Marine Drugs, Journal Year: 2025, Volume and Issue: 23(3), P. 98 - 98

Published: Feb. 23, 2025

Sargassum fusiforme polysaccharides (SFPs) are acidic that possess significant medicinal and commercial potential. This review aims to summarize recent advances in the structure, extraction methods, diverse biological activities of SFPs, including their antioxidant, antitumor, immunomodulatory, antiviral, intestinal flora-regulating, anti-diabetic properties. The key findings reveal complex composition polysaccharides, highlighting alginic acid, fucoidan, laminaran as primary constituents, detailing structural features. At same time, characteristics well advantages disadvantages hot water extraction, acid alkali ultrasonic microwave enzyme were systematically compared. Finally, this concludes by emphasizing necessity for further research elucidate structure–function relationships optimize techniques, provide a theoretical foundation subsequent studies.

Free and bound phenolic profiles and antioxidant ability of eleven marine macroalgae from the South China Sea

Frontiers in Nutrition, Journal Year: 2024, Volume and Issue: 11

Published: Oct. 14, 2024

Marine macroalgae are of broad interest because their abundant bioactive phenolic compounds. However, only a few previous studies have focused on bound In this study, there were significant differences in total content, phlorotannin flavonoid and antioxidant ability free forms, as well bound-to-free ratios, among 11 marine macroalgal species from the South China Sea. Padina gymnospora had highest content fractions, activity fractions. Sargassum thunbergii whereas oligocystum Moreover, 15 acids, 35 flavonoids, 2 stilbenes, 3 bromophenols, phlorotannins characterized quantified using ultra-high-performance liquid chromatography with Xevo triple quadrupole mass spectrometry, 42 compounds reported fractions seaweeds for first time. Among species, number amount varied greatly main components different. largest number, while Turbinaria ornata showed amount. Coutaric acid diosmetin dominant polycystum , hinokiflavone was Caulerpa lentillifera cyanidin other seaweeds. Hierarchical cluster analysis used to divide seaweed into seven groups. This study revealed that promising functional food resources.
