Effective Utilization of Residues after Total Saponins of Panax Notoginseng being Extracted to Distill Polysaccharides

After total saponins of Panax notoginseng were extracted,residues left was refined,separated,and purified.Then we obtained polysaccharides which are effective elements in panax pseudoginseng var.notoginseng.By testing,their content attained to 50%.It has been proved that re-development and utilization has been enhanced.
