In this paper, we have studied the generalized chaplygin gas of interacting dark energy to ob-tain the equation of state for the generalized chaplygin gas energy density in anisotropic Bianchi type-I cosmological model. For negative value of B in equation of state of generalized chaplygin gas, we see that γ effΛ<-1 , that corresponds to a universe dominated by phantom dark energy.
