The chemical compositions of the flour produced from the seeds of C. ensiformis and C. gladiata were determined using standard methods. The results obtained showed that, the percentage moisture contents of C. ensiformis (6.61 ± 0.19) was lower than that of C. gladiata (8.27 ± 0.29) seeds while the ash content C. ensiformis was higher (3.45 ±0.1) than C. gladiata (3.2 ± 0.05). Also, the result showed that C. gladiata has higher concentrations of dietary fibre (8.24 ± 0.24) than C. ensiformis (5.84 ± 0.37), and fat content of (2.05 ± 0.24) and (2.38 ± 0.61) respectively. The percentage crude protein of 25.89 ± 0.19 was obtained for C. ensiformis which is higher than 22.97 ± 0.39 of C. gladiata, C. ensiformis carbohydrate (56.17 ± 0.32) content was higher than that of C. gladiata (54.94 ± 0.90). The values of minerals showed that phosphorus was the most abundant mineral in both samples. However, the value obtained for C. gladiata (716 ± 10.41 mg/100g) almost doubled that of C. ensiformis (318 ± 2.12 mg/100g). Also, calcium (232 ± 2.83), potassium (32.31 ± 0.43), cupper (1.40 ± 0.14) and zinc (2.40 ± 0.28) were more concentrated in C. gladiata than C. ensiformis. The values for magnesium (11.98 ± 0.32), sodium (23.50 ± 0.49) and iron (5.69 ± 0.05) minerals were higher in C. ensiformis than that of C. gladiata. The amino acid results showed that C. gladiata had higher concentrations of total amino acids (87.51 g/100g protein), total non-essential amino acids (42.61 g/100g) and total sulphur amino acids (3.89 g/100g) than C. ensiformis. However, C. ensiformis had a better proportion of essential amino acids (46.31 g/100g). The research revealed that both C. gladiata and C. ensiformis could serve as a better source of dietary fibre, protein, carbohydrate, nutritionally valuable minerals as well as essential amino acids.
