摘要
目的:研究毛竹提取物和苦竹提取物的抗菌活性,为口腔抗菌印模材料的研制奠定实验基础。方法:采用琼脂稀释法药物敏感试验,测定毛竹提取物和苦竹提取物对金黄色葡萄球菌ATCC25923、大肠埃希菌ATCC25922和变异链球菌ATCC25175的最小抑菌浓度(MIC)。结果:毛竹提取物对金黄色葡萄球菌的最小抑菌浓度(MIC)为3.125mg/mL,对大肠埃希菌和变异链球菌的最小抑菌浓度均为6.25mg/mL;苦竹提取物对金黄色葡萄球菌、大肠埃希菌和变异链球菌的最小抑菌浓度(MIC)分别为3.125mg/mL、6.25mg/mL和12.5mg/mL。结论:两种竹提取物对供试菌均具有抑制作用。
AIM：To examine the antibacterial activity of the extracts from Phyllostachys pubescens and Pleioblastus amarus. METHODS：The minimal inhibitory concentrations （ MIC） of Phyllostachys pubescens and Pleioblastus amarus extracts to Staphylococus aures ATCC25923,Escherichia coli ATCC259 and Streptococcus mutans ATCC25175 were determined by agar dilution method. RESULTS：The MIC of P. pubescens extracts was 3. 125mg/mL against S. aures,and 6. 25mg/mL against E. coli and S. mutans; while the MIC of Pleioblastus amarus extracts was 3. 125mg/mL against S. aures,6. 25mg/mL against E. coli ans 12. 5 mg/mL against S. mutans. CONCLUSION：Both Phyllostachys pubescens and Pleioblastus amarus extracts showed bacterial inhibitory effects against the tested bacterial strains.
