We argue the effect of quantum fluctuations on the magnetization process of the quantum frustrated ferromagnets. It is found that on general grounds in the neighborhood of the ferromagnet/antiferromagnet classical 1st-order phase boundary in zero external field, the phase separation or the non-classical phase must appear slightly below the saturation field in the quantum case, if the classical AF is not the eigenstate. Then, we study the ferromagnetic J1-J2 S=1/2 Heisenberg model (J1<0) on the bcc lattice from the viewpoint of the magnon Bose-Einstein condensation. For -1.50097 < J1/J2 < -1.389, the nematic phase is expected and for -1.389 < J1/J2 < -0.48 the phase separation appears under high magnetic field.
