Ziziphoraclinopodioides is a plant from Lamiaceae family. In this research the antimicrobial effect of Ziziphoraclinopodioides essential oil (at 0.05%) and extract (at 0.4%) were studied on Salmonella enterica, Staphylococcus aureus and Saccharomyces cerevisiaein mayonnaise during storage timeat 4oC. Results showed that the antimicrobial effect of Z.clinopodioidesessential oil was higherthan the extract. This effect increased with increasingthe concentration rate. The Ziziphoraclinopodioides essential oil was able to inhibit both gram-positive and gramnegative 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.
