  A variation of Affleck-Dine mechanism was proposed to generate the observed
baryon asymmetry in [1], in which the inflaton was assumed to be a complex
scalar field with a weakly broken $U(1)$ symmetry, and the baryon asymmetry
generation was easily unified with the stage of inflation and reheating. We
adapt this mechanism to natural inflation scenarios and compare the results
with those in chaotic inflation models. We compute the net particle number
obtained at the end of inflation and transform it into net baryon number after
reheatings. We observed that in natural inflation models, the desired
baryon-to-photon ratio can be achieved equally well as in chaotic models.
