Nonlinear Relations between QCD Sum Rules for $\eta\Sigma\Sigma$ $\eta\Lambda\Lambda$ and $\pi\Lambda\Sigma$ Coupling Constants.

New relations between QCD Borel sum rules for strong coupling constants are
shown that starting from the sum rules for the coupling constants gM$\Sigma\Sigma$, M = $\pi^0,\eta$ it is straightforward to obtain the corresponding sum rules for the $g\pi\Lambda\Sigma$ and $\eta\Lambda\Lambda$ ones. In the given range of parameters the values of these couplings are obtained.
