  This work presents timing and spectral analysis of 4U 2206+54 using data
obtained from LAXPC instrument onboard India's AstroSat mission. This source
was observed with AstroSat in September 2016 and October 2016. We report
detection of $5648 (4)$ s pulsations at MJD 57669 in the latter observation of
4U 2206+54. The pulse profile is sinusoidal and the inherent shape is
independent of energy up to 30 keV. The pulse fraction increases with energy
from $\sim 0.5$% to $\sim 0.8$%. We report an updated spin down rate of $2.95
(14) \times 10^{-7}$ s s$^{-1}$. This is about 0.40 times smaller than the
previously reported long term value. The energy spectrum is best modelled with
an absorbed power-law with high energy exponential cut-off. We have detected
presence of broad emission line in 4U 2206+54 at an energy of $7$ keV with
equivalent width of $\sim 0.4$ keV.
