Rosmarinic acid is a water-soluble natural phenolic acid compound isolated from rosemary of the Lamiaceae.Rosmarinic acid extract is a natural antioxidant with strong antioxidant activity.Its antioxidant activity is stronger than vitamin E,caffeic acid,chlorogenic acid,folic acid and so on.Rosmarinic acid uses to prevent cell damage caused by free radicals.Thereby reducing the risk of cancer and arteriosclerosis.Rosmarinic acid has a broad-spectrum antibacterial activity, and has an inhibitory effect on bacteria and fungi.Rosmarinic acid has a certain effect on the permeability of bacterial cell membrane, protein metabolism and DNA replication,thereby exerting its antibacterial effect.
Rosmarinic acid has strong free radical scavenging activity and antioxidant effect in the body.In cosmetics field: used in skin care products,can eliminate pigmentation,anti-oxidation,increase skin elasticity,delay aging,etc.
