Antioxidant activities of sulfated pumpkin polysaccharides

International Journal of Biological Macromolecules, 2019
Pumpkin polysaccharide was extracted by hot water extraction method. It was modified with chlorosulfonic acid-pyridine to obtain sulfated pumpkin polysaccharides (SP1, SP2) with different degrees of substitution, which was 0.35 and 0.65, respectively.

Anticoagulant properties of semisynthetic polysaccharide sulfates

Thrombosis Research, 1991
Several naturally occurring polysaccharides were purified and subsequently sulfated by chlorosulfonic acid-pyridine complex. These were isolated as the sodium salt and further purified by ECTEOLA cellulose chromatography. Anticoagulant properties of the sulfated polysaccharides were compared with commercial heparin by measuring their in vitro effects ...

Separation, purification, structural analysis and immune-enhancing activity of sulfated polysaccharide isolated from sea cucumber viscera.

International Journal of Biological Macromolecules, 2019
A novel sulfated polysaccharide (SCVP-1) was isolated from sea cucumber viscera and purified to elucidate its structure and immune-enhancing ability. SCVP-1 was found to be a homogeneous polysaccharide with a relative molecular weight of 180.8 kDa and ...

Anti-inflammatory action of sulfated polysaccharides

Biochemical Pharmacology, 1969
Abstract A number of sulfated polymers: pentosan polysulfate, polyvinyl sulfate, polyethylene sulfonate, cellulose sulfate, dextran sulfate, sulfate amylopectin, in the same way as carragenin, degraded carragenin and dextran, produce edema in the rat's paw by local injection, to release kinins from fresh guinea pig and rat's plasma (in vitro) and to ...

Sulfated polysaccharide as biomimetic biopolymers for tissue engineering scaffolds fabrication: Challenges and opportunities.

Carbohydrate Polymers
Sulfated polysaccharides play important roles in tissue engineering applications because of their high growth factor preservation ability and their native-like biological features. There are different sulfated polysaccharides based on different repeating

Sulfated Seaweed Polysaccharides as Antiviral Agents

Current Medicinal Chemistry, 2004
Several sulfated seaweed polysaccharides show high antiviral activity against enveloped viruses, including important human pathogens such as human immunodeficiency virus, herpes simplex virus, human cytomegalovirus, dengue virus and respiratory syncytial virus. They can be obtained in major amounts and at low costs, have low toxicity and in some cases,

A sulfated polysaccharide from Gracilaria Lemaneiformis regulates cholesterol and bile acid metabolism in high-fat diet mice.

Food & Function, 2019
This study aimed to evaluate the regulation of lipid metabolism and mechanism of a sulfated polysaccharide from Gracilaria Lemaneiformis (GLP). The results showed that GLP significantly decreased the hepatic total cholesterol (TC) and triglyceride (TG ...

sulfated polysaccharides from Durvillaea antarctica

Hydrobiologia, 1996
Durvillaea antarctica was extracted with hot water and a sulfate containing polymer was obtained after separation of laminaran and alginic acid with cetrimide and 2% calcium chloride solutions, respectively. Gel electrophoresis showed that the acidic polysaccharide (23.5% sulfate, 4.5% uronic acid) was not homogeneous.
