Abstract

Wolfberry glycopeptide composition and methods for preparing and using the same, the part with a molecular weight distribution of 1000 Da to 10000 Da of the wolfberry glycopeptide accounts for 50-85% on the HPLC differential refractive index map; and the protein content is 20-35% weight percentage, neutral polysaccharide content is 20-35% weight percentage. Optionally, the uronic acid content is 5-20% weight percentage. The preparation method of the present invention removes part of insoluble impurities by a heating flocculation method, instead of the conventional organic solvent extraction process, and without using any organic solvents in the whole process.
