We present preliminary results obtained by spectroscopic and photometric observations of the previously not studied eclipsing binary V1385 Ori. Spectroscopic observations were performed with the Poznań Spectroscopic Telescope (PST). Photometric data used in the following work were taken from All Sky Automated Survey (ASAS). We have collected spectroscopic data to cover most of phases of the orbital motion. Data reduction was performed with the IRAF package. In order to determine radial velocities of components, one-dimensional cross-correlation technique has been used. The results of the orbital solution from radial velocity curves are combined with those derived from the light curve analysis to calculate orbital and stellar parameters. PHOEBE - a code based on Wilson-Devinney binary modelling method was applied for that analysis. As a result we determined the absolute parameters: mass, radius and temperature as well as the age and distance to the system.
