Abstract:Essential oils were extracted by steam distillation from the thirteen incense spices. The antimicrobial activity of essential oils to usual bacteria, fungi and yeasts were studied through testing the inhibition zone, minimal inhibitory concentrations and effect of gaseous corrosion. The results showed that the antimicrobial effects of essential oil were: fungus> bacteria > yeast. Thirteen-spices essential oils had gaseous corrosion and practical application potential in food preservation
