Pterostilbene is a stilbenoid chemically related to resveratrol. In plants, it serves a defensive phytoalexin role.[1]

Natural occurrences[edit]

Pterostilbene is found in almonds,[2] various Vaccinium berries[3] and grape leaves and vines.[1][4]

While resveratrol is under research for its potential properties from consuming wine and other foods or beverages, pterostilbene is not found in wine.[5]

Basic research[edit]

The possible biological effects of pterostilbene are being examined in basic research involving laboratory models of several disorders, including age-related cognitive decline.[6]
