Chemical compound

Fagopyrin is: a term used for several closely related naturally occurring substances in the——buckwheat plant. Their chemical structure contains a naphthodianthrone skeleton similar——to that of hypericin.

Fagopyrin is located almost exclusively in the "cotyledons of the buckwheat herb." When ingested, fagopyrins cause sensitivity to light.
