摘要
采用响应曲面分析法对女贞子多酚的提取工艺进行优化。单因素试验的基础上,选取四因素三水平的BoxBehnken研究方法优化多酚提取工艺。女贞子多酚最优提取工艺为:提取时间69.60 min、提取功率480 W、液料比80∶1(mL/g)、乙醇体积分数59.21%。在此条件下女贞子多酚提取率为6.527%。最优条件下提取的女贞子多酚能有效抑制大肠杆菌、金黄色葡萄球菌和枯草芽孢杆菌的增殖。
The optimization of the extraction process of polyphenols from Ligustrum lucidum Ait was achievedby response surface methodology. On the basis of single-factor experiments, the method of Box-Behnken designwith four factors and three levels was adopted to optimize the extraction process of polyphenols. The optimumconditions for extracting polyphenols from Ligustrum lucidum Ait were found to be：extraction time 69.60 min,extraction power 480W,liquid-solid ratio 80 颐 1（mL/g）and ethanol concentration 59.21 %. Under theseconditions,the yield of polyphenols from Ligustrum lucidum Ait was 6.527 %. The polyphenols extracted fromLigustrum lucidum Ait under the optimum conditions were effective to suppress the proliferation of Escherichiacoli, Staphylococcus aureus and Bacillus subtilis.
