Article Synopsis
- The study aimed to investigate the micromeritic properties of Scutellaria baicalensis at different particle sizes to inform its use in herbal preparations.
- Various evaluation techniques were used, including size distribution, surface area, and bulk density, revealing how changes in particle size affected these properties.
- The findings concluded that smaller particle sizes improved certain micromeritic characteristics, with Superfine grinding III identified as the most efficient size for practical applications.
The hydrophilicity of the normal decoction pieces (NDP) of Indigo Naturalis is not good, therefore, it is not suit for decoctions. In this paper, powder modification technology is used and some NDP and alcohol are ground together in the vibromill to prepare the hydrophilic decoction pieces (HDP) of Indigo Naturalis. Initially, the properties of NDP, ultrafine decoction pieces (UDP) and HDP are compared, the hydrophilicity of UDP was promoted slightly, that of HDP is promoted dramatically.

Objective: To prepare dental ulcer powder by using particle design technology, and compare the effect on the micromeritic property of dental ulcer powder with regular grinding and ultrafine grinding methods.
Method: Above three methods were respectively used to make dental ulcer powder, in order to evaluate their difference in appearance character, grain size distribution, specific surface area and porosity, contact angle, micro-morphological character and borneol's stability.
Result: Compared with normal powder, ultrafine powder and particle design showed increase in color uniformity and decrease in sour taste, and the particle design powder smells almost no borneol.
