Isolation, Structural Characterization, and Biological Activity of the Two Acidic Polysaccharides from the Fruits of the Linnaeus.

Linnaeus is a medicinal plant and its fruit has pharmacological activity such as antiinflammatory, antiedema, antinociceptive, and muscle relaxant functions, etc. Two acidic homogeneous polysaccharides (EAP-H-a1 and EAP-H-a2) were isolated from the fruits of L. through DEAE-52 and Sephadex G-75 column chromatography, and the physicochemical, structural properties, and biological activities of the polysaccharides were investigated.

Structural characterization and antioxidant activities of a water soluble polysaccharide isolated from Glycyrrhiza glabra.

A water-soluble polysaccharide, named GPN, with molecular mass 38.7 kDa was isolated from Glycyrrhiza glabra with hot water extraction, ethanol precipitation, and purified by column chromatography. Monosaccharide composition analysis confirmed the presence of predominant glucose (98.
