                         the Universe is quintessence dynamics. The basic idea of 
                         quintessence consists of analyzing cosmological scenarios driven 
                         by scalar fields. In this work we present some interesting 
                         features on the cosmological scenario obtained from the solutions 
                         of an effective two scalar field model in a flat space-time. This 
                         effective model was constructed by coupling two single scalar 
                         field systems in a nontrivial way via an extension method. The 
                         solutions related to the fields allowed us to compute analytical 
                         cosmological parameters. The behavior of these parameters are 
                         highlighted, as well as the different epochs obtained from them.",
