摘要: 以雪胆(Hemsleya chinensis)为试验材料,采用Box-Behnken中心组合设计响应面优化的方法,优化雪胆多酚的提取工艺条件。以多酚提取率作指标,通过Design-Expert 8.0.6软件,基于单因素试验结果,建立雪胆多酚提取率与提取温度、乙醇浓度、液料比、提取时间4因素3水平的数学模型。结果表明,雪胆多酚提取率模型拟合度较好,显著性高,优化后的最佳提取工艺条件为提取时间59 min、乙醇浓度(V/V)50%、提取温度74 ℃、液料比16∶1(mL/g),此条件下雪胆多酚提取率为(1.479 6±0.004 1) mg/g。

Abstract: Taking Hemsleya chinensis as the experimental material, the Box-Behnken central composite design and response surface methodology were used to optimize the extraction conditions of polyphenols from Hemsleya chinensis. The extraction rate of polyphenols was used as index. Based on the results single factor experiments, a mathematical model of 4 factors and 3 levels center combinations was established with the Design-Expert 8.0.6 software on the extraction temperature, ethanol concentration, liquid to material ratio, extraction time. The results showed that the fitting degree of polyphenol extraction rate model was good and significant. The best process parameters were extraction time 59 min, ethanol concentration (V/V) 50 %, extraction temperature 74 ℃, and liquid to material ratio 16∶1(mL/g). Under these conditions, the extraction rate of polyphenols from H. chinensis was (1.479 6±0.004 1) mg/g.

Key words: Hemsleya chinensis, polyphenols, extraction, response surface methodology
