Study On The Superfine Comminution Technology Of Chinese Medicine Coptidis Rhizoma

The medicine utilization and released rate can be improved by superfine comminution of traditional Chinese medicine. The superfine comminution technology can also keep the active ingredients of medicine,save the amount of Chinese medicine,improve the traditional Chinese medicine taste and change the way of use.Using the frequency vibrated mill as test equipment, Coptidis Rhizoma is studyed with the help of powder engineering and medicinal chemistry.The paper has researched the vibrations fill rate,feeding size,different superfine comminution time as well as other different milling factors that have effects on superfine comminution of Coptidis Rhizoma. The paper comes to establish the superfine comminution technology process and gets the optimum condition of the traditional Chinese medicine Coptidis Rhizoma.The paper analyzes superfine comminution particle size with the laser particle size and electron microscope. The paper integrates medicinal chemistry and infraed absorption spectrum analysis to analyze and compare between superfine particle and common particle.Finally, the paper compares traditional Coptidis Rhizoma herbs decoction method with the Chinese superfine particle medicine instant drinks.
