Anotace: The green techniques are plying a major role in the synthesis of nanoparticles and in this present study we used the herbal plant Cassia alata for the green synthesis of zinc oxide nanoparticles. This reducing agent generates zinc oxide nanoparticles (ZnO NPs) from zinc acetate solution within 15 minutes. The synthesized ZnO NPs was characterized by UV-vis spectrophotometer shows surface Plasmon resonance band at 335 nm. Scanning electron microscope (SEM) image showed the size of the crystalline nanoparticles ranging from 30- 50 nm. Energy dispersive X-ray analysis (EDAX) confirms the presence of elemental Zn and O in the synthesized nanoparticles. FTIR revealed that presence of functional molecules like carboxylic acids, amine ant nitro groups associated with synthesized oxide nanoparticles. Atomic force microscope (AFM) shows spherical shape of nanoparticles as well as aggregation also observed. Thus green synthesized nanoparticles were tested for their antidermatophytic potential against Trichophyton mentagrophyte, Trichophyton rubrum, Epidermophyton floccosum, Microsporum audouinii, and Microsporum canis and recorded percentage of inhibition, MIC and MFC values.
