Abstract

Elaeagnus angustifolia was analyzed for determination of metals, phytoconstituents, bactericidal, fungicidal and insecticidal effects and to explore its chemical and biological potential. The root, branches, leaves, stem bark and root bark parts of E. angustifolia were found to contain iron, lead, copper, cadmium, zinc, chromium, nickel and cobalt in different concentrations. Crude extract of Elaeagnus angustifolia (Ea.Cr) was tested positive for the presence of alkaloids, flavonoids, saponins and tannins. Ea.Cr and its fractions, n-hexane (Ea.Hex), ethyl acetate (Ea.EtAc) and aqueous (Ea.Aq) showed bactericidal activity against Escherichia coli and Staphylococcus aureus, while against Pseudomonas aeruginosa only Ea.Hex and Ea.EtAc were effective. When tested for antifungal effect, Ea.Cr exhibited fungicidal action against Aspergillus fumagatus, Ea.EtAc and Ea.Aq against Aspergillus flavis and Ea.EtAc against Aspergillus niger. Ea.Hex was active against all three fungal strains. The chloroform fraction (Ea.CHCl3) was found inactive against the used microbes. Ea.Cr, Ea.Hex, Ea.CHCl3, Ea.EtAc and Ea.Aq caused mortality of Tribolium castaneum and Ephestia cautella insects observed after 24 and 48 h of treatment. These data indicate that E. angustifolia exhibits different heavy metals and compound groups. Methanolic extract of E. angustifolia and its various fractions possess antibacterial, antifungal and insecticidal activities, which elucidate medicinal application of the plant.
