Chemical Composition and Antifungal Activity of Nectaroscordum tripedale Extract Against Some Pathogenic Dermatophyte Strains

This investigation aims to assess the chemical composition and antidermatophytic properties of Nectaroscordum tripedale against some pathogenic dermatophyte strains. In vitro antidermatophytic effects of N. tripedale extract on Trichophyton mentagrophytes, Microsporum canis, and Microsporum gypseum was determined using the determination of minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) based on the broth microdilution method, according to the protocol M38-A2 of the Clinical and Laboratory Standards Institute (CLSI) for filamentous fungi with some modifications. The components of the N. tripedale extract were identified by gas chromatography/mass spectroscopy (GC/MS) analysis. The results demonstrated that N. tripedale extract had both fungistatic and fungicidal activities with the MIC and MFC ranging from 16.6 to 66 mg/ml. The main compounds are decadienal (11.1%), hexadecanoic acid (10.3%), and heptadecane (9.5%), respectively. Obtained results of this investigation recommend a first step in the search of new antidermatophytic agent and support the use of N. tripedale in the folk medicine for dermatophytic infections.
