Abstract: The properties of static and dynamic adsorption and desorption of macroporous resin for Resveratrol were investigated. The H103 resin was selected to purify Resveratrol. The effects of concentration, pH and work speed of the infusion on the adsorption of the H103 resin were studied with static experiment. The concentration of 0.7157mg/ml, pH 4.10 and work speed of 2BV/h were the optimal conditions. Resveratrol absorbed on H103 resin was eluted with 4BV 80% ethanol in 1BV/h speed.

Key words: macroporous resin, Polygonum cuspidatum Sieb. et Zucc, Resveratrol
