2142270 9404162 PCTABS00030 Polysaccharides from the gum exudates of Astragalus species Tragacantha section plants are extracted, separated and modified into water-soluble forms free of small molecular impurities. The purified polysaccharide forms are immunomodulators which inhibit cancer cells and viruses, and can be used to treat immunologically defective disease states. The polysaccharide-homogeneous products from different Astragalus species exhibit the same kind of immunomodulatory activity in different mammalian systems, but differ in potency. The purified polysaccharide forms of these GRAS gum tragacanth products show no toxicity on parenteral administration.
