Abstract: The adsorption and desorption of the pigment of Lycium ruthenicum Murr. with macroporous resin is studied. The results show that resin X-5 has higher adsorption capacity, at pH3.0, which adsorption capacity is 37.15mg/ml resin; Eluting with 95% ethanol from X-5 resin, the pigment can be gotten more than 97.78% of that all. The pigment producted by this method is purple power, and its colour value is 36.7.

Key words: pigment of Lycium ruthenicum Murr., macroporous resin, adsorption, desorption
