We show that Jensen measures defined on C n or more generally on a complex Banach space X can be approximated by the image of Lebesgue measure on the torus under X-valued polynomials defined on C. We give similar characterizations for Jensen measures in terms of analytic martingales and Hardy martingales. The results are applied to approximate plurisubharmonic martingales by Hardy martingales, which enables us to give a characterization of the analytic Radon-Nikodym property of Banach spaces in terms of convergence of plurisubharmonic martingales, thus solving a problem of G.
