摘 要:采用超声波辅助法提取红花中多酚类物质,在单因素基础上,选取对多酚收率影响较为显著的时间、温度、溶剂体积分数3个因素为自变量,以红花多酚为响应值,得到红花多酚的提取工艺优化条件。当提取时间35 min、提取温度55 ℃、乙醇体积分数55%、功率500 W、液料比40∶1(mL/g)时,红花多酚收率(5.974±0.100) μg/g,与预测值误差小于1.0%。

Abstract:Factors including extraction time, temperature and solvent volume fraction were selected as the independent variables while the content of polyphenol as the response value of safflower polyphenol. The results showed that: when the extraction time was of 35 min; the extraction temperature is 55 ℃; ethanol volume fraction was 55%; the power was 500 W; the liquid ratio was 40∶1(mL/g), the maximum rate of (5.974±0.100) μg/g safflower polyphenols was obtained with an error of less than 1.0%.
