Molecular characterization and biological activities of watersoluble sulfated polysaccharides from Enteromorpha prolifera

Lactic acid production from seaweed hydrolysate of Enteromorpha prolifera (Chlorophyta)

“…The content of crude polysaccharide was calculated to be 1.23 g on the basis of 10 g seaweed and included L-rhamnose (0.75 g), D-glucose (0.28 g), D-xylose (0.04 g), and uronic acid (0.16 g). The sugar yield of E. prolifera hydrolysate shown in the present work (23.4%) was almost two fold higher than that (12.3%) of E. prolifera polysaccharide reported by Cho et al (2010). As a result, it is thought that acid hydrolysis is more efficient than ethanol extraction in terms of sugar recovery.…”

“…Filled circles, L-rhamnose; empty triangles, D-xylose; filled triangles, D-glucose; empty circles, D-glucuronic acid solution (pH >9), D-glucuronic acid lactone could be converted to D-glucuronic acid. The data obtained in this work were compared with the study of Cho et al (2010) to examine the efficiency of acid hydrolysis in monosaccharide production. According to Cho et al (2010), the polysaccharide was produced by ethanol extraction.…”

Anti-inflammatory activity of a sulfated polysaccharide from the brown alga Sargassum cristaefolium

“…Several reports have demonstrated a correlation between biological activities and the Mws of polysaccharides isolated from S. pallidum, Enteromorpha prolifera, and Porphyridium cruentum (Cho, Yang, Kim, & You, 2010;Sun, Wang, Shi, & Ma, 2009;Ye et al, 2008). In this study, the original SCP extract contained three polysaccharides with average Mws of 1193.2, 864.4, and 386.1 kDa, as analyzed by Sephacryl S-400HR gel permeation chromatography.…”

The First Record of Biological Activities of the Egyptian Red Algal Species Compsopogon helwanii

“…It may share also, in the antioxidant activity of red alga C. helwanii extract. While [26] focused on the fact that seaweeds and freshwater algae may contain other antioxidative substances as tocopherols, chlorophylls, flavonoids and carotenoids which get partitioned into organic solvents and impart the radical scavenging activity to the extracts from these organisms.…”
