摘要
研究超声波强化有机溶剂提取万寿菊花粉中叶黄素的工艺过程,考察了萃取率的影响因素。结果表明,正己烷和石油醚作提取溶剂效果较好。以1.000 g万寿菊花粉为原料,超声波强化正己烷的较优提取条件为:料液比1∶20(g∶mL,以下同),超声波功率300 W,超声波作用时间30 m in,叶黄素提取率93.65%;强化石油醚的较优条件为:料液比1∶20,超声波功率400 W,超声波作用时间30 m in,叶黄素提取率98.77%。
The use of ultrasonic-assisted solvent extraction of lutein from flower of marigold （ Tagetes erecta Linn. ） under different operating conditions was studied. Influences of solvent, ratio of material to liquid, ultrasonic power and ultrasonic treatment time on the extraction yield of lutein were studied. It was found that both n-hexane and petroleum ether were good solvent for ultrasonic-assisted process. Optimal ultrasonic-assisted n-hexane and petroleum ether extraction conditions for 1. 000 g marigold flower powder were： 1：20（g： mL） for ratio of material to liquid, 30 min for ultrasonic time, 300 W and 400 W for ultrasonic power, and extraction rates were 93.65 % and 98.77 %, respectively.
