An improved nonlinear equation different from usual and an improved soliton solution of spinor Bose-Einstein condensates(BES)in an optical lattice are obtained by taking into account a nonlinear term in the equation of motion for probability amplitude of spins carefully. The width,peak and energy of soliton are also found.
