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]

Prunetin can lower blood pressure of spontaneously hypertensive rats and relax isolated rat aortic rings through calcium channel block mechanisms in vessel smooth muscles.^[4]

Glycosides

8-C-glucosyl prunetin, isolated from the leaves of Dalbergia hainanensis^[5]
