Inclusive semileptonic B decays offer a possibility to test the Standard Model (SM) in its flavor structure. The relevant SM parameters are the quark mixing parameters that accompany these types of decays, gathered in the CKM matrix. In my talk I'm going to present the technique to determine the inclusive width of a heavy flavored meson which allow to extract the CKM matrix elements $V_{qb}$. As an approach we use the Heavy quark expansion and calculate analytically the perturbative QCD corrections to the power suppressed contribution of the chromo-magnetic operator. In the calculation the final state quark is treated as massless.
