Unusual constituent quark axial current couplings to light vector mesons,$\rho$ and $\omega$, are derived in the vacuum and under weak magnetic field byconsidering a quark-antiquark interaction mediated by a non perturbative gluonexchange. Similarly, light axial mesons are found to couple anomalously withthe constituent quark vector current. These interactions are of the type of theWess-Zumino-Witten terms, being strongly anisotropic and dependent on thevector (or axial) meson polarization. They also provide axial (vector) formfactors for the vector (axial) mesons and are quite small, suppressed nearly by$1/{M^*}^2$ with respect to the vector mesons minimal coupling to the quarkvector current. Some three leg meson vertices are also presented:$\pi-\rho-A_1$ and $V_1V_2 A$ (where $V_1,V_2$ are vector mesons and $A$ anaxial meson). A vector and axial-vector mesons mixing is identified at non zeromagnetic field which however can contribute only in the presence of a thirdparticle or in a medium. Numerical results are presented for differenteffective gluon propagators.
