CARNOSIC ACID CAS 3650-09-7 10% Rosemary Leaf Extract

Rosemary extract can be divided into two types: oil-soluble (antioxidants) and water-soluble (antioxidants and preservatives). The former is mainly carnosic acid, and the latter is mainly rosmanol. Rosemary extract is natural and non-toxic, and its antioxidant effect is much higher than the existing natural antioxidants such as vitamin C, vitamin E, and tea polyphenols. It is 2 to 4 times more powerful than the synthetic antioxidants BHA and BHT, and its structure It is stable, not easy to decompose, and can withstand high temperatures of 190°C to 240°C. It completely overcomes the fatal weakness of most natural antioxidants such as vitamin C and tea polyphenols that decompose when exposed to high temperatures. Therefore, compared with other similar products, it is more efficient and wider. spectrum advantage. Researchers found that at 300 mg/kg, the antioxidant activity of rosemary extract was equivalent to 200 mg/kg BHA, which was greater than 100 mg/kg tocopherol. Generally, its antioxidant capacity increases with the increase in the amount added, but at high concentrations, it can precipitate oil and cause discoloration of water-containing foods. The antioxidant function of rosemary mainly lies in its synergistic effect of quenching singlet oxygen, scavenging free radicals, chelating metal ions and organic acids, etc.

Pharmacological effects of carnosic acid
1) Research on antibacterial effects shows that carnosic acid has varying degrees of inhibitory effects on Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Hansenula yeasts, and can be used as a food preservative.
2) Antioxidant effect: Carnosic acid has good free radical scavenging and antioxidant effects. Its DPPH, ABTS free radical scavenging ability and iron reducing antioxidant ability are stronger than VE, slightly weaker than the synthetic antioxidant TBHQ; its reducing ability is stronger than VE and TBHQ. Carnosic acid is fat-soluble and can effectively inhibit the formation of peroxides in oils and the decomposition of polyene fatty acids, thus extending the shelf life of oils. In addition, studies have found that carnosic acid can effectively scavenge oxygen free radicals in mouse liver cells and reduce the production of lipid peroxides, thereby stabilizing cell membranes; carnosic acid can also inhibit the oxidation reaction of low Chemicalbook density lipoproteins, thereby effectively Prevent the occurrence of atherosclerosis.
3) Studies on other effects have found that carnosic acid has an inhibitory effect on the proliferation of HL-60 cells, and is expected to become a new drug for the treatment of hematological malignancies, for the treatment of cardiovascular diseases and anti-cancer. Kaloustian et al. introduced that carnosic acid and other rosemary extracts have certain therapeutic effects on heart disease and respiratory diseases, have antibacterial effects, and can also inhibit HIV infection. Ninomiya et al. reported that carnosic acid and other rosemary extracts can not only control people's weight by effectively regulating fat absorption, thereby achieving the purpose of weight loss, but can also treat inflammation, treat sore throat, treat indigestion, and prevent aging. Dementia, treating diabetes, and promoting the production of nerve growth factors, among others.
