Rosemary is a common herb, widely distributed in the Mediterranean region. Its leaves are rich in rosmarinic acid, which is the main raw material for preparing rosmarinic acid oil. Rosmarinic can be extracted by distilling the volatile oil in rosemary leaves, and then high-purity rosmarinic acid powder can be obtained by further purification and processing. Rosmarinic acid has excellent antioxidant, anti-inflammatory and antibacterial properties, which not only provides delicious aroma and anti-corrosion for food, but also plays an active role in medicine and health care. It has been widely used in various fields such as food, medicine and cosmetics since ancient times.

What is the antioxidant mechanism of Rosmarinic Acid Powder?
The composition of rosemary is complex, including monoterpenes, sesquiterpenes, diterpenes, triterpenoids, flavonoids, fatty acids and other chemical components, and the content distribution of these components is relatively balanced. Rosemary contains about 5% acidic components, mainly rosmarinic acid, caffeic acid and chlorogenic acid. Studies show that rosmarinic acid powder has strong free radical scavenging activity and antioxidant effect, which is related to its molecular structure. The research team found that Rosmarinic has the following three antioxidant mechanisms:
(1) Rosmarinic acid competes with unsaturated fatty acids to combine with lipid peroxides, so as to terminate the chain reaction of lipid peroxidation and reduce the rate of lipid peroxidation.
(2) Inhibition of protein synthesis and nitric oxide production of inducibleinitricoxidesynthase (iNOS).
(3) Diatomic acid can inhibit the respiratory burst of neutrophils and inhibit the release of lysosomes by reducing the intracellular calcium concentration;
(4) Inhibiting the oxidation of low density lipoprotein regulated by endothelial cells.
What's the latest research on the antibacterial effect of Rosmarinic acid powder?
Rosmarinic acid is a fat-soluble compound,. Its molecular structure is stable, except for its strong activity of scavenging free radicals in the body and its antioxidant effect. It also has strong and broad-spectrum antibacterial effect. Rosmarinic acid powder has antibacterial activity, which was first discovered by researchers in the inhibition experiment of Escherichia coli and Staphylococcus aureus, and its inhibitory effect on Staphylococcus aureus is far greater than that of Escherichia coli. Its bacteriostatic mechanism is (1) inhibiting the activity of DNA polymerase, which leads to the influence of DNA replication, thus inhibiting the growth of bacteria; (2) By changing the permeability of bacterial cell membrane, reducing sugar, protein, etc. will leak, and cell metabolism will be affected.
What are the market values of Rosmarinic acid powder?
Rosmarinic acid is a natural antioxidant with strong antioxidant activity, which is stronger than vitamin E, caffeic acid, chlorogenic acid, folic acid, etc., and helps to prevent cell damage caused by free radicals, thus reducing the risk of cancer and arteriosclerosis. Rosmarinic acid has strong anti-inflammatory activity, at the same time, rosmarinic acid also has antibacterial, antiviral and antitumor activities. Rosmarinic acid has the characteristics of inhibiting acute and chronic infections, resisting ultraviolet rays and inhibiting elastin degradation, which has made it an additive for cosmetics. At present, rosmarinic acid powder has shown its important application value in the fields of pharmacy, food, cosmetics and so on.
1. Food field: Rosmarinic acid, as a natural and efficient antioxidant, can be used in animal and vegetable oils, dairy products, oil-rich foods, sweets and baked foods instead of BHA and BHT; It can also be used as a spice in various soups and flavored foods; And has antiseptic and antibacterial effects. In Japan, perilla extract rich in rosmarinic acid is used as decoration to improve the shelf life of fresh seafood.
2. Health care products: anti-tumor, anti-hepatitis, liver injury protection, anti-nephritis, anti-thrombosis and anti-platelet aggregation, as well as refreshing, enhancing memory, improving tension and sleepiness.
3. Cosmetic field: used in skin care products, it can play a role in removing spots, resisting oxidation, increasing skin elasticity, delaying aging and so on; Used in shampoo and hair care products, it can promote scalp blood circulation, improve alopecia, reduce dandruff, stimulate hair growth and moisturize hair. Therefore, rosmarinic acid can be used as an excellent additive in cosmetics.
