In the inflationary scenario of loop quantum cosmology (LQC) in the presence of inverse-volume corrections, we study the power spectra of scalar and tensor perturbations convenient to confront with observations. Using the recent data of cosmic microwave background (CMB) and other cosmological experiments, for the first time we place experimental bounds on the LQC quantum corrections for several inflaton potentials.
