Vigina sinensis, Anacardium occidentals, amino acids, "ulam".


A preliminary study was carried out on the amino acids content in the protein of two local plants which are normally eaten raw. They are Vigina sinensis and Anacardium occidentals. Reverse-phase HPLC method was used to separate the amino acid components which are released from the protein by hydrolysis. The amino acid mixtures were derivatised with ortho-phthaldehyde/2-mercaptoethanol (OPA/MCE) for detection in a fluorometric detector. The amount of amino acids content in Vigina sinensis and Anacardium occidenrale are 7.43 mg/g (dry edible portion) and 7.77 mg/g (dry edible portion), respectively. The presence of specific amino acids in the plants may enable them to be commercially utilized as a nutritious and cheap source of amino acid supplements.
