1. Scavenging free radicals
Ellagic acid has a strong ability to scavenge free radicals and antioxidants. Ellagic acid has a scavenging effect on oxygen free radicals and hydroxyl free radicals, and its ability to scavenging free radicals is higher than that of antioxidants such as sesamol, olive leaf extract and lutein.
2. Inhibit lipid peroxidation
Ellagic acid can also strongly inhibit lipid peroxidation induced by adriamycin, inhibit iron myoglobin/hydrogen peroxide-dependent lipid peroxidation, and prevent lipid peroxidation induced by foreign substances in T cells LPO, inhibits the production of reactive oxygen species (ROS), and improves cell death caused by cytotoxins.
3. Other antioxidant activities
Ellagic acid effectively inhibits the oxidation of DCDHF induced by peroxynitrite and the oxidation of peroxynitrite itself. At the same time, ellagic acid prevents pTZ 18U plasmid DNA from single-strand breaks and nitration of tyrosyl groups in calf serum albumin induced by pernitrite. Therefore, in vitro, ellagic acid protects biomolecules from oxidative and nitrifying damage caused by peroxynitrite.
