The antimicrobial activities of methanol extracts of seven Verbascum species were studied. The dried extracts of the aerial parts of Verbascum dudleyanum (Hub.-Mor.) Hub.-Mor., V. latisepalum Hub.-Mor., V. mucronatum Lam., V. olympicum Boiss., V. stachydifolium Boiss. & Heldr. and V. uschackense (Murb.) Hub.-Mor., the flowers of V. lasianthum Boiss. were tested against standard bacterial strains of Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212), and standard fungal strains of Candida albicans ATCC 90028, Candida parapsilosis ATCC 90018 and Candida krusei ATCC 6258 by disc diffusion methods, which were recommended by Clinical and Laboratory Standards Institute. While V. mucronatum Lam. and V. olympicum Boiss. showed an antibacterial activity against gram positive bacteria, and S. aureus as well as V. latisepalum Hub.-Mor. showed an antifungal activity against C. krusei. The other species had no activity.
