摘要: 利用星点设计-响应面分析法((CCD- RSM)优化蜂胶总多酚的超声提取工艺。在单因素试验基础上,选取超声时间、液料比和乙醇体积分数为影响因子,以Folin- Ciocalteus法测定总多酚的含量作为响应值进行响应面分析,确定最佳提取条件。结果表明:超声提取时间24.0min,乙醇体积分数77.0%,料液比1:14 g / mL时,实验平均值为3.34% (n=3,R=0.14%),单因素最佳实验条件测定总多酚含量为2.86%,优于单因素考察结果。该方法简单快速有效,提高了蜂胶中总多酚的提取率。

Abstract: Central composite design and response surface ((CCD-RSM) was employed to optimize the ultrasonic extraction conditions of total polyphenol from propolis . Based on single factor experiments, the ultrasonic time, liquid material ratio and ethanol concentration were investigated.With Folin-Ciocalteus determining the total polyphenol , the value was analied to determine the best extraction conditions. The results showed that the optimal extraction conditions :the extraction time, ethanol concentration and solid-to-liquid ratio were 24.0 min, 77.0%and1:14 (g/mL), respectively. the experimental average value is 3.34% (n = 3 ,R=0.14%) , the total polyphenol content of propolis was 2.86% from best experimental conditions of single factor,better than the results of single factor.This method is simple, rapid and effective, and improve the extraction of polyphenols in propolis
