Works for me on Version 7.0.1. Suppressing the rather long answer:
f[z_] := 5/
12 (-1 + z) (y^2 - 3 z^2) (27 y^4 - 12 Sqrt[3] y^5 + 4 y^6 +
18 y^2 (3 - 2 z) z^2 + 3 (3 - 2 z)^2 z^4 +
4 Sqrt[3] y^3 z^2 (-3 + 2 z));
intgf[z_] = Integrate[f[z], z];
intgf'[z] == f[z] // Simplify
True

Can somebody try this in your version of Mathematica ?
Integrate[(5/12) (-1 + z) (y^2 - 3 z^2) (27 y^4 - 12 Sqrt[3] y^5 +
4 y^6 + 18 y^2 (3 - 2 z) z^2 + 3 (3 - 2 z)^2 z^4 +
4 Sqrt[3] y^3 z^2 (-3 + 2 z)), z]
Something is definitely wrong with my version of Mathematica (7).
