Abstract: Proximate composition, Amino acids profile, mineral content and antinutritional factors of tender leaves of Amaranthus viridis were evaluated using standard methods of analyses. The leaves had the following proximate compositions on dry weight (DW) basis: ash (21.05%), crude protein (35.11 ± 0.33%), crude lipid (5.26 ± 0.30%), crude fibre (14.04 ± 0.35%), available carbohydrate (24.54 ± 0.71%) and calorific value (530.34 ± 0.01 kcal/100g).  The amino acids profile indicates that the leaves are good source of essential amino acids for adults. The leaves are rich in K, Mg, Fe, Mn and Cu when compared to their respective RDA values. Tannins (7,530.21 ± 5.21 mg/100gDW) and phytate (1,326.92 ± 16.57 mg/100gDW) were the plant’s predominant antinutrients while total oxalate (202.50 ± 6.50 mg/100gDW) and soluble oxalate (97.50 ± 3.75 mg/100gDW) were in appreciable concentration. The amounts of hydrogen cyanide (13.07 ± 2.38 mg/100gDW) and nitrate (25.35 ± 2.74 mg/100gDW) were below the critical values. The results are an indication that the Amaranthus viridis leaves had the potential to be used as source of nutrients in alleviating macro- and micro- nutrient deficiencies.
