抜粋

The structural features of ukonan C, the polysaccharide having remarkable reticuloendothelial system-potentiating activity obtained from the rhizome of Curcuma longa L., were investigated by methylation analysis, carbon-13 nuclear magnetic resonance, periodate oxidation and enzymic degradation studies. It is mainly made up of arabino-3,6-galactan type and 4,6-branched glucan type structural units. Degradation with a-amylase followed by the elimination of 1,4-linked glucan side chains resulted in a marked decrease of its immunological activity.
