摘要
A neutral polysaccharide Gi-A1 was isolated from the roots of Glycyrrhiza inflata Bat. It had a molecular mass of over 2000 kDa and showed [alpha] (D) (20) 81.4A degrees (c 1.05, H2O). Acid hydrolysis and methylation analysis indicated that Gi-A1 was mainly composed of alpha-D-glucose, alpha-L-arabinose, and alpha-D-galactose with a molar ratio of 8.0:1.8:1.0. It can significantly stimulate spleen cell proliferation in vitro (P < 0.01).
