Application

Carnosic acid from Rosmarinus officinalis is used to study its mechanisms as an antioxidant that protects lipids from peroxidation and proteins from carbonylation. Carnosic acid is used to assess its neuroprotective activies including its ability to modulate the neurotoxic effects of 6-hydroxydopamine (6-OHDA). Carnosic acid may also be used to study it anticancer potential.
Phenolic compound that is naturally occurring with antioxidant properties. Inhibits lipid peroxidation which is caused by NADH or NADPH oxidation.
