Phytochemical screening and in vitro antibacterial activity of Moringa oleifera (Lam.) leaf extract

Abstract

The study aimed to investigate the phytochemical constituents and antibacterial activity of ethanolic extract of Moringa oleifera Lam. belonging to family Moringaceae. Moringa oleifera is an interesting plant for its use in bioactive compounds. Ethanol and Distilled water were used as a solvent to extract and to detect the phytochemical constituent’s and to screen its antibacterial activity from the leaves of Moringa oleifera. The phytochemical constituents were screened by qualitative analysis method. The phytochemical screening finds out the presence of terpenoids, phenols, tannins, flavonoids, glycosides, etc. in leaf extract of Moringa oleifera. The antibacterial activity of ethanolic leaf extract of Moringa oleifera was examined against gram positive bacteria (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli). Antibacterial Activity were carried out with ethanolic extract of Moringa oleifera using agar well diffusion method. The present study showed that ethanolic extract of Moringa oleifera showed more potent antibacterial activity against S. Aureus and E. coli.
