Rosmarinic acid is a natural polyphenolic compound widely distributed throughout the plant kingdom, classified as a phenylpropanoid. Chemically, it is an ester formed from caffeic acid and 3,4-dihydroxyphenyllactic acid; it exhibits significant antioxidant activity, and its capacity to scavenge free radicals surpasses that of common antioxidants such as Vitamin E and caffeic acid. Rosmarinic acid was first identified in rosemary (*Rosmarinus officinalis*)—a plant belonging to the Lamiaceae family—and has subsequently been discovered in plants of other families, including the Boraginaceae and Cucurbitaceae.

Function
As a natural antioxidant, rosmarinic acid can be utilized in animal and vegetable oils, dairy products, baked goods, and similar items to replace synthetic antioxidants such as BHA and BHT, thereby preventing lipid oxidation and rancidity. Furthermore, it serves as a preservative to extend food shelf life and is employed in the preservation of products such as seafood.
In the cosmetics industry, rosmarinic acid is widely incorporated into anti-aging skincare products, shampoos, and conditioners due to its exceptional antioxidant and photoprotective properties. It effectively scavenges free radicals in the skin, inhibits melanin production, stimulates blood circulation in the scalp, and helps alleviate issues related to hair loss and dandruff.
Rosmarinic acid has been developed into various pharmaceutical formulations for the treatment of conditions including cardiovascular diseases, hepatitis, nephritis, and tumors. As a dietary supplement, it offers benefits such as boosting alertness, enhancing memory, and improving mood.
