    Abstract:
    OBJECTIVE: To study on the formulation and process of Da Chuan Xiong Fang pellet by extrusion-spheronization. METHODS: Based on the physical characters of active parts, the fast-release pellets of Chuan Xiong and Tian Ma were prepared separately by extrusion-spheronization. The formulation and process were studied by direct comparison. Then their characters were evaluated. RESULTS: The active components could release more than 90% in 30 minutes and the pellets presented perfect sphericity and narrow diameter distribution. CONCLUSION: Pellets of TCM can be prepared by homemade extrusion-spheronization machine and the fast-release pellets show perfect sphericity and narrow diameter distribution.
