ABSTRACT

Objective:

To evaluate effect of refining of the aqneous extract solution of compound Chinese traditional medicine by microfiltration technique of inorganic ceramic membrane.

Methods:

The aqneous extract solution of Ephedra, Apricot kernel, Gypsum, and Licorice Decoction and Redujing Granules were processed by microfiltration technique of inorganic ceramic membrane. The changes in the characters, whole solids and effective componds before and after process were studied.

Results:

The aqueous extract solution of compound Chinese traditional medicine all were turbid before microfiltering and became clear after microfiltrating. The whole solid of Ephedra, Apricot kernel, Gypsum, and Licorice Decoction were decreased by 16.12%, and the lost rates of ephedrine and amygdalin were 20.11% and 18.06% respectively. The whole solid of Redujing Granules were decreased by 27.58%, and the lost rates of chlorogenic acid and rhein were 18.28% and 22.86% respectively.

Conclusion:

The microfiltration technology of inorganic ceramic membrane has the better effects of clarification and removing impurity on the aqueous extract solution of compound Chinese traditional medicine.
