摘要
将马齿苋黄酮类化合物作用于大肠杆菌、金黄色葡萄球菌和酵母菌,采用滤纸片法测定其抑菌效果,通过测定菌液中还原糖含量、可溶性蛋白质含量和电导率的变化情况,分析马齿苋黄酮类化合物的抑菌机理。结果表明,马齿苋黄酮类化合物主要是通过破坏细菌细胞膜,使其内容物外渗,从而达到抑菌目的。
The antibacterial efficiency of flavonoids from purslane against Escherichia coli,Staphylococcus aureus and Saccharomycetes were measured by filter-paper method.The changes of reducing sugar content,soluble protein content,conductivity in the bacteria solution were detected.The antibacterial mechanism of flavonoids from purslane was analyzed.Results showed that the antibacterial purpose of flavonoids from purslane was achieved by disrupting cell membrane and leaking cellular content.
