Fagopyrin is a term used for several closely related naturally occurring substances in the buckwheat plant.[1]
Their chemical structure contains a naphthodianthrone skeleton similar to that of hypericin.[2]
Fagopyrin is located almost exclusively in the cotyledons of the buckwheat herb. When ingested, fagopyrins cause sensitivity to light.[3]
