Abstract
We establish the connection between the structural coupling constants of the phenomenological chiral lagrangian and the coefficients of effe ctive lagrangians obtained in the QCD-bosonization models by means of the derivative expansion. The extension of the chiral lagrangian descr ibing matrix elements of the pseudoscalar gluon density is examined. T he large-N(c) relations for corresponding structural constants are ela borated.
