Pterostilbene () (trans-3,5-dimethoxy-4-hydroxystilbene) is a stilbenoid chemically related to resveratrol. In plants, it serves a defensive phytoalexin role.
== Natural occurrence == Pterostilbene is found in almonds, various Vaccinium berries (including blueberries), grape leaves and vines. It is also encountered in the xylem, particularly in the heartwood of Pterocarpus marsupium as well as in other species of the Pterocarpus family, including Malay padauk, the Narra tree (Pterocarpus indicus), Muninga and African padauk (Pterocarpus erinaceus), thus contributing to the high natural durability as a known phytoalexin.
