Based on the general relativistic theory, an investigation on the polytropic fluid spheres with negative index is made. The difference between classical gravitational theory and the relativistic one is measured by a parameter σ, which is the ratio of pressure to density at the center of the sphere. The relativistic Emden functions for ned* increases with the value of σ.
