Rosmarinic Acid Powder CAS 20283-92-5
What is Rosmarinic Acid?
Rosmarinic acid is a valuable natural active ingredient primarily derived from the Rosmarinus officinalis plant, which is widely distributed throughout the Mediterranean region. The leaves of this common herb are rich in rosmarinic acid, making them an ideal source for its extraction. Initial extraction from the essential oil of rosemary leaves is achieved through distillation, followed by fine purification to yield a high-purity rosmarinic acid product.
As a highly regarded "natural health supplement," rosmarinic acid, with its multiple biological activities, holds broad promise for application in healthcare. Its unique chemical structure and physiological functions make it a key focus of current natural product research and development.

What Are The Benefits?
Antioxidant Benefits
Rosmarinic acid is rich in powerful antioxidants that significantly scavenge free radicals in the body and reduce oxidative stress damage. This effect not only delays cell aging and improves skin condition, but also enhances immunity and reduces the risk of various chronic diseases.
Anti-Inflammation and Tissue Repair
By inhibiting the release of inflammatory factors, rosmarinic acid can effectively relieve inflammatory symptoms such as arthritis and enteritis. It also accelerates wound healing and promotes tissue regeneration, shortening the repair cycle.
Antibacterial and Antiviral Properties
Rosmarinic acid has inhibitory effects on bacteria, fungi, and some viruses, and is clinically used as an adjunct to the treatment of infectious diseases such as skin diseases and oral ulcers.
Cardiovascular Protection
By improving vascular function and regulating blood lipids, it reduces the risk of arteriosclerosis and has potential benefits in preventing cardiovascular and cerebrovascular diseases.
Neurocognitive Improvement
Rosmarinic acid can enhance memory and concentration, positively impacting learning efficiency and work performance.
Applications
Health Product Applications
Rosmarinic acid, with its unique aromatic, stomachic, and sedative properties, holds significant value in the health product sector. It is not only used to relieve headaches and improve symptoms such as neurasthenia, but is also formulated into various nutritional supplements, such as tablets and capsules, to provide consumers with natural health support. Its multiple physiological activities make it a key functional ingredient in the development of modern health products.
Food Industry Applications
As a highly effective natural antioxidant, rosmarinic acid plays a key role in food processing. It effectively slows down the oxidative deterioration of foods, significantly extending their shelf life while preserving their original color and taste. It is particularly useful in easily oxidized foods, such as meat products, high-fat foods, and edible oils, preventing quality deterioration and flavor loss due to oxidation, thereby ensuring food freshness and safety.
Cosmetic Applications
Recent research indicates that rosmarinic acid exhibits significant UV protection. Its mechanisms of action include reducing lipid peroxidation, regulating ATP levels, and influencing glutathione metabolism, thereby effectively reducing UV-induced free radical production and alleviating DNA damage. These properties make rosmarinic acid an ideal active ingredient for the development of natural sunscreen products that provide multiple photoprotections to the skin.
