Antiglycation Potential and Antioxidant Activity of Genipap (genipa Americana L.) in Oxidative Stress Mediated by Hydrogen Peroxide on Cell Culture

Genipa americana L. is a plant widely used by folk medicine for the prevention and as an aid in the treatment of various diseases. In this work, we evaluated the anti-glycant and antioxidant activities of genipap fruit juice, as well as the influence of different temperatures (−6°C and −80 °C) on the preservation of phenolic compounds. Purified extract from G. americana showed anti-glycant activity reducing the formation of fructosamine by up to 53% and recovered viability of cells under oxidative stress induced by H2O2. HPLC/UV-Vis analysis identified cinnamic acid as a bioactive substance and possibly responsible for the biological activities described above. Taken together, these results indicate that G. americana is a rich source of cinnamic acid with appreciable antioxidant and anti-glycant potential.
