Abstract

An aqueous phase sonication technique method was developed for the rapid preparation of four kinds of Chinese herbs (Licorice, Tuckahoe, Rhizoma Atractylodis Macrocephalae and Ginseng) nanoparticles. The nanoparticles were characterized by the laser particles size analyzer, infrared spectroscopy and scanning electron micrograph. The particle size of 95% nanoparticles was nearly 200nm. Moreover, the nanoparticles had very similar chemical composition with primary particles, despite slight changes. Therefore, this preparation technique was demonstrated to be a simple, available and effective method to get high quality nanoparticles of Chinese herbs.
