[Objective] To study anti-bacterial characteristics of bamboo leaves extracts from Pleioblastus kongosanensis. [Method] The water extract, petroleum ether extract, ethyl acetate extract and n-butanol extract of P. kongosanensis bamboo leaf were adopted to study the antibacterial activity on Escherichia coli, Bacillus subtilis, Staphylococcus aureus, yeast, Aspergillus flavus, Penicillium chrysogenum. [ Result ] The results showed that, the n-butanol extract and ethyl acetate extract have a certain inhibitory effect on 3 kinds of bacteria, the antibacterial effect of water extract and petroleum ether is not obvious; n-butyl alcohol extract have a bacteriostatic effect on 3 species of fungi. [ Conclusion] The study can provide theoretical basis for application of bamboo leaf extracts in anti-bacteria.%[目的]研究黄条金刚竹叶提取物的抑菌活性.[方法]以黄条金刚竹叶的水提取物、石油醚提取物、乙酸乙酯提取物和正丁醇提取物分别对大肠杆菌(Escherichia coli、枯草芽孢杆菌(Bacillus subtilis)、金黄色葡萄球菌(Staphylococcus aureus)、啤酒酵母(Saccharomycescarlsbergensis)、黄曲霉(Aspergillus.flavus)、产黄青霉(Penicillium chrysogenum)6种菌进行抑菌活性研究.[结果]试验表明,黄条金刚竹叶的正丁醇提取物和乙酸乙酯提取物对3种细菌都有一定的抑菌效果,水提取物和石油醚提取物对细菌的抑菌效果不明显；正丁醇提取物对3种真菌都有一定的抑菌效果.[结论]研究可为竹叶提取物抑菌性的应用提供理论依据.
