Abstract
Essential oil is the odorous and volatile products of plant secondary metabolism, has wide applications in folk medicine, food flavouring and preservation as well as in fragrance industries. Essential oils of spices and herbs were found to possess the strongest antimicrobial properties among many tested. In the present investigation the antimicrobial activity of essential oil from Mentha piperita have been screened against six isolates of antropophilic dermatophytes: Trichophyton rubrum, T. tonsurans, T. schoenleinii, T. mentagrophytes, Microsporum canis and M. fulvum. The antimicrobial efficiency of essential oil tested against the human pathogenic fungi (dermatophytes) was evaluated from clear inhibition zone. Maximum zone of inhibition was observed against Trichophyton rubrum followed by T. schoenleinii. For effective concentration of oil against dermatophytes, MICs and MFCs values ranged from 0.1 to 1.5 μl/ml. Both species of Microsporum responded inhibition above 1.2 μl/ml of oil.
