Absorption and desorption experiments were performed to screen the suitable resin from 6 types of macroporous absorbent resins for the purification of tobacco polyphenol from discarded tobacco leaves.Results indicate that macroporous resin D101 possesses the strongest absorption and desorption capacity.The optimal absorption and desorption condition of macroporous resin D101 is the concentration of feeding solution 2.5 mg/mL,pH value 4.0,feeding rate 2.0 mL/min,elute ethanol concentration 80%,elution rate 2.0 mL/min.The dynamic recovery of tobacco polyphenol was 70.37% under the optimal condition.
