We theoretically investigate and characterize properties of a weakly interacting

$^{23}$Na  Bose gas confined in anisotropic potential. The analytical expressions for condensed fraction , average energy per particle and effective width are derived. Some characteristics of confined interacting Bose gases are revealed. The obtained results of condensed fraction is compared with the experimental data for $^{23}$Na directly, it shows excellent agreement while the other two parameters are compared to hypothetical experiment.
