Four H II regions of the Sd galaxy NGC 7793 were observed using AAT/IPCS. From these spectra the author determines abundances of the elements using observed emission lines and electron temperatures. The calculated abundances show that this galaxy does not show any significant radial abundance gradient. The mean oxygen abundance is very much like the Orion nebula and the nitrogen abundance is similar to the late type barred spiral galaxy NGC 1313.
