ABSTRACT
Objective: In order to improve the technology of Chinese medicine extraction, experiments were made with large pore size ultrafiltration (LPS UF) membranes in the process of Chinese medicine production, and the feasibility of replacing traditional alcohol sedimentation with LPS UF method in the production of compound Chinese medicine was also explored. Methods: The water extraction liquid of Shenbao Mixture with alcohol percolation extract was ultrafiltered. Icariin as index component was determined. Results: Component of Icariin was reserved as 90%, this technology was similar to alcohol extraction. Conclusion: The experiments on the extraction of “Shengbao” mixture show that the LPS UF membranes with MWCO above 100,000 were more effective in retaining the effective ingredients and removing the precipitates.
