%X The study aimed to determine the preparation process of micron particles of Asarum, and to investigate impact on volatile components during the process of ultra-fine pulverization. The particle size distribution value of Asarum was defined as D90 and D50. The best time of Asarum pulverization was preliminary screened. Capillary gas chromatography was used to compare the methyleugenol and safrole content of Asarum powders of different sizes. Infrared spectrometry was applied to determine the chemical composition change of Asarum before and after pulverization. Results show that vibration mill grinding is able to break the cell wall, and yet cause no loss of volatile components in Asarum at low temperature. Content of methyleugenol reaches to the highest level at 6 minutes during vibration grinding process, but the content of safrole reaches to the highest level at 12 minutes. No chemical composition change of Asarum had been detected after ultra-fine pulverization. Preliminary study proved that ultra-fine pulverization techniques can be used for Asarum powder preparation.
