Abstract

One neutral polysaccharide PSPⅠ was isolated from Polygonatum sibiricum,by water extraction,eth-anol precipitation and purification through DEAE-cellulose,sephacryl-S400 and Sephadex G-100 column chromatogra-phy.The structure was investigated using sugar composition analysis and 1H-NMR,13C-NMR,135DEPT-NMR anal-ysis.The result showed that the main chain of PSPⅠ was ketose which linked by β-(1→2) bond,the glucose was linked to the main chain by α bond.

Key words： Polygonatum sibiricum Redoute; polysaccharide; structural determination
