What is Carnosic acid powder?
Carnosic acid powder is a diterpenoid compound isolated from the leaves of rosemary. It is a white or yellowish-white powder, easily soluble in oils and organic solvents such as ethanol, ethyl acetate, acetone, chloroform, and insoluble in water. Carnosic acid is suitable for the antioxidant effect of oil-soluble ingredients. It is used in seasoning sauces, pet food and feed, and has antioxidant and anti-aging effects; strong weight loss and lipid-lowering effects; treatment of cardiovascular disease and anti-cancer effects.
Carnosic acid powder,Rosemary is a herbaceous plant of the Lamiaceae family, native to southern European countries. It contains a variety of effective ingredients such as carnosic acid, rosmarinol, rosmarinic acid, carnosinol, epirosmarinol, isorosmarinol, and rosmarindiphenol. Among them, the highly effective antioxidant substances are carnosic acid, rosmarinol, and carnosinol. The fat-soluble rosemary extract is a light yellow to yellow-brown powder or brown paste, insoluble in water, soluble in ethanol and oil; the water-soluble rosemary extract is a brown powder with a unique smell of rosemary. Heat resistance (stable at 200℃) and UV resistance have good linearity, which can effectively prevent the oxidation of oils and fats.
Rosemary extract can be divided into oil-soluble (antioxidant) and water-soluble (antioxidant and preservative). The active ingredient of the former is mainly carnosic acid, and the latter is mainly rosmarinol. Rosemary extract is natural and non-toxic, and its antioxidant effect is far higher than the existing natural antioxidants such as vitamin C, vitamin E, and tea polyphenols. It is 2 to 4 times that of synthetic antioxidants BHA and BHT. Its structure is stable and not easy to decompose. It can withstand high temperatures of 190℃ to 240℃, which completely overcomes the fatal weakness of most natural antioxidants such as vitamin C and tea polyphenols that decompose at high temperatures. Therefore, compared with other similar products, it has the advantages of higher efficiency and broader spectrum. Researchers found that when rosemary extract is 300mg/kg, its antioxidant activity is equivalent to 200mg/kgBHA, which is greater than 100mg/kg tocopherol. Generally, its antioxidant capacity increases with the amount added, but at high concentrations, it can cause oil precipitation and discoloration of water-containing foods.
The antioxidant function of rosemary mainly lies in its ability to quench singlet oxygen, scavenge free radicals, chelate metal ions and synergistically enhance the effect of organic acids, etc.
Pharmacological effects
(1) Antibacterial effect
Studies have shown that carnosic acid has different degrees of inhibitory effects on Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Hansen yeast, and can be used as a food preservative.
(2) Antioxidant effect
Carnosic acid has good free radical scavenging and antioxidant effects. Its DPPH and ABTS free radical scavenging ability and iron reduction antioxidant ability are stronger than VE, and 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 and the decomposition of polyene fatty acids in oils and fats, thereby extending the shelf life of oils and fats. In addition, studies have found that carnosic acid can effectively scavenge oxygen free radicals in mouse liver cells, reduce the production of lipid peroxides, and thus stabilize cell membranes; carnosic acid can also inhibit the oxidation reaction of low-density chemicalbook lipoproteins, thereby effectively preventing the occurrence of atherosclerosis.
(3) Other effects
Research has 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 blood malignancies, cardiovascular diseases and cancer. Kaloustian et al. introduced that rosemary extracts such as carnosic acid have certain therapeutic effects on heart disease and respiratory diseases, have antibacterial effects, and can also inhibit HIV infection. Ninomiya et al. reported that rosemary extracts such as carnosic acid can not only effectively regulate fat absorption to control human weight and achieve the purpose of weight loss, but also can treat inflammation, sore throat, indigestion, prevent Alzheimer's disease, treat diabetes, and promote the production of nerve growth factor.
Chemical properties
Carnosic acid is a diterpenoid compound monomer derived from the extract of Rosemary RosmarinusofficinalisL. of the Lamiaceae family. It has low polarity, is insoluble in water, and is easily soluble in oil. It has high antioxidant properties, is safe and non-toxic, and is resistant to high temperatures. Due to its obvious antioxidant effect, safety, non-toxicity, and high temperature resistance, it is still stable and has antioxidant properties at 200°C, making it still applicable in food processing techniques such as boiling, frying, deep-frying, and baking, and is considered a multi-life antioxidant.
