Abstract: The extraction technology of polyphenol from Chinese pistache meal was studied by response surface methodology. The optimized extraction conditions are as follows: pH 1.7, extraction temperature 50 ℃, ratio of solution to material 11.7 ml/g, and extraction time 69.60 min. By verification experiment, the maximum extraction rate of polyphenol from Chinese pistache meal is up to 27.6 mg/g.

Key words: Chinese pistache meal, polyphenol, response surface analysis, extraction, optimization
