| 摘 要： | 目的:研究树脂分离纯化五倍子中没食子酸的工艺,为工业化生产提供实验依据。方法:选取10种型号的树脂进行纯化实验,利用静态吸附和动态吸附的方法,研究树脂纯化五倍子中没食子酸的工艺条件。结果:D301型离子交换树脂能更有效地纯化没食子酸。当上样浓度为3.316mg/mL,速率为1mL/min,上样液体积为12BV时,树脂达到动态饱和吸附。再用18BV70%乙醇,以1mL/min的速率可以洗脱完全。经过树脂的纯化,没食子酸的纯度由原来的42.4%提高到68.8%。结论:树脂D301离子交换树脂对五倍子中没食子酸有一定的纯化作用,但效率一般。

| Abstract: | Objective:A method for separation and purification of gallic acid from Chinese gall with resin was studied. Methods:10 models of resins were selected for purification test,the technical conditions for purification of the gallic acid in Chinese gall with resin was studied by using the absorption of static and dynamic state. Results:The resin of Model D301 could purify the gallic acid in Chinese gall much effectively. When the sampling concentration was 3.316mg/mL,the sampling flow rate was 1mL/min,sampling v... |
