Abstract

The present study aims to examine the phytochemical and antibacterial potential of different solvent extracts of leaf of Eugenia floccosa. The preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, glycosides, terpenoids, steroids, saponins, phenols, tannins, coumarins, catechin and sugars in the methanol and ethanol extracts of leaf of E. floccosa. The FT-IR spectrum confirmed the presence of C=O, C-H, C=C, C-O and C=C. The antibacterial activity has been observed in the petroleum ether, methanol and ethanol extracts of leaf of E. floccosa against the tested bacteria with wide-ranging activity. The methanol extract of leaf of E. floccosa showed highest zone of inhibition against Escherichia coli (16 mm). It is hoped that, this study would direct to the establishment of some compounds that could be used to formulate new and more effective antibacterial drugs of natural origin.
