Estimating the black hole mass at the center of galaxies is a fundamental step for understanding not only the physics of accretion but also the cosmological evolution. Recently, a new method to estimate the black hole mass in Galactic systems, based on X-ray spectral data, was successfully applied to several X-ray binaries. Since the mechanism producing the X-rays is thought to be the same in stellar and supermassive black holes, in principle, the same method can be applied to estimate the mass in supermassive black holes. Here we present the preliminary results of study where this method is applied to a sample of AGN, which possess good XMM-Newton archival data and whose black hole mass has been already determined via reverberation mapping.
