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

Natural occurrence

Pterostilbene is found in almonds,[2] various Vaccinium berries,[3] grape leaves and vines [1][4] and blueberries.[5][6]

Research

The possible biological effects of pterostilbene have been examined in basic research involving animal models of several disorders, including age-related cognitive decline, and some clinical trials have been run.[7]

See also

  • Piceatannol, a stilbenoid related to both resveratrol and pterostilbene

Notes

[p] ^ The term "pterostilbene" is pronounced /teh-ro-Still-bean/.[8][9]
