Abstract: Resveratrol is purified by macroporous adsorption resin from polygonum cuspidatum .The experiment results show that a resin type of NKA-9 is better in adsorption and desorption to resveratrol. Resveratrol can be purified well under the condition of material concentration 3~4mg/ml, sample flow velocity 1ml/min, sample quantity 0.5BV, pH=4 for adsorption; 75% ethanol as desorption solvent, desorption velocity of flow 1.0ml/min, pH=8 for desorption.

Key words: resveratrol, macroporous adsorption resin, polygonum cuspidatum, purification
