  In this work we study class I interior solutions supported by anisotropic
polytropes. The generalized Lane--Emden equation compatible with the embedding
condition is obtained and solved for a different set of parameters in both the
isothermal and non--isothermal regimes. For completeness, the Tolman mass is
computed and analysed to some extend. As a complementary study we consider the
impact of the Karmarkar condition on the mass and the Tolman mass functions
respectively. Comparison with other results in literature are discussed.
