摘要
研究连翘乙醇提取物的抑菌活性。以金黄色葡萄球菌和大肠杆菌为实验菌株,通过比较和分析不同连翘提取物浓度下细菌生长曲线的变化来研究连翘的抑菌作用特点。结果发现0.01 g/ml的提取物对摇床培养的金黄色葡萄球菌生长具有较强的抑制作用;0.10g/ml的提取物对摇床培养的大肠杆菌生长具有一定的抑制作用。由此表明,连翘乙醇提取物具有明显的选择性抑菌作用。
To investigate the antimicrobial effect of Forsythia suspensa (Thunb) Vahl. Methods. To draw the growth curve of S. aureus and E. coli by de-ternining OD420,and to study the affect according to the change of the growth curve, Resuhs:0.01 g/ml extract of Forsythia suspensa( Thunb) Vahl.has obvious antimicrobial effect on S. aureus, and 0.10 g/ml extract of Forsythia suspensa (Thunb) Vahl. has some antimicrobial effect on E. coli. Conclu-sion:The ethanol Extract of Forspthia suspensa( Thunb)Vahl.has selective obvious antimicrobial effect.
