We investigate the strong vertices among Λb, nucleon and B meson as well as Λc, nucleon and D meson in QCD. In particular, we calculate the strong coupling constants gΛbNB and gΛcND for different Dirac structures entered the calculations. In the case of ΛcND vertex, the result is compared with the only existing prediction obtained at Q2=0.
