We study a sample of 119 Herbig Ae/Be stars in the Galactic anti-centerdirection using the spectroscopic data from Large sky Area Multi-Object fiberSpectroscopic Telescope (LAMOST) survey program. Emission lines of hydrogenbelonging to the Balmer and Paschen series, and metallic lines of species suchas FeII, OI, CaII triplet are identified. A moderate correlation is observedbetween the emission strengths of H$\alpha$ and FeII 5169 \r{A}, suggesting apossible common emission region for FeII lines and one of the components ofH$\alpha$. We explored a technique for the extinction correction of the HAeBestars using diffuse interstellar bands present in the spectrum. We estimatedthe stellar parameters such as age and mass of these HAeBe stars, which arefound to be in the range 0.1 -- 10 Myr and 1.5 -- 10 $M_{\odot}$, respectively.We found that the mass accretion rate of the HAeBe stars in the Galacticanti-center direction follows the relation $\dot{M}_{acc}$ $\propto$$M_{*}^{3.12^{+0.21}_{-0.34}}$, which is similar to the relation derived forHAeBe stars in other regions of the Galaxy. The mass accretion rate of HAeBestars is found to have a functional form of $\dot{M}_{acc} \propto t^{-1.1 \pm0.2}$ with age, in agreement with previous studies.
