Following the earlier studies on embedded unitary ensembles generated byrandom two-body interactions [EGUE(2)] with spin SU(2) and spin-isospin SU(4)symmetries, developed is a general formulation, for deriving lower ordermoments of the one- and two-point correlation functions in eigenvalues, that isvalid for any EGUE(2) and BEGUE(2) ('B' stands for bosons) with $U(\Omega)\otimes SU(r)$ embedding and with two-body interactions preserving $SU(r)$symmetry. Using this formulation with $r=1$, we recover the results derived byAsaga et al [Ann. Phys. (N.Y.) 297, 344 (2002)] for spinless boson systems.Going further, new results are obtained for $r=2$ (this corresponds to twospecies boson systems) and $r=3$ (this corresponds to spin 1 boson systems).
