Аннотация:One of the important sources for independentdetermination of stellar masses is eclipsing binaries with components on the main sequence, and with observable spectral lines of both components. The parameters of such stars are used to construct the mass–luminosityrelation for stars of high and intermediate masses. Among them, the type of long-period eclipsing binaries stands out, the parameters of which are currently not fully determined,which is associated with the difficulties caused by the need forlong-termobservations.Inthisarticle,wewillreviewthecurrently available observational data for such objects and discuss the prospects for their use to determine stellar masses
