摘要:

考察不同乙醇体积分数、浸提温度、浸提时间、料液比对红枣渣中芦丁提取的影响,优化了提取工艺。结果表明:在料液比1:40(m/V)、乙醇体积分数69%、浸提时间8.5h、浸提温度70℃的条件下芦丁提取量最大,为155.46mg/100g。

Abstract:

The effects of ethanol concentration, temperature, extraction time and ratio of material to liquid on the extraction of rutin from Chinese jujube residue were investigated. Subsequently, a central composite design leading to 17 experiments of the other three variables expect ratio of material to liquid at three levels combined with response surface methodology was employed to maximize rutin extraction. The optimum extraction conditions were determined as follows: ratio of liquid to solid 1:40 (m/V), ethanol concentration 69%, and temperature 70 ℃ for an extraction duration of 8.5 h, and under these conditions, the maximum extraction rate of 155.46 mg/100 g was obtained.

Key words: Chinese jujube residue, extraction technology, rutin
