Comparative Study on the Amino Acid Profile of Eucheuma Cottonni and Gracilaria Sp. Seaweed

Jamaluddin Jamaluddin, Yuni Faradila Kum, Akhmad Khumaidi


Seaweed is a macro algae that lives in the sea having no roots, stems and leaves. Generally, seaweed contains carbohydrates (sugars or vegetable-gum), less fat, vitamins A, B1, B2, B6, B12, and C, beta-carotene and minerals, such as potassium, calcium, phosphorus, sodium, iron, iodine, protein, and amino acids. This study aimed to find out the amount of amino acids contained in Eucheumacottonii and Gracilariasp seaweeds and see if there are differences in amino acid levels in this samples taken from Silampayang Parigi Moutong District. Type of samples taken were Eucheumacottonii and Gracilariasp seaweed of approximately 5 meters from the beach. The analysis of amino acids used High Performance Liquid Chromatography (HPLC) and Ultra Performance Liquid Chromatography (UPLC).The test results showed that the Eucheumacottonii seaweed obtained 17 types of amino acids with the highest levels was from serine by 6.99 mg/g, while the lowest is tryptophan of 0.59 mg/g. Mean while,Gracilariasp obtained 16 amino acids types with the highest level was from glutamic acid of 2.46 mg/g and the lowest was from methionine of 0.39 mg/g. Both Eucheumacottonii and Gracilariasp seaweeds have significant differences of amino acids levels with P value <0.05.
