Based on η-η' mixing analysis, we propose a novel method to extract the physical solutions for the hadronic properties of the Y(4230) resonance from the experimental data. Experimentally, multiple solutions have been reported in the decays of Y(4230) → ηJ/ψ and Y(4230) → η' J/ψ. Utilizing our method, we determine a unique solution for the process Y(4230) → η' J/ψ. Likewise, two solutions for the process Y(4230) → ηJ/ψ are preferred among the originally reported three solutions under the assumption that Y(4230) dose not take an ss component.
