摘　　要：目的通过对甘草、丹参、黄连三种常用中药进行超微粉碎,比较所得微粉与常规粉碎的药材细粉在有效成分含量测定结果、粉体流动性、松密度等几方面的异同,为微米中药质量标准的建立提供依据。方法利用倍力超微粉碎技术进行药材的超微粉碎。结果微粉有效成分含量测定结果有所提高,松密度较恒定且变大、流动性稍差。结论药材经超微粉碎,有效成分含量测定结果变大,微粉粒子粒径均匀。Objective： Through the comparative study to the effective ingredient content, powder liquidity and bulk density,etc of the micro powder and fine powder of three common traditional Chinese medicinal materias： Radix Glycyrrhizae,Radix Salviae Militiorrhizae and Rhizoma Coptidis, reference can he supplied to the establishment of the identification and quality standard of micrometer traditional Chinese medicine. Methods： Use punchy attritioning technology to attrite the medicine. Results： The effective ingredient content of the micro powder rises, the bulk density is quite constant and getting larger and the liquidity is a little worse. Conclusion： Alter the traditional Chinese medicinal materias are attrited, the effective ingredient content rises and the particle size is uniform.
