Abstract: Two polysaccharides(LLP1 and LLP2) were isolated from Longya lilium water extract with DEAE-Sepharose Fast Flow column.They are identified as pure polysaccharide and glycoprotein by HPGPC,respectively.The monosaccharide composi-tions of LLP1 consist of Man,Glu and Ara,and its molecular weight is 11756 D.The monosaccharide compositions of LLP2 are Gal,Rha and Ara and its molecular weight is 1038773 D.

Key words: Longya lilium polysaccharide(LLP), purification, molecular weight, HPGPC
