A Lagrangian formulation of perfect fluid is a powerful tool to study the dynamics of the universe, especially interacting approach between dark energy and dark matter. A general description in this formulation is complicated and then it is difficult to handle since it invokes many functions. In field theory point of view, a non-canonical scalar field can be used to describe the perfect fluid with constant equation of state parameter. However, it cannot provide a consistent description since it cannot provide the intrinsic vector perturbations to the theory as well as non-adiabatic perturbations. In this presentation, the Lagrangian formulation of perfect fluid due to the non-canonical three-form field is proposed. It is found that the perfect fluid with constant equation of state parameter can be realized by using this three-form field. The fluid dynamics of the perfect fluid is investigated and found that the non-adiabatic perturbations can be generated and thermodynamics description of the theory corresponds to the system in which the particle flux is not conserved.
