Screening of selected medicinal plants for in vitro antidermatophytic activity.J Mycol Med. 2013 Dec; 23(4):247-54.JM
Different solvent extracts of leaves of Achyranthes aspera, Aegle marmelos, Cleistanthus collinus, Curcuma aromatica and Strychnos nux-vomica were screened against dermatophytes viz., Trichophyton mentagrophytes, T. rubrum, Microsporum gypseum, M. canis and Epidermophyton floccossum var. nigricans. The mean zones of inhibition were between 7.1 and 26.5mm. Minimum inhibitory concentrations (MIC) and minimum fungicidal concentrations (MFC) were from 7.81 to 500 and from 15.62 to 1000μg/mL respectively. The highest mean zone of inhibition (26.5mm), the lowest MIC value (7.81μg/ml) and the lowest MFC (15.62μg/ml) were observed in ethyl acetate extract of A. aspera against T. rubrum. The standard antifungal drug ketoconazole (10μg/disc) was used as the positive control and mean zones of inhibition were from 23 to 29mm. Further separation of active principle from ethyl acetate extract of A. aspera is under progress.
