ABSTRACT
Objective To study the influence of mill speed on extract of ultra- fine powder of Bulbus Fritillariae Cirrhosae. Methods The extraction rate of ultra- fine powder of Bulbus Fritillariae Cirrhosae, which passed a 400- mesh screen, was detected and compared with that passed a 100- mesh screen under different mill speeds. At the same time, mathematical models for extraction established with applied hyperbolic function and Weibuer function were compared. Result The extraction rate of the ultra- fine powder was higher than that of the fine powder when the mill speed was over 70 r/min (P 0.05). Applied hyperbolic function was superior to Weibuer function for the simulation of extraction. Conclusion The mill speed has an influence on the extraction of to ultra- fine powder of Bulbus Fritillariae Cirrhosae, indicating that the effect of divergent function on the extraction should be considered.
