Abstract: The adsorption and desorption of macro-porous resin on Aspergillus-type Douchi melanoidin were studied.The results showed that the sorption of X-5 resin is optimum.The study also showed that the X-resin has greater sorption at pH6.0,concentration 30.12 mg/ml and flow speed 1.5ml/min.With concentration of alcohol 60%,the desorption is the most effective at 1.5 ml/min and normal temperature.

Key words: Aspergillus-type Douchi melanoidin, macro-porous resin, purification
