Application of Dynamic Ultrasound Countercurrent Extraction Technology in Industrialization of Lianhua Qingwen Capsule

Objective To study the application of dynamic ultrasound countercurrent extraction technology in industrialization of Lianhua Qingwen Capsule by multi-index optimization. Methods Ultrasonic temperature and ultrasonic time were investigated by using single factor design. The three factors of dry extract yield, the active ingredient content, and fingerprints were selected as the optimization indexes to investigate the solvent consumption and extraction time between the dynamic ultrasound countercurrent extraction process and the original reflux extraction process under the fixed conditions of process parameters. Results Compared with traditional reflux extraction technology, dynamic ultrasound countercurrent extraction technology effectively reduced the alcohol consumption and saved extraction time on the basis of guarantee of the active ingredient content. Conclusion Dynamic ultrasound countercurrent extraction process, with simple and fast advantages, can be used to Lianhua Qingwen Capsule production, which can significantly reduce production costs and increase productivity.
