It has been widely used in medicine and cosmetics. Let’s take a look at the specific effects of rosmarinic acid below.
Rosmarinic acid
1、 Medicine
1. Antioxidation
Rosmarinic acid can terminate the chain reaction of lipid peroxidation by competitively binding lipid peroxy; It can also play an antioxidant role by inhibiting the protein synthesis of inducible nitric oxide synthase and the production of nitric oxide.
2. Antibacterial effect
Rosmarinic acid has broad-spectrum antimicrobial activity and has inhibitory effects on bacteria and fungi.
3. Antiviral effect
Rosmarinic acid has inhibitory effect on human immunodeficiency virus, herpes virus and Japanese encephalitis virus.
4. Anti inflammatory effect
Rosmarinic acid has good anti-inflammatory activity. Because of its anti-inflammatory efficiency, low toxicity, low adverse reactions and other advantages.
2、 Cosmetics
Photoprotective effect of rosmarinic acid. Solar ultraviolet rays and other ionized radiation lead to the production of reactive oxygen species, causing cell DNA damage and changing the stability of the internal environment of the skin. Rosmarinic acid can inhibit the changes of skin caused by ultraviolet radiation, and has photoprotective properties for human keratinocytes. Therefore, rosmarinic acid can be used in skin care cosmetics, can resist the oxidative stress caused by UVA, and can be used as a light protective agent in dermatology.
