Ziziphora clinopodioides is a plant from Lamiaceae family. In this research the antimicrobial activity of Z. clinopodioides essential oil (at 0.05%) and extract (at 0.4%) were studied on Salmonella enterica, Staphylococcus aureus and Saccharomyces cerevisiae in mayonnaise during storage time at 4°C. Results showed that the antimicrobial effect of Z. clinopodioides essential oil was higher than the extract. This effect increased with increasing the concentration rate. The Z. clinopodioides essential oil was able to inhibit both gram-positive and gram negative bacteria and also the yeast. At the concentrations of Z. clinopodioides essential oil and extract we tested in the current study, we observed no unfavorable effect on the sensory parameters in mayonnaise.
