Title: Purification technology for polyphenols from litchi Pericarp by column chromatography.
Abstract: Adsorption and desorption experiments were carried out to screen the suitable macroporous absorbent resin for polyphends from lichee Pericarp. The results indicate that macroporous resin XDA-7 possesses strong absorbend ability and desorbing property.The optimum absorption conditions for macroporous resin XDA-7 are concentration of feed 3.5 mg/mL,pH value≤4.5,feeding rate 2~4 BV/h. And the optimum desorption conditions are elute-ethanol concentration 6 mg/mL,elution rate 6 BV/h.Purified under this condition,the obtained polyphenol product is of the purity of 70.6%.
