The potential of antifungal effects of Walnu t (Juglans regia L., Juglandaceae) ethanolic and chloroform extracts was reported against four pathogenic fungi: three dermatophytes, Microsporum canis (MC), Trichophyton mentagrophytes (TM) and T. Ru brum (TR), and the causative agent of chalk brood disease of bees, Ascophaera apis (AsA). Both extracts had considerable activity against the studied fungi. The main antifungal component of walnut was isolated and tested for its antimycotic activity individually. Based on its IR, 13C and1H NMR analysis the main significant activity against was indentifying to be 5-hydroxy- 1, 4- naphthoquinone (Juglone).
