Abstract:	We present the results of high-angular-resolution in 3-mm and 0.8-mm band observations with ALMA in cycle-0 toward one of the nearest galaxies with an active galactic nucleus (AGN), NGC 1068. The physical properties of CO isotopic species, CS, CN, and shock and dust related molecules such as HNCO, CH₃CN, SO, and CH₃OH were estimated using rotation diagrams. We discuss the chemistry of each species, and compare the fractional abundances in the circumnuclear disk (CND) and starburst ring with those of Galactic sources in order to study the overall characteristics.
