemical, cosmetic and especially in food industry. Recently, the existence of antioxidant and antimicrobial compounds in plants causes to take in researcher's interest. This study was designed to examine the in vitro antimicrobial and antioxidant activities of the essential oils of six herbs; Heracleum lasiopetalum Boiss., Satureja bachtiarica Bunge., Thymus daenensis Celak., Dracocephalum multicaule Benth., Kelussia odoratissima Mozaff., Thymus carmanicus Jalals and Satureja khuzestanica Jamzad.. The Essential oils were also tested for their antioxidant activities using DPPH assay. The antibacterial activity of the essential oil was tested by agar disc diffusion assay against Pseudomonas aeruginosa. The results showed that essential oils of

T. daenensis, T. carmanicus, S. khuzestanica and S. bachtiarica have effects highest antibacterial and the essential oils of T. carmanicus and S. bachtiarica were the most potent antioxidant.
