[en] During the commissioning phase of the International Ultraviolet Explorer several extragalactic objects were observed spectrally at low dispersion in the UV range lambdalambda1150-3200: the Seyfert galaxies NGC4151 and NGC1068, the QSO 3C273, the BL Lacertae object B2 1101 + 38, the giant eliptical galaxy M87 and the spiral galaxy M81. The results obtained are presented and a preliminary analysis given for all six objects, discussing the continuous spectrum, extinction, emission line spectrum and absorption line spectrum, where possible for each case. Several new or confirmatory astrophysical results are obtained. (author)
