Product Application of Rosmarinic acid CAS#20283-92-5
Rosmarinic acid is a natural phenolic compound featuring antioxidant and anti-inflammatory effects. At 25 μg/mL, it reduces lipid peroxidation in rat liver microsomes by 90%. It blocks endotoxin-triggered complement activation and prostacyclin production. It also inhibits 5-HETE and LTB4 synthesis from human PMNL at 10⁻⁵ to 10⁻³ M.
