| Abstract: |
| Objective: To investigate the effect of different pore diameter membranes on the technologies of water extract from Shuanghuanglian and compared with the traditional alcohol precipitation and removal process to optimize the impurity removal method during the preparation of Shuanghuanglian Effervescent Tablets. Methods: Five different membranes of 50nm、100nm、200nm、450nm and 800nm were tested to observe the changes in membrane flux, drug solution traits, the retention of effective components and solids removal；Taking the content of chlorogenic acid, baicalin and forsythin in Shuanghuanglian effervescent tablets as the inspection index, the membrane filtration impurity removal was compared with the traditional alcohol precipitation and impurity removal process. Results: The results showed that the filtration efficiency of the filtrate of waterSextract from honeysuckleSflower and forsythia was better when the ceramic membrane with 450 nm pore size was filtered. The filtrate was clear and transparent. The membrane flux and chlorogenic acid and forsythin transfer rate were high, Removal rate higher. The ceramic membrane with 200 nm pore size was better for waterSextract from ScutellariaeSRadix which was adjustedStheSpH; The content of active ingredients in Shuanghuanglian Effervescent Tablets prepared by membrane filtration and impurity removal is better than that of alcohols. Conclusion: Membrane separation technology can be applied to the preparation of Shuanghuanglian Effervescent Tablets in the process of impurity removal. |
