Using the q-derivative operator in conjunction with the principle of subordination between analytic functions, we introduce two subclasses of analytic functions in the open unit disk U. We investigate convolution properties and coefficient estimates for these subclasses. Mathematics Subject Classification (2010): 30C45, 30C50. Keywords: Analytic functions, univalent functions, Hadamard product (or convolution), subordination between analytic functions, q-derivative operator.which are analytic in U. Also S be the subclass of all functions in A, which are univalent in U. Let S * (α) and K(α) denote the subclasses of S consisting of starlike and convex functions of order α (0 α < 1). We note that
