摘要： Three polysaccharides, TAA, TAB, TAChave been isolated from the pollen of Typha angustifolia L., and purified by hot water extraction, alcohol precipitation, Sevage method, gel filtration (Sephadex G50) and ion-exchange chromatography on DEAE Sephadex A25 and DEAE-cellulose. Their purities were tested by gel filtration and electrophoresis. Their structures were characterized by paper chromatography of the hydrolysis products, GLCanalysis of the alditol acetates, alkylation analysis, 1H NMRand 13C NMRspectra. TAAis mainly composed of a-L-arabinofuanose, β-D-galactose and α-D-galacturonic acid, while the backbones of TABand TACare composed of (1→5)-linked α- L-arabinofuranosyl residues.
