We present results from the study of six low activity galactic nuclei spectra with strong [NII] λλ6548 + 6584 emission lines in order to investigate if this characteristic is due to a peculiar chemical abundance. The selected galaxies NGC1358, NGC1386, NGC4941 and NGC6300 present Seyfert 2 (Sy2) activity, NGC3312 is a LINER and NGC7743 can be classified as intermediate between the two categories. All of them are nearby early type galaxies, whose nucleus present a prominent absorption spectrum with no direct evidence of a non-stellar continuum. Observations were made with the Tololo 1m telescope and 2DFRUTTI detector in the spectral region λλ3700 - 7000 A, with 5A (FWHM) resolution.
