This research evaluated in vitro and in vivo antiviral effects of Peganum harmala L. seeds (PHS) extract against influenza A virus. Materials and Methods: In this research, in vitro anti-influenza A virus activity of the extract was assessed in Madin-Darby canine kidney (MDCK) cells. In order to evaluate anti-influenza activity of PHS extract in vivo, BALB/c mice were infected with 5LD50 of mouse-adapted influenza virus (H1N1; PR8) and received 200 mg/kg/day of PHS extract or 20 mg/kg/day oseltamivir. Lungs of seven mice per group were removed on day 3 post-infection and lung virus titers were determined by qRT-PCR. Mice survival, body weights and general conditions were observed for up to 14 days post-infection. Results: The results demonstrated that, the ethanolic extract of PHS possesses high activity against influenza virus with IC50 value of 15.7 (CI95%:11.7-21) μg/ml in MDCK cells. Our results also showed that, oral administration of PHS extract (200 mg/kg/day) or oseltamivir (20 mg/kg/day) to infected mice, increased the survival rate, reduced body weight loss, and decreased lung virus titer. Conclusion: Based on our findings, P. harmala seeds extract can inhibit influenza A virus replication in vitro and in vivo. Therefore, isolation and characterization of the plant’s active compounds and investigation of the underlying mechanisms of its antiviral action are highly suggested.
