Resumen

The oxygen abundances of 18 dwarf spiral galaxies are presented. In most of them, the abundance are determined with semi empirical methods. We find that the values are sub-solar for most of the galaxies, similar to those observed in other late-type galaxies, as BCG or dwarf irregular. The abundance gradient can be determined in four of these galaxies, one of them a barred one. The gradients of the three non-barred galaxies in the sample are larger than-0.15 dex/kpc, while the gradient of the barred galaxy is shallower, only-0.1 dex/kpc.
