Oxidative damage is one of the hallmarks of the aging process. The current study evaluated effects of two proprietary antioxidant-based ingredients， rosemary extract and spearmint extract containing carnosic acid and rosmarinic acid， respectively， on learning and memory in the SAMP8 mouse model of accelerated aging. The two rosemary extracts contained carnosic acid and one spearmint extract contained 5% rosmarinic acid. Three doses of actives in each extract were tested: 32， 16， 1.6 or 0 mg/kg. After 90 days of treatment mice were tested in T-maze foot shock avoidance， object recognition and lever press. Rosemary extract containing 60% carnosic acid improved acquisition and retention in T-maze foot shock， object recognition and lever press. Rosemary extract with 10% carnosic acid improved retention in T-maze foot shock avoidance and lever press.
