Grapefruit is an excellent source of flavonoid, a plant material that serves as an antioxidant and anti-inflammatory agent. Grapefruit juice contains the flavonoids naringenin, quercetin, and kaempferol. Naringenin appears to interfere with liver enzymes that facilitate the metabolism of certain drugs, including calcium channel blockers.

The flavonoid that contributes most of the bitter taste of grapefruit is called naringin.
