Extraction And Characterization Of Fucoidan From Six Brown Macroalgae, Chun-Ying Wang, Yean-Chang Chen
Journal of Marine Science and Technology
The content and composition of fucoidan in six brown macroalgae were investigated. The influence of different washing steps and two types of extraction methods on the yield and composition of fucoidan were assessed. The composition of the extract was determined by using a colorimetric method to measure the total sugar, sulfate, and protein contents of the fucoidan. The monosaccharide composition was assessed using high-performance liquid chromatography. The structures of the algal polysaccharide were studied using Fourier transform infrared-attenuated total reflectance spectroscopy. The fucoidan content extracted using method I was 13.13% (of dry weight), 24.00%, and 22.67% from Sargassum glaucescens, Sargassum …
