摘　　要：观察了中药抗鸡源产气荚膜梭菌的药效。从初步诊断为坏死性肠炎的病鸡中分离鉴定出产气荚膜梭菌,选用6种中药水提取物对鸡源产气荚膜梭菌进行体外抑菌试验测定其最小抑菌浓度(MIC值)。结果表明,在6种中药水提取物中,黄芩、黄连的抑菌效果最好,其MIC值均为3.9 mg/mL,而穿心莲和板蓝根仅在高浓度时具有抑菌作用,具体的抑菌成分和作用机制有待进一步研究。The in vitro inhibitory effects of Chinese herb extracts on Clostridium perfringens were observed.The minimum inhibitory concentrations（MIC） of six Chinese herb extracts against Clostridium perfringens from chicken were determined.The result showed that the MIC of Scutellaria baicalensis and Coptidis Rhizoma were 3.9 mg/mL,while Andrographis Paniculata and Radix Isatidis had inhibitory effects only at high concentrations.
