We study some restrictions to the unknown vertices of the two Higgs doublet model type
III in the quark sector, by using leptonic decays of the Bd and Bs mesons. In particular,
we find some bounds for the vertices or products of them, that depend on the pseudoscalar
Higgs boson mass (mA). With mA lying at the electroweak scale, we find that E^2_db lies at
the order of 10-3.
