Effects of solvent extraction and drying methods of Malaysian seaweed, Sargassum polycystum on fucoxanthin content

This study aims to evaluate the effects of solvents extraction and drying methods on selected fucoxanthin content in Sargassum polycystum that was collected from Blue Lagoon, Port Dickson Malaysia. Two different were used this study, i.e sun-drying air-drying. Acetone, methanol ethanol as extract S. polycystum. The results showed both had a statistically significant effect (p < 0.05) Among three with two investigated, acetone air-dried sample gave highest (0.282 ± 0.08 mg/g DW) followed by ethanolic (0.198 0.13 DW). Sun-drying extracted yielded lowest amount (0.028 0.02 Concisely, best method is air-drying solvent.
