Ellagic acid (EA) (2,3,7,8-tetrahydroxy[1]-benzopyrano [5,4,3-cde][1]benzopyran-5,10-dione) is a phenolic constituent that exists in such fruits and nuts as raspberries, strawberries, walnuts, longan seed, mango kernel (Soong and Barlow, 2004) and pomegranate (Wang et al.

One of the chemicals, ellagic acid, proved particularly potent: It dramatically slowed the growth of existing fat cells and formation of new ones, and it boosted metabolism of fatty acids in liver cells.
