Evaluation of diverse antioxidant activities in vitro of polysaccharides derived from brown algae

Among a large number of marine extracts and different isolated bioactive compounds, polysaccharides are recognized as one of the most promising sources of different biological activity, including anti-inflammatory, antioxidant, antimicrobial, antiviral, anti- coagulant, and antitumor activities thus paving the way for a new trend in the discovery of compounds from a sustainable source. This study aimed to conduct comprehensive research and determine antioxidant activities in vitro of water-soluble polysaccharide extracts from 5 brown algae (Fucus virsoides, Padina pavonica, Cystoseira barbata, Cystoseira compressa, and Halopteris scoparia), along with embryotoxicity potential to determine their safety for non-target organisms and humans. The highest extraction yields in acidic conditions after pretreatment with organic solvents for the removal of polyphenols and pigments were obtained for F. virsoides (18.21%) and C. compressa (14.81%). All samples had medium to high antioxidant activity, but the highest antioxidant activity was obtained for C. barbata and C. compressa extracts using DPPH, ABTS, and FRAP assays. The obtained results of embryotoxic testing have proven the safety of all isolated polysaccharide extracts, thus indicating the importance of marine-derived compounds in different areas of research and applications, from food supplements to higher pharmaceutical development.
