Food Safety and Health, EarlyView.Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.

Food Safety and Health, EarlyView.Pomegranate peel extract enhanced the nutritional, physicochemical, and microbiological qualities of yoghurt. It is a rich source of polyphenolic compounds that eliminates Staphylococcus aureus in yoghurt at 0.1% and 0.3% concentrations without altering its pH value. ABSTRACT The use of natural additives, particularly pomegranate peel extract (PPE), to

Structural and Antioxidative Features of Chlorogenic Acid
Croatica Chemica Acta, 2016 This work contributes to the structure clarification of chlorogenic acid (5-O-caffeoylquinic acid, 5CQA) by comparing the experimental and simulated IR, Raman, 1H-NMR, 13C-NMR, and UV-vis spectra. The lowest-energy conformers in the gas-phase and solution were used for all calculations. Very good agreement between all experimental and simulated spectra

Iron Chelation by Chlorogenic Acid as a Natural Antioxidant [PDF]
Bioscience, Biotechnology, and Biochemistry, 1998 Chlorogenic acid, a dietary antioxidant, effectively inhibited the iron-induced lipid peroxidation of bovine liver microsomes in a concentration-dependent manner. In the Fenton-type reaction, chlorogenic acid inhibited the production of the hydroxyl radical by iron-EDTA or iron-ADP, while iron plus chlorogenic acid did not generate the hydroxyl radical.
