Although quinic acid failed, chlorogenic and caffeic acids significantly ameliorated the H2O2-induced decline in TTC staining intensities.
Caffeic acid is susceptible to decarboxylation reactions, which can be promoted by either thermal conditions or enzymatic action through decarboxylases to generate vinylphenols (RIZZI & BOEKLEY, 1992).

Rosemary contains both caffeic acid and rosmarinic acid which act as a powerful anti-inflammatory making it ideal for those who suffer with auto-immune disorders such as rheumatoid arthritis, chronic fatigue syndrome, and fibromyalgia.
Caffeic acid was chosen as representative of the phenolic acids since it has also been demonstrated to be inhibitory on adipogenesis [27].
