Abstrak/Abstract Brown marine algae are the prominent source of marine natural products having bioactive metabolites. Sargassum turbinarioides (ST) and Sargassum ilicifolium (SI) were dominated in Indonesia as brown marine algae that well known as a source of fucoidan. In this study, we investigated and identified the yield of aqueous crude and purified extracts using different extraction temperatures (60°C, 70°C, 80°C, 90°C). The highest yield of S. turbinarioides crude extract (7.36%) was obtained at temperatures 90°C and 80°C while the highest return of S. ilicifolium was 3.49% at 80°C. Each of the extracts was screened using Thin Layer Chromatography (TLC), Fourier transforms infrared spectroscopy (FTIR) analysis and Nuclear Magnetic Resonance (NMR) spectroscopy. The FTIR spectrum of the S. turbinarioides (ST) and S. ilicifolium (SI) extract refer to the presence of ester sulfate groups through showing peaks at 1300 to 1200 cm -1 and 980 to 950 cm -1 . The NMR analysis proposed that the main structure of extract is L-fucopyranose and presence of different type of fucose sulfate groups. The result indicated that S. turbinarioides (ST) and S ilicifolium (SI) contained sulfate polysaccharide. This may be a potential basic for development of marine nutraceuticals.
