Abstract

Phytochemical analysis and antimicrobial activities of the aqueous ethanolic extract of Saccharum officinarum were carried out. The antimicrobial activity was screened by disc diffusion method while the analysis of the different phytochemicals was carried out using standard methods. The result showed that the extract had inhibitory effects on the gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa). The effect of the extract was minimal on Staphylococcus aureus, a gram positive bacteria suggesting some degree of resistance by the organism. The result of the phytochemical screening showed that extract contains saponins, tannins, flavonoids and reducing sugars. The findings show that the plant bark extract has bactericidal activity and could be used in the control and treatment of bacterial infection especially the gram negative bacteria.
