Plants form ellagic acids through hydrolysis of tannins (ellagitannin), and urolithins are microbial metabolites of ellagic acids in humans.The highest levels of ellagic acid are found in raw chestnuts, walnuts, pecans, cranberries, raspberries, strawberries, and grapes, as well as distilled beverages. It is also found in peaches and pomegranates.Ellagic acid is soluble in DMSO, which should be purged with an inert gas. The solubility of ellagic acid in DMSO is approximately 0.14 mg/ml. Ellagic acid is sparingly soluble in aqueous buffers. An aqueous solution can best be prepared by diluting the organic solution into aqueous buffers or isotonic saline.
