AbstractThe chiral effective Lagrangian for pseudoscalar meson nonet including eight Goldstone bosons and a SU(3) singlet eta 0 is constructed with the breaking effect of chiral symmetry in both quark condensate and quark mass differences taken into account. The pi(0)-eta-eta' mixing is discussed. By solving the mass equations of pseudoscalar mesons, the quark mass ratios are obtained and the quark condensate ratios are constrained in ranges. The mass split of pi(0) - pi(+/-) is discussed.
