摘　　要：目的:探讨玉米须的体外抗菌活性。方法:采用琼脂扩散法和试管连续稀释法测定玉米须对常见致病菌和条件致病菌的体外抗菌活性及最低抑菌浓度(MIC)。结果:(1)玉米须对金黄色葡萄球菌和乙型溶血性链球菌皆有明显的抗菌活性,抑菌圈直径分别为21mm和16mm。对金黄色葡萄球菌的最低抑菌浓度为0.5g/m l。(2)玉米须对大肠埃希菌、福氏志贺氏菌、伤寒沙门氏菌、铜绿假单胞菌无抗菌活性。结论:玉米须对金黄色葡萄球菌和乙型溶血性链球菌有较好的体外抑菌活性。Objective： To research antimicrobial activity of maize silk. Methods：By methods of agar plate diffusions and tube continuous dilvtion mensurating antimicrohial activity and minimal inhibitory concentration（MIC） of maize silk against pathogen and conditioned pathogen. Results： （ 1 ） maize silk has antimicrobial activity against S. aureus , 13-hemolytic streptococcus, the diameter of bacteriostatic circle is 21 and 16 millimetre . The antimicrohial activity against S. aurcus is 0.5g/ml. （2） maize silk has not antimicrobial activity on E. coli, S. flexneri, Salmonella Typhi, P. aeruginosa. Conclusion： maize silk has good antimicrohial activity against S. aureus, β-hemolytic streptococcus.
