title: Chemical analysis of a polysaccharide from Cristaria plicata (Leach).
abstract: A polysaccharide (MPS) isolated from Cristaria plicata (Leach) consisted of d-glucose. Its structural characteristics were investigated by High Performance Liquid Chromatography (HPLC), infrared analysis, gas chromatography-MS, total acid hydrolysis, methylation analysis, periodate oxidation and Smith degradation. The results indicated that the polysaccharide of C. plicata (Leach) has the weight-average molecular weight of about 2.97 × 10⁶ Da. The structure of the polysaccharide was composed of glucose with α-(1 → 4)-linkages with short exterior chains. The fundamental information obtained from this work is beneficial to the interpretation in the relationship of the polysaccharide structure and its biological functions, and suggests that the polysaccharide from mussel may contribute to be used as a dietary supplement for health foods and therapeutics.
