目的:考察不同型号大孔树脂对金荞麦中有效成分的纯化效果。方法:以表儿茶素和金E的含量、浸膏率为指标,结合HPLC指纹图谱,选择最佳型号大孔树脂。结果:AB-8型大孔树脂对表儿茶素洗脱率为89.78%,对金E洗脱率为93.04%。HPLC指纹图谱共有峰面积比较表明AB-8型大孔树脂最适合用于金荞麦有效成分的纯化。结论:采用AB-8型大孔树脂纯化金荞麦中有效成分是可行的,且操作简单、稳定。 OBJECTIVE: To investigate the purification effect of different types of macroporous resin on the active ingredients in Fagopyrum. Methods: The epicatechin and gold E content, extract rate as an indicator, combined with HPLC fingerprints, choose the best model macroporous resin. Results: The elution rate of epicatechin was 89.78% for AB-8 macroporous resin and 93.04% for gold E. The comparison of the peak area of ​​HPLC fingerprints showed that AB-8 macroporous resin is the most suitable for the purification of the active ingredients of buckwheat. Conclusion: It is feasible to purify the active ingredients of F buckle with AB-8 macroporous resin, and the operation is simple and stable.
