摘    要:以叶黄素酯为原料,对万寿菊花中叶黄素酯皂化反应的工艺进行优化,考察反应溶剂种类及用量、皂化温度、皂化时间等因素对皂化反应的影响,采用薄层层析法计算皂化率,确定叶黄素酯皂化的适宜操作条件,对皂化反应工艺进行单因素试验和响应面分析研究。结果表明,叶黄素酯的皂化反应最佳工艺条件为叶黄素酯为2.0 g时,无水乙醇用量31.3 mL、皂化温度60 ℃、KOH用量2.1 g、皂化时间4 h,此条件下叶黄素酯的平均皂化率为78.4%。

关 键 词:叶黄素酯  皂化反应  薄层层析法

Abstract:This work was conducted to investigate the saponification of lutein esters from marigold flowers. The effects
of type and amount of organic solvent, saponification temperature and time on the saponification rate of lutein esters as
determined by thin layer chromatography were explored. The optimal conditions for the saponification of lutein esters were
determined by single factor experiment and response surface analysis as follows: 2.0 g of lutein esters, 31.3 mL of absolute
ethanol, 2.1 g of potassium hydroxide, a saponification temperature of 60 ℃, and a saponification duration of 4 hours. Under
these optimal conditions, the average saponification rate of lutein esters reached 78.4%.
Keywords:lutein esters  saponification  thin layer chromatography
