This paper is concerned with the estimate of second Hankel determinant for the classes of analytic functions whose derivative has a positive real part, analytic functions with respect to conjugate points and with respect to symmetric conjugate points in the unit disc U = {z : |z| < 1}. AMS Subject Classification: 30C45 Key Words: analytic functions, starlike functions, convex functions, functions whose derivative has a positive real part, starlike functions with respect to conjugate points,
