A Study on Physicochemical Changes in the Process of Preparing Traditional Chinese Drugs

Objective:Summarizing the physicochemical changes in the process of preparing traditional Chinese drugs and affording useful clues for the quality improvement of Chinese patent drugs.Method:Introducing the main physicochemical changes,such as precipitating reaction,solubility increasing,hydrolysis,and oxidation reduction etc.,which occur in the process of extracting,separating, concentrating and drying.Result and Conclusion :The research of physicochemical changes occurring in the process of preparation and the probe into their mechanism play an important role in perfecting the basic theories of Chinese pharmacy ,promoting the development of compatibility theory of Chinese pharmary and improving the technology design for preparing and controlling the quality of Chinese patent drugs.
