We investigate the entanglement measures of tripartite W-State and GHZ-state in noninertial frame through the coordinate transformation between Minkowski and Rindler. First it is shown that all three qubits undergo in a uniform acceleration a of W-State, we find that the one-tangle, two-tangle, and π-tangle decrease when the acceleration parameter r increases, and the two-tangle cannot arrive to infinity of the acceleration. Next we show that the one qubit goes in a uniform acceleration a1 and the other two undergo in a uniform acceleration a of GHZ-state, we find that the two-tangle is equal to zero and NBI (AI CI) = NCI (AI BI)≠ NAI (BI CI), but one-tangle and π-tangle never reduce to zero for any acceleration.
