The results showed that the D50 of Astragalus membranaceus and Epimedium brevicornum ultra-fine powder were 6.82μm and 8.40μm separately. The broken cellular walls of two ultra-fine herbal powder were bigger than those of the commonly cribble, and intact cells were not visible under SEM, and it improved the mixed uniformity. On the contrary, organization blocks of the commonly cribble were clearly discernible, also the shape and granularity were irregular, and the organization cells were still complete. The bulk density and liquidity of Astragalus membranaceus and Epimedium brevicornum increased significantly after ultra-fine Smashing. The component icariin extraction content of the ultra-fine powder was enhanced by 18.31% compared with the cribble by the chromatograph analysis of icariin. At the same time, Astragalus membranaceus polysaccharide and Epimedium brevicornum polysaccharide content of the ultra-fine powder were enhanced by 117.13% and 315.15% compared with the cribble.
