Given a positive integer n, a finite group G is called quasi-core-n if
has order at most n for any element x in G, where is the normal core of in G. In this paper, we investigate the structure of finite quasi-core-p p-groups. We prove that if the nilpotency class of a quasi-core-p p-group is , then the exponent of its commutator subgroup cannot exceed , where p is an odd prime and m is non-negative. If , we prove that every quasi-core-3 3-group has nilpotency class at most 5 and its commutator subgroup is of exponent at most 9. We also show that the Frattini subgroup of a quasi-core-2 2-group is abelian.
