Antimicrobial activity of Epilobium spp. extracts Lucia Battinelli, Beatrice Tita, Maria Grazia Evandri, Gabriela Mazzanti * Department of Pharmacology of Natural Substances and General Physiology, Uni6ersity ‘La Sapienza’, P.le Aldo Moro, 5, 00185 Rome, Italy Received 31 October 2000; accepted 10 January 2001 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 Keywords: Epilobium; Bacteria; Yeasts; Dermatophytes; Artemia salina 1.
