摘要
目的:对吸附树脂常规再生方法的再生效果进行评价。方法:应用D101大孔吸附树脂,对淫羊藿总黄酮进行反复吸附、洗脱10次后,按常规方法进行再生处理;然后检测再生后树脂上淫羊藿总黄酮残留量,检测再生后树脂吸附容量,观察再生后树脂的变化。结果:在实验条件下,树脂柱上有前10次吸附平均收率0.6%的淫羊藿总黄酮残留量,再生后的吸附容量为24.30 mg·ml-1。结论:吸附树脂可连续多批次地用于同一产物的提取分离,再生后有提取物残留,吸附容量变化不大,再生后有利于提高树脂柱吸附过程的流动性。
Objective: To evaluate for recycle effect of recycle method of macroprous absorbent. Methods: Absorbing and washing total flavone from Epimedium brevicornum 10 times with D101 macroporous absorbent then recycle it with normal method. To test residum of total flavone and absorbing capacity of macroporous absorbent. Looking into the change of macroporous absorbent. Results: The residum of total flavone from Epimedium brevicornum was 0. 6%. The absorbing capacity was 24. 30 mg/ml. Conclusion:The macroporous absorbent can be used to continually abstract several groups of one production. There was extract residum. The absorbing capacity of macroporous absorbent changedlittle. Recycle is advantage for fluid of macroporous absorben.
