Abstract: With Zanthoxylum bungeagum seed as test raw material,adsorption separation technology of total polyphenol by macroporous resin was optimizated by response surface methodology on basis single-factor experiment.Influence of pH,adsorption temperature and time on extraction yield of total polyphenols was investigated.Mathematic model was established,and the significance testing and variance analysis were accomplished.Experimental results show that extraction ratio of total polyphenol was 3.862 7% at 70 ℃ adsouption in pH 6.0 for 90 min.The predicted value of experimental model was 3.929 7.Experimental results decreased by 0.062 5% in comparison with predicted content of model.

Key words: Zanthoxylum bungeagum, total polyphenol, adsorption separation, response surface methodology
