Piceatannol is the organic compound with the formula ((HO)
2C
6H
3)
2CH)
2. Classified as a stilbenoid and a phenol, it is a white solid, although samples often are yellow owing to impurities.
Natural occurrences
Piceatannol and its glucoside, astringin, are found in mycorrhizal and non-mycorrhizal roots of Norway spruces (Picea abies).[1] It can also be found in the seeds of the palm Aiphanes horrida[2] and in Gnetum cleistostachyum.[3] The chemical structure of piceatannol was established by Cunningham et al. as being an analog of resveratrol.[4]
In food
Piceatannol is a metabolite of resveratrol found in red wine, grapes, passion fruit, white tea, and Japanese knotweed.[5] Astringin, a piceatannol glucoside, is also found in red wine. The formation of piceatannol from resveratrol is catalyzed by cytochrome P450.[6]
Biochemical study
A 1989 in vitro study found that piceatannol blocked LMP2A, a viral protein-tyrosine kinase implicated in leukemia, non-Hodgkin's lymphoma and other diseases associated with Epstein–Barr virus.[7] In 2003, this prompted research interest in piceatannol and its effect on these diseases.[8]
Injected in rats, piceatannol shows a rapid glucuronidation and a poor bioavailability, according to a 2006 study.[9]
Piceatannol affect gene expressions, gene functions and insulin action, resulting in the delay or complete inhibition of adipogenesis.[10][11]
Passion fruit seeds are rich in piceatannol and scirpusin B (dimer of piceatannol) as polyphenols, both of which have been reported to have vasodilating effects in the thoracic aorta and coronary artery of rats.[12] Furthermore, these polyphenols did not increase heart rate (i.e., these polyphenols did not increase oxygen consumption), suggesting that piceatannol and scirpusin B may have protective effects on ischemic heart disease.
