Agarans from the red seaweed Polysiphonia nigrescens (Rhodomelaceae, Ceramiales)

Polysiphonia nigrescens was sequentially extracted with water at room temperature, 70 and 90 °C. The extracts were analyzed and the major one, isolated at 70 °C, was fractionated by ion-exchange chromatography, eluting with water and solutions of increasing sodium chloride concentration; five main f...
