Abstract: The physicochemical characteristics of Chrysanthemum morifolium Chuju powders were investigated to increase its utilization value and to develop novel products. Comparing the physicochemical properties between the submicron powder and common powder, the indicators of repose angle, slip angle, solubility, soakage, dispersibility, the images of SEM, and dissolution of main active components were obtained to evaluate the quality of powder products. The repose angle of submicron powder was 36.76º, while that of the common powder was 48.77º, which represents the appreciable flowability of submicron powder. The wetting time of submicron powder was 103s, which was way less than that of common powder (8963s). The SEM micrographs showed that submicron powder had long cracks on its plant cell. The HPLC chromatograms indicated that the dissolution of submicron  powder was higher than that of common powder. The results showed that not only physical but also chemical characteristics of submicron powders were much superior than those of common powders.
