Using the ALMA archival data of both CO(6-5) line and 689 GHz continuum emission towards the archetypical Seyfert galaxy, NGC1068, we identified a distinct dense gas separated by 15pc from the AGN, in projection. The continuum flux gives a gas mass of M_gas 2 x 10^5 Msun and bolometric luminosity of 10^8 Lsun, leading to a star formation rate (SFR) of 0.1 M_sun/yr. We found that the gas stands a unique position between galactic and extraglactic clouds in the diagrams of SFR vs. gas mass. All the properties may be understood in terms of the turbulence-regulated star formation scenario.
