以湘西野葛根为原料，在单因素实验基础上，采用响应面法优化大孔吸附树脂分离葛根总多酚的工艺条件，考察了 pH 值、吸附时间和吸附温度对总多酚提取率的影响，并建立了数学模型。结果表明，在 pH 值为6．0、吸附时间为180 min、吸附温度为59℃的最佳工艺条件下，总多酚提取率为0．2623％，比模型预测值（0．2636％）小0．0013％。
以湘西野葛根為原料，在單因素實驗基礎上，採用響應麵法優化大孔吸附樹脂分離葛根總多酚的工藝條件，攷察瞭 pH 值、吸附時間和吸附溫度對總多酚提取率的影響，併建立瞭數學模型。結果錶明，在 pH 值為6．0、吸附時間為180 min、吸附溫度為59℃的最佳工藝條件下，總多酚提取率為0．2623％，比模型預測值（0．2636％）小0．0013％。

With Pueraria lobata root as raw material,separation process of total polyphenol by macroporous adsorption resin was optimized by response surface methodology based on single factor experiment.Effects of pH value,adsorption time and adsorption temperature on extraction rate of total polyphenol were investigated. Mathematic model was established.Results showed that,under the optimum conditions of pH value 6.0,adsorp-tion time 180 min,adsorption temperature 59 ℃,extraction rate of total polyphenol was 0.2623%,which was 0.0013% less than model predicted value(0.2636%).
