摘　　要：目的:对紫河车细粉和超微细粉体进行表征研究。方法:先用中草药粉碎机将紫河车粉碎成细粉,然后用倍力微粉机对细粉进行超微粉碎;用扫描电镜和粒径测定仪表征。结果细粉与超细粉的d10分别为16.05μm、9.37μm,d50分别为96.69μm、50.57μm,d90分别212.8μm、148.21μm,分布宽度分别为2.035、2.745。结论:经过超微粉碎后,粉体外观性状得到改善。Objective ：to study the characterization of the fine powder and the superfine powder of Placenta Homins. Methods ： Placenta Homins was crushed to make fine powder with vegetation disintegrator firstly, then the fine powder was crushed to make superfine powder with Beili micro pulverize, study the characterization of the powder by Mastersizer Microplus instrument of granularity and scanning electron microscope （SEM）. Results ：The d10 of the fine powder and the superfine powder were 16. 05μm and 9.371xm,the d50 were 96.69μm and 50.5μm,the d90 were 212.8μm and 148.21 μm,the SPAN were 2. 035 and 2. 745. Conclusion ：The appearance of the superfine powder of Ptacenta Hominis was better than the fine power.
