ABSTRACT
Crude extracts of leaves and bark of E. jambolana were tested for antiviral activity against highly pathogenic avian influenza virus (H5N1) by CPE reduction assay in three different layouts to elucidate virucidal, post-exposure and pre-exposure antiviral activity of the extracts. The cold and hot aqueous extracts of bark and hot aqueous extract of leaves of E. jambolana showed significant virucidal activity (100% inhibition) which was further confirmed in virus yield reduction assay (~98 to 99% reduction) and by egg based in ovo assay. The selective index (CC50/EC50) of hot aqueous extract (248) and cold aqueous extract (43.5) of bark of E. jambolana showed their antiviral potential against H5N1 virus. The significant virucidal activity of leaves and bark of E. jambolana merits further investigation as it may provide alternative antiviral agent for managing avian influenza infections in poultry farms and potential avian-human transmission.
