The flavor symmetry aspect of the hyperon-nucleon interaction is investigated in a quark model in which the (qq^^-) excitations inherent in the quark-gluon interaction are explicitly incorporated into the model space. It is shown that the long range part of the hyperonnucleon interaction generated from the (3q)-(3q) to (3q)-(3q)(qq^^-) coupling kernels has similar fiavor dependence to that of the SU_3 OBEP, where the SU_3 parameters of the coupling constants are usually selected around the SU_6 values. The flavor-SU_3 symmetry breaking effect is also discussed in the single baryon problem ; results are given for the baryon-meson coupling constants, the ground state baryon spectrum, and the magnetic moments of the octet baryons.
