摘要: 以红枣为原料提取红枣黄酮,通过吸附树脂的筛选,探讨树脂吸附的溶液浓度、pH值、吸附时间、吸附液体积对树脂吸附条件的影响。利用Box-Behnken中心组合设计原理,应用响应曲面分析方法,确定了大孔吸附树脂对红枣黄酮最佳吸附条件为:最佳吸附树脂为XDA-8,吸附时间62 min,吸附液浓度为4.3 mg/L,pH值为7.32,吸附液体积为10 mL,最大吸附效率达到85.64%,优化后得实际吸附率为85.51%。

Abstract: Adsorption and desorption characteristic of different resins for total flavonoid from Jujube was investigated. The experiment was conducted to study the effects of resin adsorption conditions on adsorption rate of flavonoid, and the adsorption time, pH, volume and concentration were developed. By the Box-Behnken centre united experiment design and response surface methodology, the optimum adsorption conditions were developed using resin XDA-8. The adsorption time was 62 min, volume value 10 mL, pH value 7.32 and the concentration was 4 mg/L. Under the optimum condition, the sample adsorption rate was 85.64%, and the actual rate of adsorption was 85.51%.

Key words: resin, Jujube, response surface methodology
