This study aimed to use an existing ligand (imidazole)-assisted 1H-nuclear magnetic resonance (1H-NMR) spectroscopy protocol determine sulfate content of seaweed sulfated saccharides. Twenty samples – spanning nine species and multiple geographic locations were analyzed. Extracts obtained by immersing freeze-dried seaweeds in boiling water, followed alginate precipitation. Remaining supernatant...

Sulfated glycoproteins extracted for the first time from Moroccan green seaweed Codium decorticatum were investigated their ability to induce a natural defense metabolism in roots and upper leaves of tomato seedlings. The crude (AGB) purified fractions (AGP) characterized chemically (Colorimetric assays) structurally (SEC-MALS, GC-EI/MS, ATR-FTIR). elicitor aqueous solutions (1 g/L) applied by ...

The most prevalent natural source of hydrocolloids, cosmetics, medications, and nutraceuticals is marine seaweed (macroalgae). Numerous bioactivities, including antiviral, anticancer, anti-inflammatory, immunomodulatory characteristics, have been found in bioactive substances such as polyphenols sulfated non-sulfated polysaccharides. As a result, new start-up projects industries based on are em...
