The study investigated the nutritional potentials of Eichhorniacrassipes, commonly known as water hyacinth. Proximate analysis showed that the leaf contained the highest percentage of crude protein (21.44+1.15%), followed by the stem (9.04±0.51%), with the least being in the root (6.86 ± 0.67%). The total carbohydrate was highest in the leaf (17.86±0.17%). The highest crude fibre content was observed in the stem (57.99±1.14%) while that of the root (24.47± 0.90%) was the lowest. All these values were significantly different (p<0.05) in the leaf, stem and root. The anti-nutrient composition showed that the leaf had the highest content of tannin (991.36±0.00mg/100g) and oxalate (9.63±0.00mg/100g) while the stem recorded the lowest values in tannin (706.01±0.00mg/100g) and oxalate (5.14±0.00mg/100g). In the vitamin profile, vitamin C was the most abundant, with its content being the highest in the stem (216.61±0.00mg/100g) and lowest in the leaf (204.80 ± 0.00). Vitamin D was the least, with its highest content in the root (6.28 x 10-6±0.00mg/100g) and lowest in the stem (3.63 x 106±0.00mg/100g). Amongst the essential amino acids, in the amino acid profile, leucine was found to be the highest in the leaf (7.02±0.00mg/100g), stem (8.08±0.00mg/100g) and root (8.69 ± 0.00mg/100g), while methionine was present in relatively lower levels. The non- essential amino acid profile had glutamine as the highest in content in the leaf (15.13±0.00mg/100g), stem (11.95±0.00mg/100g) and root (15.12±0.00mg/100g), while cysteine was the least for all. These results indicate the nutritional potentials of the leaf, stem and root of the Eichhorniacrassipes plant.
