Carnosic acid is a diterpenoid that acts as an effective lipid peroxidation inhibitor in liposomal and microsomal environments, with antioxidant properties. Carnosic acid has been reported to scavenge peroxyl radicals, H2O2, reduce cytochrome C, and act more potently than Propyl gallate.Studies indicate that Carnosic acid protects red cells from oxidative hemolysis and in the xanthine/xanthine oxidase system inhibits superoxide anion production. In addition, data suggests that Carnosic acid activates PPARγ (peroxisome proliferator activated receptor γ).
