We use a consistent SU(6) extension of the mesonbaryon chiral Lagrangian within a coupled channel unitary approach in order to calculate the Tmatrix for mesonbaryon scattering in swave. The building blocks of the scheme are the pion and nucleon octets, the rho nonet and the Delta decuplet. We identify poles in this unitary Tmatrix and interpret them as resonances. We study here the non exotic sectors with strangeness S=0,1,2,3 and spin J=1/2, 3/2 and 5/2. Many of the poles generated can be associated with known N, Delta, Sigma, Lambda and Xi resonances with negative parity. We show that most of the lowlying three and four star odd parity baryon resonances with spin 1/2 and 3/2 can be related to multiplets of the spinflavor symmetry group SU(6). This study allows us to predict the spinparity of the Xi(1620), Xi(1690), Xi(1950), Xi(2250), Omega(2250) and Omega(2380) resonances, which have not been determined experimentally yet.
