Let \((A,\hspace{0.55542pt}{\cdot }\hspace{1.111pt},\omega )\) be a simple n-Lie Poisson algebra over a field of zero characteristic, \( 1 \in A\) . Then we prove that the n-Lie algebra \(A^{[1]}/(A^{[1]}\cap Z)\) is simple, where \(A^{[1]}\) denotes the derived n-Lie ideal and Z is the center of n-Lie algebra \((A,\omega )\) .
