[Objective] 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,Staphyloccocus aureus Rosenbach,Bacillus subtilis Cohn and Salmonella.[Result] Different solvent extracts from HERBA MENTHAE had obvious antimicrobial activities against 4 indicator bacteria,in which absolute ethanol extracts performed the best.As for the same extract,the antimicrobial activities were varied for different strains.[Conclusion] Absolute ethanol extracts had the best antimicrobial activity.
