Characterization, antioxidant and anticoagulant properties of exopolysaccharide from marine microalgae

Abstract

Keypoints Sulfated exopolysaccharides (sPS) were extracted from marine green microalgae by the heated acid extraction method. sPS with the higher sulfate/sugar ratio presented potent ABTS radical scavenging activity. Some of the sPS revealed anticoagulant effects in activated partial thromboplastin time (aPTT) and prothrombin time (PT) assays.
