It is argued that the quark mass difference $m_b-m_c$ can be extracted with a
high accuracy from experimental data on ratia of moments of lepton energy
spectrum in semileptonic decays of $B$ mesons. Theoretical expressions for the
moments are presented, which include perturbative as well as non-perturbative
corrections.
