  We study inflation in scalar-tensor perturbative quantum gravity driven by a
one-loop effective potential. We consider effective potentials generated by
three models. The first model describes a single scalar field with a
non-vanishing mass. The second model describes a massless scalar field with
non-minimal coupling to the Einstein tensor. The third model generalises the
Coleman-Weinberg model for the gravitational case. The first model can be
consistent with the observational data for $N\sim 70$ e-foldings. The second
model can be consistent with the observational data for $N \sim 40$ e-foldings.
We did not find parameters that make the generalised Coleman-Weinberg model
consistent with the observational data. We discuss the implications of these
results and ways to improve them with other terms of effective action.
