  We present the first result of a comprehensive spectroscopic study of quasar
host galaxies. On-axis, spatially resolved spectra of low redshift quasars have
been obtained with FORS1, mounted on the 8.2m ESO Very Large Telescope, Antu.
The spectra are spatially deconvolved using a spectroscopic version of the
``MCS deconvolution algorithm''. The algorithm decomposes two dimensional
spectra into the individual spectra of the central point-like nucleus and of
its host galaxy. Applied to HE1503+0228, at z=0.135 (M_B=-23.0), it provides us
with the spectrum of the host galaxy between 3600A, and 8500A, (rest-frame), at
a mean resolving power of 700. The data allow us to measure several of the
important Lick indices. The stellar populations and gas ionization state of the
host galaxy of HE1503+0228, are very similar to the ones measured for normal
non-AGN galaxies. Dynamical information is also available for the gas and
stellar components of the galaxy. Using deconvolution and a deprojection
algorithm, velocity curves are derived for emission lines, from the center up
to 4arcsec, away from the nucleus of the galaxy. Fitting a simple
three-components mass model (point mass, spherical halo of dark matter, disk)
to the position-velocity diagram, we infer a mass of M(r<1kpc) = (2.0 +- 0.3)
10^{10} solar mass within the central kiloparsec of the galaxy, and a mass
integrated over 10 kpc of M(r<10kpc) = (1.9 +- 0.3) 10^{11} solar mass, with an
additional 10% error due to the uncertainty on the inclination of the galaxy.
This, in combination with the analysis of the stellar populations indicates
that the host galaxy of HE1503+0228, is a normal spiral galaxy.
