We performed long-slit spectral observations of two SB-type galaxies: NGC5347, UGC 1344. They were previously suspected as the galaxies with unusuallylow mass-to-light ratios (on the ground of mass estimates from the Hilinewidths), which are in conflict with their observed colours. Theobservations were conducted at the Russian 6-m telescope. The aim of the studywas to clarify the kinematics and structure, as well as the properties ofstellar populations of the galaxies. The results of observations disproved thepeculiarly low mass-to-light ratios of both galaxies. The most probable reasonsof underestimation of their masses are discussed. We tried to reproduce themain observed features of kinematical profiles of the galaxies in the N-bodysimulations of barred galaxies. We found that both galaxies possess centralcomponents of different structure. Indeed, the age and velocity dispersion ofstellar population in NGC 5347 are low in its innermost part in comparison tothat of the bulge or a bar, which agrees with the presence of nuclearkinematically decoupled disc. It probably was formed due to the bar whichsupplied the inner region with gas. The kinematical profiles of the secondgalaxy UGC 1344 give evidences in favour of the central peanut-shaped bulge. Inspite of the different luminosities of the two galaxies, they possess nearlyequal (close to solar) central stellar abundance and the flattening of thestellar metallicity gradient in the bar regions. However, in the less luminousNGC 5347 the mean stellar age is younger than that in UGC 1344.
