对梅花鹿茸进行超微粉碎,并对鹿茸细粉和微粉的粉体学特征进行了系统的比较研究。在扫描电子显微镜下观察了粉体的显微结构,通过激光粒度分析仪测定微粉粒径、粒径分布宽度和比表面积,检测粉体的休止角、堆密度、水溶性蛋白含量和水溶性浸出物的累计溶出度。结果表明微粉化使鹿茸粉体粒径明显变小,比表面积增大,能增加鹿茸水溶性蛋白质和水溶性浸出物的溶出度,可充分有效的利用鹿茸,增强药效,为开发新剂型奠定了基础。 The sika deer antler was ultrafinely comminuted, and the powdery characteristics of the antler powder and micropowder were systematically and comparatively studied. The microstructure of the powder was observed under a scanning electron microscope. The particle size, particle size distribution and specific surface area of ​​the powder were measured by laser particle size analyzer. The angle of repose, bulk density, water-soluble protein content and water- The cumulative dissolution of matter. The results showed that the micronization of the antler powder particle size significantly smaller, specific surface area increased, can increase the antler water-soluble protein and water-soluble extract of the dissolution rate can be fully effective use of antler, enhance efficacy, lay the foundation for the development of new formulations The foundation.
