ACIDIC POLYSACCHARIDE FRACTIONS OF GINSENG EXTRACT AND PROCESS FOR PRODUCING THE SAME

摘要

PURPOSE: Provided are acidic polysaccharide fractions separated from aqueous extract of ginseng, which contain uronic acid and prevent growth and activity of Helicobacter pylori in the stomach and intestines, thereby which can be used as a remedy material for a gastroenteric disease. CONSTITUTION: The acidic polysaccharide fractions are produced by a process comprising the steps of: grinding the ginseng and extracting insoluble fractions by using a phosphate buffer solution; extracting the insoluble fractions with distilled water; precipitating the insoluble fractions by using ethanol and dissolving the precipitate in the phosphate buffer solution; performing dialysis and ion exchange chromatography; eluting the acidic polysaccharide fractions containing 25-35wt.% of the uronic acid by using 0-1M sodium chloride.
