Hadronic resonances can play a pivotal role in providing experimental evidence for partial chiral symmetry restoration in the deconfined quark-gluon phase produced in high energy nucleus-nucleus collisions at RHIC and LHC. Their short lifetimes, when comparable to the lifetime of the fireball, make them a valuable tool to study medium modifications to the resonant state due to the chiral phase transition signatures of mass shifts and/or width broadenings. This can be done via the leptonic decay of resonances having relatively small interaction cross-section of leptonic daughter particles with dense hadronic medium. The measurement of $\phi \rightarrow e^{+}e^{-}$ at mid-rapidity ($|y|<1$) from STAR experiment in Au+Au collisions at $\sqrt{s_{_{NN}}}$ = 200 GeV are presented and compared to the $\phi$ meson result from the hadronic decay channel.
