Ethanol extracts of nine medicinal herbs were measured by agar diffusion method with bacteria in-cluding Lactobacillus, Pseudomonas, Enterobacteriaceae and Brochothrix thermosphacta to determine the anti-bacterial activity of the herbs and the optimal combination. The results showed that ethanol extracts of all nine herbs were of antibacterial activity and the diameters of their inhibition zone range from 8mm to 16mm. The re-sults also revealed that Schisandra, Pomegranate husk, Rhizoma coptidis and Polygonum cuspodatum had wide-spectrum antimicrobial properties, and the 1∶1∶1 composite liquid of extracts from Schisandra, Pome-granate husk and Polygonum cuspodatum had a better antibacterial activity to the 4 kinds of bacteria. The study provides ground for the application of Chinese herbal medicine to the preservation of meat products.%选择9种中草药乙醇提取液,以热杀索丝菌、肠杆菌、假单胞菌和乳酸菌为供试菌,采用打孔扩散法测定中草药的抑菌效果,并选择抑菌效果较好的中草药保鲜剂配方。结果表明：这9种中草药提取物均具有抑菌效果,抑菌圈直径为8~16 mm,其中五味子、石榴皮、黄连和虎杖4种中草药具有广谱抑菌性,且五味子、石榴皮和虎杖的1∶1∶1复配液对4种供试菌的抑菌效果最好,为中草药在肉制品保鲜方面的应用提供依据。
