Abstract: Polyphenols extracted from the fruit of Malus hupehensis(Pamp.)Rehd. On the basis of single factor experiments,the optimum conditions for the extraction of the polyphenols were obtained through Box-Benhnken center-united experiment design and response surface methodology. Response surface model R2 was 0.990 4,P<0.001,the model was highly significant and fitted well with the actual situation of the test. The results showed that the optimum conditions of extraction of the polyphenols were as follows: ethanol concentration 61%,time 3.0 h, liquid to raw material ratio 21∶1, temperature 85 ℃. Under this condition,the maximal yield of polyphenols was up to 11.89 mg/g.
