Molecular Weight and Monosaccharide Composition of Polysaccharide from Lycoris aurea
摘要
Abstract
To Study the molecular weight and monosaccharide composition in polysaccharide from PBL1,PBL2 and PBL3.The molecular weight and monosaccharide composition in polysaccharide were determined by GPC-MALS-RI and HPLC.The results showed that the average molecular weight (Mw) of PBL1-1,PBL2 and PBL3 were 3.642 × 103,1.206 × 104 and 3.992 × 105 g/mol,respectively.PBL1-1 consisted of D-Man,D-Glu and D-Gal with the mole ratio of 1∶ 0.34∶ 0.036.PBL2 was composed of D-Man,Rha,D-Gal UA,D-Glu,D-Gal and Ara with the mole ratio of 1∶ 0.29∶0.78 ∶ 21.89∶ 2.69∶ 0.63.PBL3 was composed of D-Man,Rha,D-Glu UA,D-Gal UA,D-Glu,D-Gal and Ara with the mole ratio of 1∶2.63∶ 0.47∶ 1.63∶ 0.83∶ 6.92∶ 1.34.The polysaccharide of PBL1,PBL2 and PBL3 from Lycoris aurea consisted of D-Man,D-Glu and D-Gal,which had considerable differences in molecular weight.关键词
