title: An anti-inflammatory and immunomodulatory polysaccharide from Orbignya phalerata.
abstract: A polysaccharide, a glucan with mean M(r) of 1.0 x 10(6) (MP1), was isolated from the mesocarp of fruits of Orbignya phalerata. Chemical and spectroscopic studies indicated that MP1 has a highly branched glucan type structure composed of alpha-(1-->4) linked D-glucopyranose residues with (3-->4), (4-->6), and with (3-->6) branching points. MP1 enhanced phagocytosis in vivo and exhibited anti-inflammatory activity.
