Abstract: This article studied absorbing and s eparating of the red pigment of Bougainvillea spectabilis Willd with AB -8resin .We compared the four resins.The results showed that four resins have the best performance of ab-sorbingtotheredpigmentof Bougainvillea spectabilisWilld.Inthecourseofdesorbingtheabsorbedredpigmentof Bougainvillea spectabilisWilld with40%ethanol,we selectedAB -8re sinduring the experiment.After using of20times,the absorption factor was very stabilization.

Key words: Bougainvillea spectabilis Willd red pigment, AB -8resin, absorbing
