摘要
利用AB-8大孔树脂纯化芫荽黄酮,通过静态和动态结合的方法,确定最佳工艺参数.结果表明,静态,吸附平衡时间为3 h,解析平衡时间为1.5 h;动态,上样液质量浓度为1.0 mg/mL,上样液pH值为6.0,上样流速为2 mL/min,洗脱剂质量浓度为70%乙醇溶液,洗脱流速为2 mL/min.在此条件下,AB-8大孔树脂可以较好的分离纯化芫荽中总黄酮.
AB-8 macroporous resin was used to separate and purify coriander flavonoids , static and dynamic adsorption and desorption behaviors of AB -8 macroporous resin were e-valuated for achieving the best purification of total flavonoids .The static：adsorption equilib-rium time was 4 h, desorption time was 1.5 h.The dynamic：the best adsorption was sample concentration of 1.0 mg/mL, pH of 6.0 and the flow rate of 2.0 mL/min.The desorption flow rate of 2.0 mL/min and 70% ethanol elution were the best .With definite technical process , the AB-8 macroporous resin could be used to purify the flavonoids of coriander .
