大孔树脂纯化灰毡毛忍冬中绿原酸的研究

Purification of Chlorogenic Acid from Lonicera macranthodes Hand-Mazz by NKA-9 Resin

摘要:

研究了大孔树脂纯化灰毡毛忍冬绿原酸的性能。结果表明大孔树脂NKA-9可用于灰毡毛忍冬中绿原酸粗提物的纯化，其最佳工艺为：洗脱液为45%乙醇，样液浓度为20%，样液pH值为5，上柱流速为0.5 BV/h，洗脱流速为1 BV/h，洗脱液用量为4 BV。

Abstract:

The purification of chlorogenic acid from Lonicera macranthodes Hand-Mazz by macro porous resin was studied. HPLC analysis showed that the purity and yield of achieved chlorogenic acid were 75.68% and 82.38%, respectively. The NKA-9 resin showed good properties of sorption and desorption.
