采用水煎煮法和乙醇回流提取法对苦参及其炮制品进行提取,采用牛津杯法测定金黄色葡萄球菌和大肠杆菌的体外最小抑菌浓度(MIC),研究不同提取方法、炮制方法对苦参的抗菌效果.结果表明,醇提液中生品提取液和醋炙品提取液对金黄色葡萄球菌的抑制效果较好,而对大肠杆菌的抑菌效果最好的是生品提取液,MIC值均为0.0125 g/mL;水提液中炒焦品提取液对金黄色葡萄球菌和大肠杆菌的抑菌效果较好,MIC值分别为0.1和0.2 g/mL.其中醇提液抑菌效果较水提液抑菌效果好;醇提液对大肠杆菌的抑制效果好于金黄色葡萄球菌;水提液对金黄色葡萄球菌的抑制效果好于大肠杆菌.因此,苦参生品及不同炮制品的醇提液和水提液对金黄色葡萄球菌和大肠杆菌均有抑菌效果.
