The dynamics of a flat isotropic brane Universe with two-component matter source - perfect fluid with the equation of state p=(gamma-1) rho and a scalar field with a power-law potential V sim phi^{alpha} is investigated. We describe solutions for which the scalar field energy density scales as a power-law of the scale factor. We also describe solutions existing in regions of the parameter space where these scaling solutions are unstable or do not exist.
