摘　　要：目的 :简要讨论醇沉过程中分离程度对中药质量、保质期等的影响。方法 :根据颗粒沉降速度的计算结果对不同剂型药物的生产工艺进行控制。结果 :醇沉过程中颗粒在不同温度、乙醇浓度和分离条件下需要采用不同的分离因数对其进行分离。结论 :在中药生产过程中 。Objective: The effect of separation rates on the quality and shelf life of TCM in the process of alcohol precipitation was discussed. Methods: According to the sedimentation rate, controlling process was chosen for different doses of medicine. Results: In the process of alcohol sedimentation, different centrifugal coefficient was needed with the variation of conditions, such as temperature, concentration of alcohol and centrifugal coefficient, etc. Conclusion: The control parameters of the process of alcohol precipitation affect the efficacy and shelf life directly in the processing of TCM production.
