Annotation

Perturbations of the inner orbit of the multiple stellar system $\xi U.Ma.$ are calculated usirig formulas derived in previously published papers. Secular changes in the elements $e_1$, $\Omega_1$ and $I_1$ are reported. The results show that the perturbations of the inner orbit are substantial and must be taken into account.
