The gas fueling (triggering mechanism) into the supermassive black hole (SMBH) of active galactic nuclei (AGNs) seems to regulate the nuclear star formation activity. This relation, called as AGN-starburst connection, has been investigated through several studies (e.g. Norman & Scoville 1988; Storchi-Bergmann et al. 2000, 2001; Kauffmann et al. 2007; Diamond-Stanic & Rieke 2012; LaMassa et al. 2013).

We derive the nitrogen and oxygen abundances in the Narrow Line Regions (NLRs) of a sample of 38 local (z 5) show N/O values in consonance with those derived for local NLRs. This result indicates that the main star-formation event is completed in the early evolution stages of active galaxies.
