摘要: 以黄连木饼粕为实验材料,在pH、提取温度、液料比和提取时间四个单因素试验的基础上,利用响应曲面试验设计法对粗多酚提取条件进行研究,并通过回归方程和响应曲面,得到的最佳提取工艺为:pH1.70、提取温度50℃、液料比11.7(ml/g)、提取时间69.60min。验证实验结果显示,此条件下多酚粗提率为27.65mg/g。

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.
