A glucan, called pinellian G, was isolated from the tuber of Pinellia ternata BREIT. It was homogenous on electrophoresis and gel chromatography, and its molecular mass was estimated to be 1.5 x 10(4). It is composed solely of D-glucose, in addition to a few O-acetyl groups. Methylation analysis, nuclear magnetic resonance and enzymic degradation studies indicated that it is a branched glucan mainly composed of α-1,4-linked D-glucopyranose residues with partially α-1,3-linked units and 4,6-branching points. The glucan showed significant reticuloendothelial system-potentiating activity in a carbon clearance test, as well as pronounced anti-complementary activity.
