The invention discloses a preparing method for gynura divaricata polysaccharide with the hypoglycemic effect. According to the scheme I, after a water extraction and alcohol sedimentation method is used for obtaining crude polysaccharide, a method of combining macroporous adsorption resin and macroporous anion exchange resin with a ZTC natural clarifying agent is adopted, finally a dialysis method is used for removing micromolecule substances to obtain the gynura divaricata polysaccharide, and the ZTC natural clarifying agent can achieve a good flocculation effect to remove protein, tannins and macromolecule inorganic salt substances; according to the scheme II, after the water extraction and alcohol sedimentation method is used for obtaining the crude polysaccharide, a method of combining macroporous adsorption resin and the macroporous anion exchange resin with phenols adsorbent polyvinylpyrrolidone is adopted for obtaining the gynura divaricata polysaccharide through dialysis; the content ...
