Preliminary phytochemical, FT- IR and antibacterial assessment of leaf of Eugenia singampattiana Bedd (Myrtaceae)

The present study is to investigate the phytochemical and antibacterial activity of different solvent extracts of leaf of Eugenia singampattiana. The preliminary phytochemical screening revealed that alkaloids, flavonoids, glycosides, terpenoids, steroids, saponins, phenols, tannins, coumarins, catechin and sugars were found to be present in the methanol and ethanol extracts of leaf of E. singampattiana. The FT-IR spectrum confirmed the presence of C=O, C-H, C=C, C-O and C=C groups. The antibacterial activity has been observed in the petroleum ether, methanol and ethanol extracts of leaf of E. singampattiana against the tested bacteria with varied activity. The methanol extract of leaf of E. singampattiana showed maximum zone of inhibition against Staphylococcus aureus (20 mm). It is hoped that, this study would direct to the establishment of some compounds that could be used to invent new and more potent antibacterial drugs of natural origin.
