Abstract: The components of traditional Chinese medicine calamine were determined with thermogravimetric analysis method and otherwise. Nanosized zinc carbonate alkali and nanosized zinc oxide were synthesized, and nanosized calamine was prepared. The particle size and morphology of calamine, zinc carbonate alkali and zinc oxide were determined by laser size analysis device and transmission electron microscope(TEM). The antibacterial activity of calamine and its components were determined by using beaker disc method. The result shows that the antibacterial activity of calamine was decided by the content and particle size of zinc oxide, and the antibacterial activity of nanosized calamine was better than that of calamine. Nanosized calamine possesses the characters of calamine and nanosized traditional Chinese medicine, and it has the double activities of calamine and nanoparticles. Zinc carbonate alkali and nanosized zinc carbonate alkali have not antibacterial activity for the four bacteria in this paper.

Key words: Nanosized calamine, Zinc carbonate alkali, Zinc oxide, Antibacterial activity
