The proximate, functional properties, anti nutrients and amino acid composition of Celosia spicata leaves were investigated. The sample contained moisture content (8.16±0.01%), total ash (15.3±0.63%), crude protein (10.2±0.01%), crude fat (1.15±0.01%), crude fibre (12.3±0.02%) and carbohydrate (47.6±0.63%). The sample contained oil absorption capacity (303%), water absorption capacity (440%), emulsion capacity (56%), emulsion stability (29%) and foaming capacity (12.5%) while the least gelation concentration was 8%W/V. The water and oil absorption capacities were relatively good, and the in-vitro protein digestibility (IVPD) was 82.2%. Glutamic acid (12.8g/100g crude protein) and aspartic acid (8.96g/100g crude protein) were the most abundant amino acid while cysteine (0.40g/100g crude protein) was the least. The total essential amino acid of the sample was calculated to be 94.97g/100g crude protein which showed that the sample contained moderate quantity of essential amino acids. The sample contained tannin (97.42mg/100g), saponin (4.93mg/100g), alkaloid (0.36mg/100g), phytate (21.08mg/100g) and oxalate (16.53mg/100g) respectively. This study would provide information on the nutritional potentials of Celocia spicata leaves.
