目的研究甘蔗叶提取物的抑菌作用。方法采用琼脂稀释法对甘蔗叶提取物进行体外抑菌试验。结果甘蔗叶提取物对金黄色葡萄球菌、大肠埃希氏菌、铜绿假单胞菌、伤寒沙门氏菌、枯草芽孢杆菌和肺炎克雷伯氏菌均有不同程度的抑制作用,对链球菌作用较差。其中,50%和70%醇提物作用效果较好。结论甘蔗叶提取物在体外有抑菌活性,在抑菌方面有一定的开发前景。
Objective To study the bacteriostasis of sugarcane leaf extract. Methods The antibacterial activity of sugarcane leaf extract in vitro was tested by agar dilution method. Results The sugarcane leaf extract had different inhibitory effects on Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Bacillus subtilis and Klebsiella pneumoniae, and had a poor effect on Streptococcus . Among them, 50% and 70% alcohol extract effect is better. Conclusion Sugarcane leaf extract has antibacterial activity in vitro and has certain development prospects in bacteriostasis.
