Polysaccharides From Dendrobium Officinal, Cordyceps Sinensis and Ganoderma: Structures and Bioactivities

In the past decades, polysaccharides isolated from natural sources (herbs) have attracted much attention due to their various types of bioactivities. A variety of polysaccharides extracted from botanical plants and fungi have been reported for their bioactivities, with claimed health benefits including immune regulation, anti-tumour and antioxidant activity. The paper focuses on polysaccharides isolated from three sources: Dendrobium officinal, Cordyceps sinensis and Ganoderma. The structural information, bioactive properties as well as their structural & function relationships are discussed.
