| 摘 要： | 为研究蓼科植物水蓼、火炭母体外抑菌效果,制备水煎煮液,测定其对枯草芽胞杆菌、大肠埃希菌、金黄色葡萄球菌、黑曲霉、青霉、酿酒酵母的抑菌圈直径、最小抑菌浓度及灭菌前后水煎煮液抑菌效果的变化。结果表明：当水蓼液浓度大于0.6 g/mL,火炭母液浓度大于0.2 g/mL时,2者对细菌的抑菌效果均依次为：金黄色葡萄球菌〉大肠埃希菌〉枯草芽胞杆菌。2种水煎煮液对3种真菌无抑制作用。火炭母液对3种细菌的最小抑菌浓度分别为1/8、1/16和1/64 g/mL,都比水蓼液的结果1/4、1/8和1/16 g/mL低。药液经121℃高压蒸汽灭菌处理后,水蓼液对3种细菌的抑制作用有所增强,火炭母液则对金黄色葡萄球菌的抑制作用有所增强。2种水煎煮液对3种细菌均有不同程度的抑制作用,可考虑以其为原料进行植物源抗菌剂的开发,拓宽其应用领域。

| Abstract: | Antibacterial effects of two species of Polygonaceae of Polygonum hydropiper(Ph) and Polygonum chinense(Pc) were studied in vitro with their water decoction,and determined their inhibitory rings,minimal inhibitory concentration(MIC) and the antibacterial effects before and after sterilization against Bacillus subtilis(Bs),Escherichia coli(Ec),Staphylococcus aureus(Sa),Aspergillus niger(An),Penicillium citrinum(Pc),and Saccharomyces cerevisiae(Sc).The results indicated that the antibacterial effects of these... |
