目的 為了表征蒼術、黃柏及二妙丸的超細微粉,了解其理化特性。方法 采用掃描電子顯微鏡、生物顯微鑒別、粒徑、松密度及比表面積測定等方法對中藥普通粉和超細微粉進行了表征。結果 超細微粉顆粒大小均勻,90 %小于 2 0 μm,比表面提高 6 0 %～ 190 %,松密度約為 0 .42 g/ cm3,絕大多數細胞被破碎。結論 蒼術、黃柏及二妙丸經超細微化后,粉末顆粒大小均勻,球性度及均質度明顯改善 ;松密度及比表面顯著提高,植物細胞破壁率高。

Object To characterize the ultra-fine particles of Atractylodes lancea (Thunb.) DC., Phellodendron chinense Schneid and the ERMIAO PILL, a compounded preparation of the above two drugs, for the purpose to observe a deeper view on their physico-chemical properties. Methods By comparing their particle size, porosity and specific surface area with light and scanning electron microscope. Results The size of the ultra-fine particles were more uniform in size, 90% of which were under 20 μm, their specific area were increased by 60% ～ 190% and bulk density were around 0.42 g/cm3, and the great majority of the plant cells were broken as compared with the conventional coarse powder. Conclusion Both A. lancea and P. chinense together with their combined preparation became smaller in particle size, more uniformly distributed with increased specific surface area and broken cell wall.
