Biological screening of Elaeagnus umbellata Thunb

The bark and fruit extracts of Elaeagnus umbellata have been investigated for their antibacterial, anti-fungal, insecticidal and phytotoxic activities. The petroleum ether extracts of the plant showed significant activity against E. faecalis. The activity of dichloromethane extract was also determined significant against S. aureus. The chloroform extract indicated low activity against E. coli, K. pneumoniae, B. subtilis and S. flexenari. The ethyl acetate fraction demonstrated significant activity against K. pneumoniae while methanolic extract exhibited significant activity against E. coli. All extracts showed low phytotoxic activity. The dichloromethane extract exhibited moderate insecticidal activity while other extract indicated low activity.
