In the three-state mixing framework, considering the possible glueball components of eta and eta we investigate the hadronic decays of f(o)(1370), f(o)(1500) and f(o)(1710) into two pseudoscalar mesons. The quarkonia-glueball content of the three states is: determined from a fit to the new data presented by the WA102 Collaboration. The find that these data are insensitive to the possible glueball components of eta and eta Furthermore. we discuss some properties of the mass matrix describing the mixing of the isoscalar scalar mesons.
