Piceatannol is the organic compound with the formula ((HO)₂C₆H₃)₂CH)₂. It can be classified as a stilbenoid, a phenol, and a polyphenol. It is a white solid, although samples often are yellow owing to impurities. The chemical structure of piceatannol was established as being an analog of resveratrol. ^[1]

Natural occurrences

Piceatannol and its glucoside, astringin, are found in mycorrhizal and non-mycorrhizal roots of Norway spruces (Picea abies). ^[2] It can also be found in the seeds of the palm Aiphanes horrida ^[3] and in Gnetum cleistostachyum . ^[4] Passion fruit seeds are rich in piceatannol and scirpusin B (dimer of piceatannol). ^[5]

In food

Piceatannol is a metabolite of resveratrol found in red wine, grapes, passion fruit, white tea, and Japanese knotweed. ^[6] Astringin, a piceatannol glucoside, is also found in red wine. The formation of piceatannol from resveratrol is catalyzed by cytochrome P450. ^[7]

Biochemistry

Piceattanol acts as an inhibitor of the tyrosine kinase Syk and some related tyrosine kinases. ^[8] In the early 2000s, this prompted research interest in piceatannol and its effect on immune or inflammatory diseases. ^[9]

Injected in rats, piceatannol shows a rapid glucuronidation and a poor bioavailability, according to a 2006 study. ^[10]

Piceatannol affect gene expressions, gene functions and insulin action, resulting in the delay or complete inhibition of adipogenesis. ^{[11] [12]}
