Application
Ellagic acid, a cream to light yellow crystalline solid, is derived from various plants like Mangifera indica and Eucalyptus citriodora, and is soluble in methanol, ethanol, DMSO, and other organic solvents. Naturally occurring in fruits such as raspberries, strawberries, cranberries, and pomegranates, ellagic acid serves several vital roles. As a phenolic compound and antioxidant, it is utilized in both medicine and cosmetics due to its diverse biological activities, which include hemostatic, antineoplastic, antimutagenic, antiproliferative, and antiviral properties. Additionally, it serves as a skin lightening agent and shows potential in inhibiting enzymes like DNA topoisomerases and glycogen phosphorylase. Its antitumor and geroprotective effects, along with its role as a glutathione S-transferase inhibitor and its involvement in blood coagulation processes, underline its considerable potential health benefits and functional versatility.
