ABSTRACT

The aim of this study is to exam ine the phytochemical screening, ch emical composition and antimicrobial activities of ethanol extracts of both the leaves and stems of  Cymbopogon citratus.  For proximate analysis,  results for the leaves on the Moisture content, ash content, fat content, crude fibre, crude protein and carbohydrate were: 13.50, 11.17, 10.00, 19.54, 17.50 and 28.29% while that of the stem were: 7.98, 14.29, 13.50, 12.5, 17.50 and 34.23%, respectively. Also, the extracts was screened against two gram-negative bacteria,  Klebsiella pneumoniae and  Proteus vulgaris, two gram-positive bacteria,  Bacillus subtilis and Staphylococcus aureus and  fungi strain Penicillium  and mucor  at three different concentrations [1:1, 1:2 and 1:3] using Disc diffusion method. For both the leaves and stem extracts, the phytochemical analysis revealed the present of tannins, flavonoid, phlobotannins and cardiac glycosides but absence of alkaloid and saponin.
