Prunetin is an O-methylated isoflavone, a type of flavonoid. It has been isolated for the first time by Finnemore in 1910 in the bark of Prunus emarginata (the Oregon cherry).[1] Prunetin isolated from pea roots can act as an attractant for Aphanomyces euteiches zoospores.[2] It is also an allosteric inhibitor of human liver aldehyde dehydrogenase.[3]

Glycosides

  • 8-C-glucosyl prunetin, isolated from the leaves of Dalbergia hainanensis[4]
