Extraction, Enrichment, Characterization, and Antioxidant Activities of Sargassum fusiforme Polyphenols

This study investigated the extraction, enrichment, characterization, and antioxidant activi- ties of Sargassum fusiforme polyphenols (SFPs). The optimal extraction process conditions of SFPs are as follows: an ethanol volume fraction of 28%, a liquid–solid ratio of 29 mL/g, an extraction temperature of 80 ◦C, and an extraction time of 3.2 h. After enrichment by D101 macroporous resin, the purity of SFPs increased from 1.20 ± 0.08% to 10.78 ± 0.25%, increas- ing by approximately 8 times. SFPs...
