无机陶瓷膜微滤技术精制麻杏石甘汤和热毒净颗粒的研究

目的：对无机陶瓷膜微滤技术精制中药复方水提液的效果进行初步评价。方法：用孔径为0．2μm的无机陶瓷膜对麻木叶石甘汤和热净颗粒的提液进行微滤，对水提液微滤前后在性状、总固体、指标成分等方面的变化进行对比分析。结果：复方水提液微滤前均为浑浊液体，微滤后成为颜色变浅的澄明液体，麻杏石甘汤总固体去除率为16．12％，麻黄碱和苦杏仁甙的损失率分别为20．11％和18．16％。热毒净颗粒总固体去除率为27．58％，绿原酸和大黄酸的损失率分别为18．28％和22．86％。结论：无机陶瓷膜微滤技术对中药复方水提液具有较好的澄清除杂效果。

Study on Refining of Ephedra, Apricot kernel, Gypsum, and Licorice Decoction and Redujing Granules by Microfiltration Technique of Inorganic Ceramic Membrane

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.
