We investigate the large scale cosmological perturbation in the Universe with
multiple perfect fluids. Using the long-wavelength approximation with
Hamilton-Jacobi method, we derive the formula for the gauge invariant comoving
curvature perturbation. As an application of our approach, we examine the large
scale perturbation in a brane cosmology.
