Effects of a polysaccharide extract from Amomum villosum Lour. on gastric mucosal injury and its potential underlying mechanism.

AVLP-2, a novel acidic polysaccharide, was isolated and purified from Amomum villosum Lour. The structural characteristics of the polysaccharides were characterized using monosaccharide composition, methylation, FT-IR, and NMR techniques. Results showed that AVLP-2 comprises galactose and glucose monomers, has a molecular weight of 10.
