Fifteen Argentine medicinal plants were tested for their antiviral activity in vitro against herpes simplex viruses types 1 and 2 (HSV-1 and 2), bovine viral diarrhoea virus type 1 (BVDV-1), influenza virus type A (Inf A) and human immunodeficiency virus type 1 (HIV-1). Antiviral activity was evaluated by a reduction in cytopathic effect, plaque-forming units and p24 HIV-1 antigen. The Selective Index of the active extract (SI(extract) = CC50(extract)/EC50(extract)) of Coronopus didymus (SI(extract) = 110.7), Juglans australis (SI(extract) = 8.1) and Lippia alba (SI(extract) = 19.2) against BVDV-1, HSV-1 and influenza A virus, respectively, justify a further analysis. None of the seven plants assayed against HIV-1 displayed any antiviral activity. The results of this study justify the continuing isolation and characterization of the antiviral components present.
