本试验采用滤纸片扩散法测定了连翘的花、叶片、枝条、果实（分青翘和老翘）的乙醇提取物对三种细菌性病害大肠杆菌（Escherichia coli）、金黄色葡萄球菌（Staphylococcus aureus）、枯草芽孢杆菌（Bacillus subtilis）和3种真菌病害青霉菌（Penicillium）、葡萄灰霉菌（Botrytis cinerea）和黄曲霉（Aspergillus flavus）进行了抑菌效果的对比和分析。用液体悬浮培养法分别测定了连翘不同部位的乙醇提取物对3种细菌的最小抑菌浓度（MIC）。试验结果表明：连翘不同部位的乙醇提取物对供试细菌均表现出有较强的抑菌作用，其中果实中青翘提取物的抑菌作用最强、老翘和叶片的抑菌作用也比较强，且两者区别不大，枝条提取物的抑菌作用最弱；对3种供试真菌所有供试部位提取物的抑菌效果均比细菌差。不同部位的乙醇提取物对不同细菌的最小抑菌浓度（MIC）则表现较大差异。

In this experiment Filter paper dispersion method was used to determine antibacterial effects about the ethanol extracts of different parts of Forsythia suspensa. The minimum inhibitory concentrations(MIC) of different parts of Forsythia suspensa. were determined by the Liquid suspension culture method.The results show that the ethanol extracts of different parts of Forsythia suspensa have certain bacteriostatic activity on the tested bacteria . Testing of bacteriostasis shows that strongest bacteriostasis is the extracts of ripening fruits.
