Acetylcholinesterase inhibition, antioxidante activity and toxicity of peumus b...
Falé, P. L.; Amaral, F.; Amorim Madeira, P. J.; Sousa Silva, M.; Florêncio, M. H.; Frazão, F. N.; Serralheiro, M. L.This work aimed to study the inhibition on acetylcholinesterase activity (AChE), the antioxidant activity and the toxicity towards Caco-2 and HeLa cells of aqueous extracts of Peumus Boldus. An IC(50) value of 0.93 mg/mL, for AChE inhibition, and EC(50) of 18.7 μg/mL, for the antioxidant activity, was determined. This activity can be attributed to glycosylated flavonoid derivatives detected, which were the main...
