Dendrobium tosaense is a medicinal Dendrobium species widely used in traditional medicine. This study demonstrated some structural characterizations and immunomodulatory activity of the water-soluble polysaccharides derived from the stem of D. tosaense (DTP). DTP was fractioned using DEAE-650 M anion-exchange
