In the minimal supersymmetric standard model (MSSM), when radiative corrections are included, the mass of the [ital CP]=+1 lightest Higgs boson is bounded by [similar to]110 GeV for [ital m][sub [ital t]][lt]150 GeV and a scale of supersymmetry breaking [similar to]1 TeV. In non-minimal supersymmetric standard models (NMSSM) upper bounds on the mass of the corresponding scalar Higgs boson arise if the theory is required to remain perturbative up to scales [much gt][ital G][sup [minus]1/2][sub [ital F]]. We have computed those bounds for two illustrative NMSSM: (i) A model with an arbitrary number of gauge singlets; (ii) A model with three [ital SU](2)[sub [ital L]] triplets with [ital Y]=0, [plus minus]1. We have integrated numerically the corresponding renormalization group equations (RGE), including the top and bottom quark Yukawa couplings, and added one-loop radiative corrections. For [ital m][sub [ital t]][gt]91 GeV the absolute bounds are [similar to]140 GeV for both models.
