摘要: 通过对9种型号大孔吸附树脂静态筛选,最终确定AB-8型大孔吸附树脂用于沙枣果总黄酮化合物的富集,并通过动态实验,确定沙枣果总黄酮最优富集条件为:样品浓度2.43 mg·mL-1,上样速率2 BV·h-1,乙醇浓度70%,洗脱速率2 BV·h-1。在最优工艺条件下,沙枣果总黄酮浓度由9.73%增加到49.52%;其中金丝桃苷含量由0.53%增加到3.07%,提高5.79倍。本研究为沙枣果总黄酮的开发利用提供了理论依据。

Abstract: Based on the static screening experiments, AB-8 resin was determined to be the best resin for enriching flavonoid of Elaeagnus angustifolia from nine kinds of macro-porous resins. According to the dynamic experiment results, some enriching conditions were optimized, as follows:the sample concentration was 2.43 mg·mL-1; the flow rate was 2 BV·h-1; the ethanol concentration was 70%; the elution rate was 2 BV·h-1. The purity of total flavonoids from E. angustifolia was increased by 5.09 times, from 9.73% to 49.52%. The purity of Hypericin was increased by 5.79 times, from 0.53% to 3.07%. The results of this research would provide the theoretical basis and data support for the development and utilization of total flavonoids in E. angustifolia.

Key words: Elaeagnus angustifolia, flavonoids, enrichment
