摘要
目的:使用合适的方法表征中药粉体的流动性。方法:以流动性较好的直压辅料与中药粉体为原料,对物料粉体使用Carr法和Jenike法测定了流动性。结果:Carr法表征的中药提取物流动性和辅料流动性和Jenike法相差不大,中药提取物流动性明显不如直压辅料。结论:从综合Carr法和Jenike法对各种粉体学表征结果来看,Carr法表征的中药提取物流动性与实际符合较好,Jenike法可以用来指导进料系统的设计。
Objective： To characterize the flowability of traditional Chinese medicine（TCM） powders by using appropriate methods.Method： With highly flowable direct compression excipients and Chinese traditional medicine powder as raw materials,the flowability of material powders is determined by the Carr method and the Jenike method.Result： The Carr method and the Jenike method for the determination of the flowability of Chinese herb extract powder and direct-pressing excipients have no obvious difference.But the flowability of Chinese herb extract powder is not as good as direct compression excipients.Conclusion： From the characterization results of both methods,we can find that the Carr method better reflects the actual flowability of TCM extracts,while the Jenike method can be used for guiding the design of the hopper device.
