Naringenin is a flavanone, a type of flavonoid. It is the predominant flavanone in grapefruit.[2]

Sources and bioavailability

Naringenin can be found in grapefruit, oranges, and tomatoes (skin).[3]

This bioflavonoid is difficult to absorb on oral ingestion. In the best-case scenario, only 15% of ingested naringenin will get absorbed in the human gastrointestinal tract.

The naringenin-7-glucoside form seems less bioavailable than the aglycol form.[4]

Grapefruit juice can provide much higher plasma concentrations of naringenin than orange juice.[5] Also found in grapefruit is the related compound kaempferol, which has a hydroxyl group next to the ketone group.

Naringenin can be absorbed from cooked tomato paste.[6]

Potential biological effects

Naringenin has been shown to have an inhibitory effect on the human cytochrome P450 isoform CYP1A2, which can change pharmacokinetics in a human (or orthologous) host of several popular drugs in an adverse manner, even resulting in carcinogens of otherwise harmless substances.[7] The National Research Institute of Chinese Medicine in Taiwan conducted experiments on the effects of the grapefruit flavanones naringin and naringenin on CYP450 enzyme expression. Naringenin proved to be a potent inhibitor of the benzo(a)pyrene metabolizing enzyme benzo(a)pyrene hydroxylase (AHH) in experiments in mice.[8]

Naringenin has also been shown to reduce oxidative damage to DNA in vitro and in animal studies.[9]

Naringenin has also been shown to reduce hepatitis C virus production by infected hepatocytes (liver cells) in cell culture. This seems to be secondary to naringenin's ability to inhibit the secretion of very-low-density lipoprotein by the cells.[10] The antiviral effects of naringenin are currently under clinical investigation.[11]

Naringenin seems to protect LDLR-deficient mice from the obesity effects of a high-fat diet.[12]

Naringenin lowers the plasma and hepatic cholesterol concentrations by suppressing HMG-CoA reductase and ACAT in rats fed a high-cholesterol diet.[13]

It also produces BDNF-dependent antidepressant-like effects in mice.[14]

Like many other flavonoids, naringenin has been found to possess weak activity at the opioid receptors.[15] It specifically acts as a non-selective antagonist of all three opioid receptors, albeit with weak affinity.[15]

Metabolism

The enzyme naringenin 8-dimethylallyltransferase uses dimethylallyl diphosphate and ()-(2S)-naringenin to produce diphosphate and 8-prenylnaringenin.

Biodegradation

Cunninghamella elegans, a fungal model organism of the mammalian metabolism, can be used to study the naringenin sulfation.[16]
