We present the results of our QCD analysis for polarized quark distribution and structure function xg1(x, Q2). Polarized partem distributions and structure functions of the nucleon are analyzed
in the improved valon model. The Polarized valon distribution in a proton and the polarized partem distributions inside the valon are necessary to obtain the polarized
partem distributions in a proton. Jacobi polynomial method is used to extract the unknown parameters of the polarized valon
distributions by fitting to the available experimental data. The predictions for the NLO calculations of the polarized partem distribution functions are in good agreement with other theoretical models.
