In this paper, various coefficient bounds of functions in some classes which are defined by subordination are estimated. Some special consequences of the main results are also presented. Moreover, it is pointed out that the given bounds improve and generalize some of the pervious results.

Keywords: Univalent functions, coefficient bounds, starlike functions, subordination
