Abstract: 【Objective】 In this study, D-101 macroporous adsorption resin was used to separate and purify total flavonods from fruits of pomegranate cultivars from Xinjiang.【Method】 Based on the single factor study, the conditions for the separation and purification of total flavonoids from pomegranate skin by DX101 macroporous adsorption resin were further studied by investigating the temperature, pH, adsorption penetration curve, eluent concentration and ratio of material to liquid, and the optimum technological conditions were found.【Result】The optimal purification conditions were as follows:pH 3-4,temperature of 30℃, material ratio of 1∶4(g/mL), the volume of ethanol in the eluent was 90%. Under this process condition, the purity of total flavonoids in pomegranate peel increased from 7.25% to 17.32%. 【Conclusion】Under this process condition, the non-target ingredients, such as pigment and chlorophyll can be eluted effectively, and the total flavonoids of pomegranate cultivars of Xinjiang can be separated and purified scientifically and reasonably and the operation is simple, safe and of low cost.

摘要: 【目的】研究采用D-101大孔吸附树脂分离纯化新疆石榴皮中的总黄酮。【方法】以单因素为研究基础,分析温度、pH、吸附穿透曲线及洗脱液浓度、料液比等因素,研究D-101大孔吸附树脂分离纯化石榴皮总黄酮的条件,并找到最佳工艺条件。【结果】D101大孔吸附树脂对石榴皮中黄酮类物质纯化的最佳工艺为:提取液pH为4、温度30℃、料液比1∶4(g/mL)、洗脱液乙醇体积为90%。该工艺富集纯化石榴皮黄酮类物质效果较好,石皮总黄酮的纯度由7.25%提高至17.32%。【结论】能有效的洗脱色素、叶绿素等非目标成分,科学合理的分离纯化石榴皮中总黄酮,且操作简单、安全、成本低廉。
