ABSTRACT This study was designed to evaluate the antioxidant and cholinesterase inhibitory activities of sulfated polysaccharides from Gracilaria gracilis (PGCL) and Ulva lactuca (PULV). PGCL and PULV were extracted and characterized with Scanning electron microscope-energy dispersive x-ray (SEM-EDX), Fourier transform infrared spectroscopy (FTIR) and Gas chromatography-mass spectroscopy (GC-MS). The radical (2,2-azinobis-3-ethylbenzothiazoline-6-sulfonate [ABTS] 2,2-diphenyl-1- picrylhydrazyl… 

Influence of Gender and Age of Brown Seaweed (Fucus vesiculosus) on Biochemical Activities of Its Aqueous Extracts

Since this seaweed is often harvested in estuarine systems with high anthropogenic impacts, its safety was evaluated through the evaluation of the sample’s metal content, pointing to a safe food source.

Considerable Production of Ulvan from Ulva lactuca with Special Emphasis on Its Antimicrobial and Anti-fouling Properties

In the current study, a significant amount of ulvan was extracted from Ulva lactuca collected from Alexandria coastline, Egypt, using a simple extraction method. According to the chemical analysis,

Carboxymethylated Sulfated Heteroexopolysaccharide from a Haloarchaeal Strain as Potential Biomolecule for Harmless Adjuvant Therapy in Cancer Treatment

CS-hEPS are promising natural antioxidant, antifatigue, and antitumor harmless adjuvant materials that could be applied in human cancer therapy.

An Analysis of the Nutritional and Health Values of Caulerpa racemosa (Forsskål) and Ulva fasciata (Delile)—Two Chlorophyta Collected from the Philippines

Nutritional characteristics confirmed that C. racemosa could be potentially used as a nutritious and functional food items for human consumption and showed in vitro antiherpetic activity without cytotoxicity.

Production and Characterization of Exopolysaccharide From Newly Isolated Marine Probiotic Lactiplantibacillus plantarum EI6 With in vitro Wound Healing Activity

EI6-EPS was found to be safe (IC50 > 100 μg/ml) and induced human skin fibroblasts (HSF) proliferation and migration, implying that EI6 can be used as a safe source of bioactive polymer in wound care.

Sulfated Polysaccharides from Macroalgae—A Simple Roadmap for Chemical Characterization

The marine environment presents itself as a treasure chest, full of a vast diversity of organisms yet to be explored. Among these organisms, macroalgae stand out as a major source of natural products

The Protective Role of Sulfated Polysaccharides from Green Seaweed Udotea flabellum in Cells Exposed to Oxidative Damage

Treating the cells with the ultrafiltrate fractions (UF) fractions protected the cells from the oxidative damage caused by the two salts and ascorbate, suggesting that some of their protective mechanisms stem from these properties.

Isolation and chemical characterization of algal polysaccharides from the green seaweed Ulva clathrata (Roth) C. Agardh

FTIR spectra showed that soluble polysaccharides from the green seaweed U. clathrata are sulfated poly Saccharides, similar to ulvan obtained from other Ulva species and confirmed by the 1 H-NMR spectrum, where the characteristic signal for the deoxy sugar (rhamnose) is present.

Antibacterial activities of R-(+)-Limonene emulsion stabilized by Ulva fasciata polysaccharide for fruit preservation.

Inhibitory activities of Cystoseira crinita sulfated polysaccharide on key enzymes related to diabetes and hypertension: in vitro and animal study

It is demonstrated that the administration of CCSP to diabetic rats can make it a potentially strong candidate for industrial application as a pharmacological agent for the treatment of hyperglycemia, hyperlipidemia, and liver–kidney dysfunctions.

Evaluation of anticoagulant activity of two algal polysaccharides

Algal extracts showed to prolong the PT and APTT during the coagulation cascade and to avoid the blood coagulating of samples and this permits to consider the algae as the biological source of the future.
