The results of QCD analysis of a set of a fake' data on the $\Delta q_3(x,Q^2)$, $\Delta q_8(x,Q^2)$ and $D^{\pi^{+}}_{u_v}(z,Q^2)$ based on the analytic approach called the analytic perturbation theory (APT) are presented. The fake' data were constructed based on parametrization of polarized PDFand nonsinglet combination of the pion fragmentation functions.
