The study evaluated the chemical composition of Alternantherabrasiliana leaves and Hibiscus sabdariffa calyces used in improving the iron and zinc contents of maize-bambara groundnut and maize-cowpea complementary foods. A. brasiliana leaves and H. sabdariffa calyces were freshly harvested, dried at 50oC for 48 hour and analyzed for the relevant chemical components. Alternantherabrasiliana leaves and Hibiscus sabdariffa calyces contains 8.04 and 7.66%  protein; 0.45 % and 0.35 % crude fat; 13.68 and 12.12 % crude fibre;8.65 and 6.25 % ash content; 4.68g/kg and 5.70 g/kgcalcium; 0.19 and 0.35 g/kg iron; 0.02 and 0.07 g/kg zinc respectively. The essential amino acids in Alternantherabrasiliana and Hibiscus sabdariffa were isoleucine (20.35 and 21.20 mg/kg); lysine (20.35 and 21.20 mg/kg); valine (41.85 and 41.90 mg/kg) histidine (20.55 and 20.33 mg/kg) and phenylalanine (51.65 and 50.55 mg/kg) respectively. The unsaturated fatty acid, oleic acid occurred at 152.7 and 154.7 mg/kg level, linoleic acid (217.7 mg/kg and 220.9 mg/kg) and linolenic acid (124.3 mg/kg and 122.7 mg/kg) for A. brasiliana and H. sabdariffacalyce respectively. The anti-nutrients content of Alternantherabrasiliana and Hibiscus sabdariffawere oxalate (101.30 and 51.25 mg/kg); phytate (88.55 and 75.85 mg/kg); tannin (52.5 mg/kg and 48.6 mg/kg).

Key words: Alternantherabrasiliana leaves, Hibiscus sabdariffa calyces, nutritional composition, amino acid, fatty acid, anti-nutrients, maize-bambara groundnut, maize-cowpea.
