We present results about the distribution and kinematics of the
molecular environment of
the AGN in NGC 1068, over a 
region around the central
engine in NGC 1068, derived from H2 line emission detected with
ISAAC at VLT/ANTU on ESO/Paranal. The H2 emitting molecular gas
is found to be distributed along the East-West direction and with two
main peak emission (knots) located at a distance of about 70 pc from the
central engine. The eastern H2 knot is more intense than
the western one.
The line profiles mapped across the entire region, at a
spatial resolution of 
,
appear to be quite complex with either a blue or red wing. At first order,
we find a velocity difference of
140 km s-1 between
the two knots; if interpreted as quasi-Keplerian velocity, this
implies a central enclosed mass of 
.
