| Abstract: | Adsorption and desorpfion experiments were carried out to screen the suitable macroporous absorbent resin for grape seed polyphenols. Results indicate that macroporous resin AB-8 possesse the strongest absorbend ability and easier desorption property.The optimum absorption conditions of macroporous resin AB-8 are concentration of feeding 3.0 g/L, pH 4.5, feeding rate 3 BV/h. And the optimum desorption conditions are eluteethanol concentration 80 %, elution rate 3 BV/h.Purified under this condition, the obtained polyphenols product have 81.1% purity. |
