Eichhornia crassipes, is a floating plant, an invasive plant in much of the world where it often jams rivers and lakes with tons of floating plant matter. E. crassipes form mats that clog waterways making fishing impossible and reduces water flow. Water-hyacinth is a rich source of many phytochemicals. In this study, various extracts of water hyacinth have been made using solvents like distilled water, methanol, ethanol and diethyl ether of both shoot and root of the plant and its extraction yield was calculated. The highest yield was found in an extract prepared from the shoot in distilled water. Phytochemical analysis of the fractionates showed the presence of alkaloids, phenols, tannins, saponins, and quinones. The extracts also showed anti-microbial activity against potential human pathogens like Escherichia coli, Salmonella, Listeria, Pseudomonas and Staphylococcus.
