%X Perturbative Post-Newtonian variations of the standard osculating orbital elements are obtained by using the two-body equations of motion in the Parameterized Post-Newtonian theoretical framework. The results obtained are applied to the Einstein and. Brans - Dicke theories. As a results, the semi-major axis and eccentricity exhibit periodic variation, but no secular changes.. The longitude of periastron and mean longitude at epoch experience both secular and periodic shifts. The Post-Newtonian effects are calculated and discussed for six extrasolar planets.
