Abstract
用水提法和醇提法制备苏铁蕨(Brainea insignis)、华南紫萁(Osmunda vachellii)、狗脊蕨(Woodwardia japonica)和乌毛蕨(Blechnum orientale)的根状茎的提取液,应用纸片扩散法和试管二倍稀释法测定了各提取液对11种常见致病菌的抑菌圈、最低抑菌浓度(MIC)和最低杀菌浓度(MBC).结果表明,各提取液(1 g生药/mL)对表皮葡萄球菌、枯草芽孢杆菌、金黄色葡萄球菌及李斯特菌4种革兰氏阳性菌有明显抑制作用,对表皮葡萄球菌的抑制作用尤为明显,且醇提液的抑菌效果优于水提液;对大肠埃希氏菌等革兰氏阴性菌则无抑制作用.在4种贯众原植物中,苏铁蕨对革兰氏阳性菌的抑制活性最强.
