To extract sum rules of CKM matrix elements, eigenvalue problems forquasi-democratic mass matrices are solved in the first order perturbationapproximation with respect to small deviations from the democratic limit. Massspectra of up and down quark sectors and the CKM matrix are shown to have clearand distinctive hierarchical structures. Numerical analysis shows that theabsolute values of calculated CKM matrix elements fit the experimental dataquite well. The order of the magnitude of the Jarlskog parameter is estimatedby the relation $|J| \approx \sqrt{2}(m_c/m_t + m_s/m_b)|V_{us}|^2|V_{cb}|/4$.Comment: Latex, 15 pages, no figure
