中文摘要: 为高效获得花青素，采用离子液体-微波辅助提取黑豆皮中的花青素，考察提取时间、提取温度、微波功率、离子液体浓度、料液比对提取量的影响，采用响应曲面法对提取工艺进行优化。结果表明，最佳提取条件为提取时间45 min，离子液体浓度0.7 mol/L，料液比1∶30（g/mL），微波功率460 W，提取温度49℃。在此条件下，花青素的提取量为4.834 mg/g，预测值和实际测定值接近，可以为黑豆皮花青素后续的利用和研发提供参考。

Abstract:In order to obtain anthocyanin efficiently，the extraction of black soybean coats anthocyanin by ionic liquid ultrasound was studied.The effects of extraction time，temperature，microwave power，ionic liquid concentration and solid-liquid ratio on the extraction amount were investigated.The extraction process was optimized by response surface methodology.The results showed that the optimum extraction conditions were as follows：extraction time 45 min，ionic liquid concentration 0.7 mol/L，solid-liquid ratio 1 ∶30（g/mL），microwave power 460 W，extraction temperature 49℃.Under these conditions，the yield of anthocyanin from black soybean coats was 4.834 mg/g，and the predicted value is close to the actual measured value，which can provide a basis for the comprehensive development and follow-up research of anthocyanin from black soybean coats.
