The {\pi}-tangle is used to study the behavior of entanglement of anonmaximal tripartite state of both Dirac and scalar fields in acceleratedframe. For Dirac fields, the degree of degradation with acceleration of bothone-tangle of accelerated observer and {\pi}-tangle, for the same initialentanglement, is different by just interchanging the values of probabilityamplitudes. A fraction of both one-tangles and the {\pi}-tangle always survivesfor any choice of acceleration and the degree of initial entanglement. Forscalar field, the one-tangle of accelerated observer depends on the choice ofvalues of probability amplitudes and it vanishes in the range of infiniteacceleration, whereas for {\pi}-tangle this is not always true. The dependenceof {\pi}-tangle on probability amplitudes varies with acceleration. In thelower range of acceleration, its behavior changes by switching between thevalues of probability amplitudes and for larger values of acceleration thisdependence on probability amplitudes vanishes. Interestingly, unlike bipartiteentanglement, the degradation of {\pi}-tangle against acceleration in the caseof scalar fields is slower than for Dirac fields.
