| 摘 要： | 目的]研究不同溶剂提取的薄荷（HERBA MENTHAE HAPLOCLYCIS）浸提物的抑菌效果,以期为优化薄荷提取工艺,减少2次污染,为薄荷进一步开发利用提供新途径。方法]采用琼脂扩散法测定不同溶剂提取的薄荷浸提物对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌、沙门氏菌的抑菌活性。结果]不同溶剂提取的薄荷浸提物对4种指示菌均具有的明显的抑菌作用;不同溶剂提取的薄荷浸提物的抑菌能力也不同,其中无水乙醇的薄荷浸提物的抑菌效果最好;薄荷浸提物的抑菌能力受到菌种的影响,相同的薄荷浸提物对不同菌种的抑制能力并不相同。结论]用无水乙醇的薄荷浸提物的抑菌效果最好。

| Abstract: | Objective] The research aimed to study the antimicrobial activities of different solvent extracts from HERBA MENTHAE,so as to optimize the extraction technology,decrease the second pollution and provide a new way for further exploitation and utilization of food industry.Method] Agar diffusion method was performed to determine the antimicrobial activities of different solvent extracts from HERBA MENTHAE against Escherichia coli,Staphylococcus aureus,Bacillus subtilis,Salmonella.Result] Different solvent extracts from HERBA MENTHAE had obvious antimicrobial activities against 4 indicator bacteria,in which absolute ethyl alcohol extracts performed the best.As for the same extract,the antimicrobial activities were varied for different strains.Conclusion] Absolute ethyl alcohol extracts had the best antimicrobial activity. |
