We give an estimation of the masses of light dark matter particle and dark energy quasiparticle which can be extracted from the astrophysical data about the contributions of baryon, dark matter, and dark energy densities to the total matter-energy density budget in our universe. We use the quantum cosmological model in which dark energy is a condensate of quantum oscillations of primordial scalar field. The dark energy quasiparticle with the mass ~ 15 GeV is consistent with the 7-year WMAP and other data. The quasiparticles can decay with violation of CP-invariance into baryons, leptons, and dark matter. The WIMP mass ~ 5 GeV corresponds to observed values of baryon and dark matter energy densities. Such a mass agrees with the observations of CoGeNT, DAMA, and CDMS. Quasiparticles of dark energy can be registered as a constant background of radiation with the frequency ~ 3.64 x 10^{24} 1/s. Dark matter particles must exhibit themselves in the form of signals with the frequency ~ 1.21 x 10^{24} 1/s of radiation from galaxy clusters where the intensive gravitational fields produced by dark matter exist.
