Abstract
The antimicrobial activity of the Epilobium angustifolium, E. hirsutum, E. palustre, E. tetragonum and E. rosmarinifolium
ethanolic extracts was studied in vitro on Gram-positive and Gram-negative bacteria, yeasts and fungi. The cytotoxicity of theextracts was also evaluated using the Artemia salina test. All the extracts showed antimicrobial activity in a range ofconcentrations between 10 and 650 mg/ml of dry extract. E. angustifolium and E. rosmarinifolium had the most broad spectrumof action inhibiting bacteria, yeasts and fungi. The extracts were devoid of toxicity on Artemia salina within the range ofantimicrobial concentrations, suggesting that the action is selective on microorganisms. 2001 E
