ABSTRACT
Objective To compare the micromeritics properties and external dissolution rates of Sanhuang Powder in different particle sizes;To provide references for its direct use and application as raw materials for TCM preparation.Methods Particle size, bulk density, tap density, angle of repose, and hygroscopicity ofSanhuang micro-powder and common powder were investigated and evaluated. External dissolution rates ofSanhuang micro-powder and common powder were detected by ultraviolet spectrophotometry.Results The flowability of bothSanhuang micro-powder and common powder were not very well. With the sizes decreasing, the hygroscopicity of micro-powder became stronger. The external dissolution ofSanhuang micro-powder was more sufficient and much more quickly than common powder.Conclusion Properties ofSanhuang micro-powder and common powder are obviously different.Sanhuang micro-powder has stronger hygroscopicity and worse flowability compared with common powder. However, external dissolution ofSanhuang micro-powder is more sufficient and much more quickly than common powder. WhenSanhuang micro-powder is used directly and used as raw materials for TCM preparation, much more discretion should be considered.
