Prunetin

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]
