摘要

优化离子液体超声辅助提取黑果腺肋花楸果中花青素的工艺条件。以花青素的提取率为指标，通过单因素与正交试验相结合的方式探索离子液体超声辅助提取黑果腺肋花楸果中花青素的工艺参数。试验结果表明：提取溶剂乙醇的体积分数为80%，料液比为1:25，提取温度为65 ℃，提取时间为3 h，超声波功率70 W，离子液体为溴化-1-丁基-3-甲基咪唑，离子液体浓度为0.5 mol/L，在优化的提取工艺条件下，花青素的提取率可以达到8.8242 mg/g。优化的离子液体超声辅助提取黑果腺肋花楸果中花青素的提取率高，为黑果腺肋花楸果的开发利用提供了依据。

Abstract:

Optimize the process conditions for the extraction of Anthocyanin from Aronia melanocarpa Fruit by Ionic liquid Ultrasound Assisted. Using the extraction rate of anthocyanins as an index, the method of ultrasonic assisted extraction of anthocyanins from the fruit of the Aronia melanocarpa was studied by single factor and orthogonal experiment. The results showed that the optimal conditions were ethanol concentration 80%, liquid solid ratio 1:25, extraction temperature 65 ℃, extraction time 3 h, ultrasonic power 70 W,1-butyl-3-methylimidazolium bromide was identified as the ionic liquid used in the subsequent experiments, and the concentration was 0.5 mol/L. Under the optimized extraction process conditions, the extraction rate of Anthocyanin can reach 8.8242 mg/g. The extraction rate of Anthocyanin from Aronia melanocarpa Fruit by optimized Ionic liquid Ultrasound Assisted is high, that provides the basis for the development and utilization of the Aronia melanocarpa Fruit.
