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.
