Hematopoietic, myeloprotecting, antitumor immune cells generating and radiosensitizing polysaccharide isolated from Panax ginseng

摘要

The present invention relates to a polysaccharide composition having the hematopoietic, myeloprotecting, antitumor immune cell generating, and radiosensitizing activities extracted from the roots of Panax ginseng prepared by the steps of:i) obtaining the residue by extracting 1 wt part of ginseng roots with 2~4 wt part of methanol;ii) extracting and obtaining the water soluble fraction from the residue in step i) using 3~5 wt part of distilled water;iii) freeze-drying the obtained water soluble fraction in step ii);iv) obtaining the inner fraction using the dialysis membrane after obtaining the insoluble fraction to the 40% of ethanol from freeze-dried fraction in step iii);v) obtaining the 6 fractions by sephacryl S-500 gel chromatography; andvi) purifying the polysaccharide by DEAE-sephadex A-50 chromatography.
