6',7'-Dihydroxybergamottin

6',7'-Dihydroxybergamottin is a natural furanocoumarin found in pomelos, grapefruits, and sour oranges,^[1] in both the peel and the pulp. Along with the chemically related compound bergamottin, it is believed to be responsible for a number of grapefruit–drug interactions, in which the consumption of citrus containing one or both of these compounds (especially grapefruit) affects the metabolism of a variety of pharmaceutical drugs.^[2][3][4]
