新疆天山八种蕨类植物体外抑菌活性初探

Preliminary Studies on the External Bacteriastasis of Some Pteridophytes from Xinjiang

目的 筛选新疆天山蕨类植物抑菌活性的种类及明确药用部位 ,为合理开发提供科学依据。方法 用双层平板打孔法和滤纸片法 ,对 8种蕨类植物营养叶或孢子叶的乙醇提取液进行了抑菌试验。结果 8种植物对实验菌有不同程度抑制作用 ,其中 ,对大肠杆菌和金黄色葡萄球菌的作用最强 ,对枯草杆菌、绿脓杆菌和变形杆菌的作用较弱 ,而对白色念珠菌无任何抑菌作用。结论 新疆天山蕨类植物具有一定的抑菌作用。

Objective\ To find out some of the species of the Pteridophytes from Xinjiang which has bacteriostatic activities and to select their active medicinal parts, therefore to provide scientific basis for its exploitation and utilizatiaon. Method\ Agarose diffusion assay and filter paper antibacterial assay were used for the ethanol extractions of 8 Pteridophytes species' trophylles and sporophylles in order to test their ability of inhibiting the growth of the bacteria. Result\ All these 8 species of the Pteridophytes could restrain the growth of the different bacteria at different degrees. Among them the inhibitory effect of the Pteridophytes on the Escherichia coli and Staphylococcus oureus was the highest, on the Bacillus sabtilis and Pseudomonas aeruginosa was lower than that of the others .No bacteriostatic activities was found in the Condida albicans. Conclusion\ Exploitation and utilization of the Pteridophytes has broad prospects.
