Abstract: The present paper proves the following result : Let R be a 2-torsion free prime ring, let J be a Jordan ideal and a subring of R. If φ: R→R is an automorphism satisfying φ(u2)=φ(u)2 for all u∈J, then φ(uv)=φ(u)φ(v) or φ(uv)=φ(v)φ(u) f or all u,v∈J.

Key words: prime ring, Jordan ideal, torsion free ring, homomorphism, Jordan homomorphism, Jordan automorphism
