Composition of caffeic acid: Now caffeic acid is not extracted from traditional Chinese medicine, but chemically synthesized by Dezhou Deyao Company through high-tech patented technology. Exclusive production, the purity is 99.9%, and two invention patents of raw materials and preparations are obtained. Caffeic acid, with chemical name of 3-(3,4-dihydroxyphenyl)-acrylic acid, belongs to phenolic acids with molecular weight of 180. 16. China Pharmaceutical University has conducted basic research on caffeic acid.
We see that the chemical structure of caffeic acid contains two phenolic hydroxyl groups, which determines that caffeic acid has excellent antioxidant properties and is a natural and safe free radical quencher.
