The combined effects of heat and mass transfer on unsteady magnetohydrodynamic (MHD) free convection flow in a porous medium past an infinite inclined plate with ramped wall temperature have been investigated. The closed form analytical solutions have been obtained for the velocity, temperature and concentration fields by using Laplace transforms method. The analytical expressions for non-dimensional skin-friction, Nusselt number and Sherwood number have been computed. The effects of the embedded flow parameters such as inclination angle, radiation parameter, magnetic field parameter, and Grash of number on flow fields are shown graphically. It is found that increasing the inclination angle and radiation parameters, the fluid velocity along an inclined plate will be decreased.
