Raspberry ketone is a natural phenolic compound that is the primary aroma compound of red raspberries. It is used in perfumery, in cosmetics, and as a food additive to impart a fruity odor.

In plants, raspberry ketone is synthesized from coumaroyl-CoA.[2] But since the natural abundance of raspberry ketone is very low, it is prepared industrially by a variety of methods from chemical intermediates.[3]

When given to mice in high doses (up to 2% of food intake), raspberry ketone has been shown to prevent high-fat-diet-induced elevations in body weight.[4] This effect is reported to stem from the alteration of lipid metabolism, increasing norepinephrine-induced lipolysis. Although products containing this compound are marketed for weight loss, this effect has not been demonstrated in humans.
