Abstract： The dynamical origin of the mass relations and the interaction between stra-tons inside the hadrons are discussed. Assuming that the wave functions describing the internal structures of the hadrons obey SU(6) symmetry. We rederive the GMO relations and other well-known mass relations. Furthermore, three new relations among the masses of the baryons and the mesons are obtained, namely: (ρ-π)/(K*-K)=(△-N)/(Σ*-Σ), 4(∧-N)=3(K*-ρ)+(K-π), (ρ-π)/(△-N)=((φ-ρ)-2(K-π))/(2(Ω-△)-3/2(K-π)-9/4(φ-ρ)). The connection between these relations and the symmetry properties of the straton interaction is discussed.
