Proximate Analysis, Mineral Contents and Amino Acid Composition of Antrocaryon micraster Stem Bark

In the present study, the proximate, mineral and amino acid composition of the stem bark of Antrocaryon micraster was determined. Results of the proximate analysis revealed the presence of 12.4 ± 0.0 % moisture; 9.01 ± 0.01 % ash; 13.8 ± 0.1 % crude protein; 1.20 ± 0.04 % fat and 51.9 ± 0.1 % carbohydrate. The mineral composition showed high level of K (889 ± 1.0 mg/100g), Ca (628 ± 3.0 mg/100g), P (104 ± 1.0 mg/100g) and low levels of Mn (6.71 ± 0.03 mg/100g), Zn (5.29 ± 0.10 mg/100g) and Cr (0.1 ± 0.0 mg/100g). The antinutrients studied revealed lower range of values when compared with most vegetables. Two acidic amino acids (glutamic and aspartic acid) were the highest concentrated amino acids (15.2 ± 0.0 and 10.0 ± 0.1 g/100g crude protein). The total amino acid was 81.6 g/100g crude protein, while the total essential and non-essential amino acids were 36.4 and 45.2 g/100g crude protein respectively. The predicted protein efficiency ratio (P-PER) of Antrocaryon micraster stem bark was 1.55 and the calculated isoelectric point (pI) was 4.67.
