Abstract: Two polysaccharides are isolated from lily.The polysaccharides (LP1、LP2) are separated after water abstract lily-polysaccharide was eluted from DEAE-cellulose column,and make up 0.55 and 0.25 percent of fresh lily weight respectively.LP1 and LP2 are pure polysaccharides by appraised of purity.The chemical components and the molecule weight of the two polysaccharides are appraised by gas chromatography and chromatography on Sephadex G-200 column,respectively;resultes are:LP1’s sugar composition comprises:Glu.、Man.With a rate of 1:2.46, and its molecule weight is 79400.LP2’s sugar composition comprises: Glu.、Gal.、Man.、Ara.and Gal.Acid with a rate of 1:0.73:2.6:1.8:0.84,and its molecular weight is 18150.
