Broad spectrum antidermatophytic drug for the control of tinea infection in human beings.During antifungal evaluation of various plant extracts, free and bound flavonoids of Piper betle were found to be most effective as an antidermatophytic against human pathogenic dermatophytes Trichophyton rubrum, Trichophyton mentagrophytes, Microsporum gypseum and Candida albicans. Dermatophytic fungi cause both superficial and internal mycoses. These mycoses, although normally not lethal, are unpleasant and difficult to cure and cause considerable financial losses. Earlier workers prove that a ...201121929713
