Depigmentation and Characterization of Fucoidan from Brown Seaweed Sargassum binderi Sonder

[摘要] Fucoidan has many uses in the field of pharmacology, therefore it is necessary to improve the quality of fucoidan by increasing its purity. The objective of this study was to remove brown pigment from seaweed and observe the effect of the result to the activity of isolated fucoidan. In this study, the pigment was removed by organic solvents in the maceration step. The pigment removal using ethanol was found to give a better result than that of the solvent mixture (methanol: chloroform: water) from previous study, indicated by the appearance of fucoidan color. The result showed fucoidan has a better color, total carbohydrate was 89.23% and total sulphate 18.74%.
