The aim of this study is to examine the phytochemical screening, chemical 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.
