Abstract
The purification by macroporous resin and antioxidant activity of flavonoids from zingiber were studied in this paper.The X-5 macroporous resin showed the best adsorption and desorption ability,comparing with other seven kind of macroporous resin.The best condition for purification was: adsorption at 30～35 ℃,elution agent(ethanol) concentration of 80%,1 mL/min washing flow,elution temperature 30 ℃.Under this condition,flavonoid yield was high and purity was stable.The flavonoids of zingiber had strong antioxidant activity in a certain range of concentration and the antioxidant activity of no purification was more significant than that of purification.
