Abstract:The inhibition effects of 6 kinds of chinese herbal extracts against fungi(Mucor and Penicillium) causing decay on postharvest peach were studied in this paper.The 6 kinds of chinese herbal were glycyrrhiza,alpinia officinarum,phellodendron,asiatic moonseed,leaf of moxa and forsythia.The antibacterial effects of different chinese herbal extracts were comparatived by growth rate method and inoculation of spore suspension on peaches.The species of chinese herbal which had good inhibitory effects were selected.And the minimal inhibition concentration(MIC) and minimal bactericidal concentration(MBC) of chinese herbal which had good inhibitory effects were investigated by dilute with grads.The results showed that:different chinese herbal extracts had different inhibitory effects against fungi causing decay on postharvest peach.Glycyrrhiza and forsythia were the better kinds which against the Mucor and Penicillium in these 6 kinds of chinese herbal.Alpinia officinarum and phellodendron were the kinds with general inhibition.Leaf of moxa and asiatic moonseed were the weak inhibition kinds.The MIC of glycyrrhiza and forsythia extracts on Mucor all were that amounts of extracts in medium(v/v) were 25%,the MBC of glycyrrhiza and forsythia extracts on Mucor were 50%.And on Penicillium,the MIC of glycyrrhiza and forsythia extracts all were that amounts of extracts in medium(v/v) were 12.5%,the MBC of lycyrrhiza and forsythia extracts on Penicillium were 25%.
