Amino Acid Composition of Five Wild Edible Fruits of Assam, North-East India

Abstract

In this study, amino acids profiles of 5 wild edible fruits viz. Grewia sapida, Ottelia alismoides, Aporosa dioica, Antidesma bunius and Eugenia operculata found in Assam of North-East India were investigated by RP-HPLC equipped with C18 column. A total of 17 amino acids in varying compositions were identified and 8 of these are essential amino acids and 9 of these are non-essential amino acids. In all of the 5 wild fruits, 6 different amino acids were identified and these were aspartic acid (1.151-3.837 %), glutamic acid (2.283-9.667 %), arginine (0.904-7.187 %), valine (0.142-1.029 %), leucine (1.849-19.665 %), and histidine (0.467-12.986 %). A. bunius fruit showed the highest non-essential amino acid content whereas O. alismoides fruit displayed the highest essential amino acid content. Leucine was found to be the most abundant essential amino acid whereas glutamic acid was detected to be the most abundant non-essential amino acid.

“…48 Examining wild fruits in Assam revealed a high content of aspartic acid, arginine, glutamic acid, histidine, valine, and leucine, aligning with our findings. 49 Studies indicate that phenylalanine, tryptophan, and tyrosine are three essential components in plant metabolism that act as precursors of production of aromatic secondary metabolites such as lignin, anthocyanins, flavonoids, and alkaloids. The amount of aromatic amino acids has significant influences on the production of phenolic compounds.…”
