We present the results of long-slit observations of the sample of kinematically confirmed polar-ring galaxies from SPRC catalogue performed at 6-m SAO RAS telescope. The aim of our study was the detection and analysis of the gas emission in both main and polar discs of the galaxies together with their stellar population parameters in order to improve the 'luminosity-metallicity' statistical relation. We estimated the gas chemical abundance for 15 SPRC galaxies. The metallicities obtained are almost the same for main and polar components that rules out the cold accretion scenario for the considered polar structures
