Antimicrobial activity of some Mentha species.

Species Name	Sample Used	Microorganisms	Activities	References
M. aquatica L.	Essential oil	Staphylococcus aureus, Escherichia coli, Bacillus sp., and Candida sp.	Showed activity against S. aureus, E. coli, and Bacillus sp., but no result against Candida sp.	[65]
M. arvensis L.	Ethanol extract	Acinetobacter baumannii	Results showed 34.5 mm inhibition use at 100 μg/mL	[85]
M. ervine L.	Essential oil, pulegone, isomenthone and menthone was used	S. aureus, S. caprae, Enterococcus faecalis, E. faecium, E. hirae, E. coli, Salmonella braenderup, S. typhimurium, S. choleraesuis, Klebsiella pneumonia, Acinetobacter baumannii, Pseudomonas aeruginosa, and Listeria monocytogenes strains	Showed variation in activity against Gram positive and Gram-negative strains, but overall inhibition activity was significant as compared to control	[86]
M. arvensis var. piperascens Malinv. ex Holmes	Essential oil	Salmonella enteritidis, E. coli, Clostridium Perfringens, Campylobacter jejuni, and Salmonella species	Significant antibacterial activity against all strains specifically Salmonella species and C. jejuni (inhibition zones more than 40 mm)	[87]
M. × piperita L.	Essential oil	Aeromonas spp.	High antibacterial activity was shown by the essential oils, ranging from 1.250 to 16.67 μL/mL	[88]

Essential oils, Menthone, carvone Menthol, and piperitenone oxide	S. aureus, E. coli, B. subtilis, Aspergillus flavus, Alternaria solani, Aspergillus niger, Alternaria altarnata, Rhizopus solani, Fusarium solani, and Rhizopus sp.	Among these, menthol showed high antimicrobial activity, with the inhibition zone ranging from 19–33 mm	[82]
M. itrate Ehrh.	Essential oils	E. coli, K. pneumonia, Salmonella typhimurium, Staphylococcus epidermidis, Streptococcus mutans, P. aeruginosa, and S. aureus	Average activity was recorded from between 10–15 mm inhibition zone against different strains, but essential oil showed an inhibition zone of more than 15 mm against S. epidermidis	[89]
M. haplocalyx Briq.	Methanol extract	E. coli	Potential activity against E. coli	[90]
M. pulegium L.	Essential oil	S. aureus	Significant activity was observed as compared to control	[91]
M. requienii Bentham	Essential oil	Aspergillus fumigatus, C. albicans, Fusarium spp., and Rhodotorula sp.	Revealed sufficient inhibition against molds and yeasts, ranging from 40 mm to 70 mm	[92]
