Abstract
The low-energy theorem, derived by Terent'ev within the framework of c urrent algebra, is proved at the quark level within the framework of t he Extended Nambu-Jona-Lasinio model. The proposed method allows to ev aluate a vacuum expectation value of any time-ordered product of QCD-h adronic currents in terms of constituent-quark loops and low-lying mes on exchanges.
