This paper deals with the existence of 
-quasi-solutions for impulsive periodic boundary value problems in an ordered Banach
space 
. Under a new concept of upper and lower solutions, a new monotone iterative technique
on periodic boundary value problems of impulsive differential equations has been established.
Our result improves and extends some relevant results in abstract differential equations.
