Objectives: High level of morbidity and mortality due to the influenza virus is an emerging public health concern. Because there are few approaches to control and treat this infection, plant extracts including pomegranate extract can be a treatment of choice. So, the present study was conducted to investigate the mechanism of action of PPE against influenza virus A/Puerto Rico/8/34 (H1N1; PR8) in MDCK cells.

Materials and Methods: In this research, a crude ethyl alcohol extract of pomegranate peel was prepared, and the action mechanism of PPE in inhibiting influenza replication was studied by time of addition assays, virucidal activity, RNA replication, hemagglutination inhibition assay, viral mRNA expression, and western blot analysis.

Results: Results showed that PPE inhibited viral polymerase activity, viral RNA replication, and viral protein expression but failed to influence hemagglutination inhibition and virucidal activity. According to the time of addition assay, PPE inhibited the virus adsorption and early step of influenza replication.

Conclusion: This study demonstrated that in vitro antiviral effect of PPE on the influenza virus is very likely to be associated with inhibition of viral adsorption and viral RNA transcription.

Keywords: Antiviral activity, Influenza virus, pomegranate, Punica granatum L.
