Abstract: Essential oils of several spices and herbs have shown strong antimicrobial activity and exhibited important prospect in exploitation of natural fungicides. This study has compared the inbibitory response of some important postharvest fungi to thec lovee ssentialo ils extractedr espectivelyb y supercriticalC O2,s team distillationa nd direct-waterd istillation.C lovee ssential oils showed apparent inhibitory effect on main pathogens to cause postharvest decay of grape, jujube, peach and garlic shoot. 600mgL clove essential oil could wholly inhibit the growth of Botrytis cinerea, Alternaria alternate and Penicillium expansum. 500mgL clove essential oil could inhibit the growth of Botytis cinerea to cause decay of peach and garlic stem by 79.3% and 85.7%, respectively. Among the three extraction methods, the order of antimicrobial efficacy was shoot distillation, supercritical CO2 extraction,a nd direct-waterd istillation.
