探讨大黄的体外抑菌作用。采用圆纸片扩散实验来检测大黄对金黄色葡萄球菌、大肠杆菌、痢疾杆菌、绿脓杆菌及伤寒沙门菌的抑菌效果。结果显示大黄对上述细菌均有一定的抑制作用。其中对金黄色葡萄球菌,痢疾杆菌,伤寒沙门菌有很强的抑制作用,为高敏;对绿脓杆菌的抑菌作用次之,为中敏;对大肠杆菌的抑菌作用较弱,为低敏。 To investigate the antibacterial effect of rhubarb in vitro. The inhibition effect of rhubarb on Staphylococcus aureus, Escherichia coli, Shigella dysenteriae, Pseudomonas aeruginosa and Salmonella typhimurium was tested by round disk diffusion test. The results showed that rhubarb on the above bacteria have a certain inhibitory effect. Among them, Staphylococcus aureus, Shigella dysenteriae, Salmonella typhi has a strong inhibitory effect, high sensitivity; Pseudomonas aeruginosa bacteriostatic second, as sensitive; bacteriostatic effect on Escherichia coli is weak, low Min.
