In the simplest extension of the Standard Model (SM), known as the Two Higgs Doublet Model (2HDM), a second doublet of scalar fields and a new potential are introduced, the last one depends on seven parameters that determine the masses of the five Higgs bosons that are predicted by the model. We use the one loop renormalization group equations (RGE) to study the mass spectrum of the five particles. The study was conducted in a electroweak unification of Yukawa couplings scenario, with the purpose of reducing the number of parameters of the model and to determine the influence of this consideration in the development of the RGE. The objective of this study is to analytically evaluate the bounds on the quartic couplings and numerically evaluate the energy dependence of the particles masses.
