摘　　要：目的选择较合适的大孔吸附树脂,对当归中阿魏酸进行富集纯化,提高产品质量。方法采用大孔吸附树脂对阿魏酸进行吸附及洗脱性能试验,同时采用HPLC法进行分析检测。结果筛选出较合适的吸附树脂DA201,得到了最佳的工艺参数,使阿魏酸的质量分数由原材料中的0.15%富集提高到25.1%。结论该工艺成本低,效果好,树脂可重复使用,对于当归中阿魏酸的纯化有很好的应用前景。Objective To select the suitable macroporous adsorption resins for enrichment and purification ferulic acid from Angelica sinensis so as to improve the product quality. Methods Macroporous adsorption resins were used to study the adsorption and desorption characteristics of ferulic acid. At the same time HPLC was used in detection. Results The best resin DA201 was chosen and the optimum parameters were obtained. The content of ferulic acid was increased from 0.15%; in the raw material to 25.1%. Conclusion The material has a low cost and the operation is easy. The adsorption resins can be used again, which has a good applied foreground.
