A comparative study was carried out on chemical and amino acid composition of six Nigerian under-utilized legume (two varieties of bambara groundnut, kersting`s groundnut, two varieties of rear cowpea and cranberry beans) flours. The crude protein values ranged from 7.5g/100g in moderate brown coat cowpea to 51.5g/100g in cranberry beans. The ether extract, crude fibre, ash, moisture and carbohydrate value ranged form 3.1 – 6.9, 2.4 – 4.4, 3.2 – 4.6, 0.4 – 3.0 and 31.5 – 82.9g/100g respectively. All the studied legume flours were found to be good sources of essential minerals such as K, Mg, Ca, P, Na, Fe but Cu, Mn and Zn contents were low while Ni, Co, Pb, Cr and Hg were not detected. The amino acid analysis revealed that the legume were superior with respect to Arg, Leu and Phe when comparing the essential amino acids in the studied samples with the recommended FAO/WHO provisional pattern however supplementation may be required in Ile, Lys and Val.
