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.

Coastal waters of Indonesia have considerable biodiversity of sea cucumbers. In the present study the amino acid and fatty acid contents in sea cucumber Stichopus vastus collected from Salemo Island waters Indonesia were determined. Results showed that all essential and non-essential amino acids were found in S. vastus. The major essential amino acid content was arginine (28651.62 mg/Kg). Whereas the major non-essential amino acid content was glycine (60907.24 mg/Kg). The total fatty acids were determined in which finding suggested that saturated fatty acid was more than polyunsaturated fatty acid and monounsaturated fatty acid. The higher saturated fatty acid, polyunsaturated fatty acid and monounsaturated fatty acid were palmitic acid (0.07%), arachidonic acid (0.13%) and palmitoleic acid (0.03%) respectively.

Mudskipper or glodok fish is a unique fish that can crawl and climb mangrove roots with their fins. In Indonesia, this fish is exported to abroad as a source of food. The by-product of this fish is rarely used, which one is their mucus. Protein is a composition of fish mucus which consists of  amino acids. The mucus of fish has the potential as a source of medicine because it’s proven to have antibacterial, antiviral, and antifungal activities. This study aims to determine the protein and amino acid content of fresh meat and mucus extract of mudskipper. Protein content testing was carried out using the titrimetric method, while amino acid content using the UPLC method. In this study, mucus extract has protein content at 1.79%. It’s small than the protein content of fresh meat at 17.7%. The highest essential amino acid in fresh meat and mucus extract of mudskipper was leucine (15% and 0.91%). The highest nonessential amino acid in fresh meat and mucus extract of mudskipper were glutamic acid (26.4% and 1.6%). The limiting amino acid in fresh meat is leucine as 226.9% and lysine as 12.27% in the mucus extract of mudskipper.
