Abstract: The purification of chlorogenic acid(CA) from sunflower seed meal with four kinds of commercial macroporous resins was studied.Results showed that HPD400 is the optimal resin owing to its bigger adsorption ratio and bigger desorption ratio. The adsorption characteristics of HPD400 resin were studied. It was found that the best conditions are adjusting CA concentration 2 mg/ml in sample at pH 3.0 and taking 40% ethanol at pH 6 as eluent.

Key words: sunflower seed meal, chlorogenic acid, macrorporous resin, purification
