Rosmarinic acid is a natural polyphenol antioxidant carboxylic acid found in many Lamiaceae herbs used commonly as culinary herbs such as lemon balm, rosemary, oregano, sage, thyme and peppermint. Chemically, rosmarinic acid is an ester of caffeic acid with 3, 4-dihydroxyphenyl lactic acid. It is a red-orange powder that is slightly soluble in water, but well soluble in most organic solvents. Because of its antioxidant activity, it has beneficial effects in humans.
New research suggests Carnosic acid (CA), the active ingredient in the herb rosemary, is neuroprotective, without producing the serious adverse effects characteristic of many agents used to treat neurodegenerative disease. Studies show that CA activates a novel signaling pathway that protects brain cells from free radical damage, seen in stroke and other neurodegenerative conditions such as Parkinson's and Alzheimer's diseases.
Carnosol and carnosic acid have been suggested to account for over 90% of the antioxidant properties of rosemary extract. Carnosol and carnosic acid are powerful inhibitors of lipid peroxidation in microsomal and liposomal systems, more effective than propyl gallate. Carnosol and carnosic acid are good scavengers of peroxyl radicals (CCl3O2.) generated by pulse radiolysis, with calculated rate constants of 1-3 x 10(6) M-1 s-1 and 2.7 x 10(7) M-1 s-1 respectively. Carnosic acid reacted with HOCl in such a way as to protect the protein alpha 1-antiproteinase against inactivation. Both carnosol and carnosic acid stimulated DNA damage in the bleomycin assay but they scavenged hydroxyl radicals in the deoxyribose assay. The calculated rate constants for reaction with .OH in the deoxyribose system for carnosol and carnosic acid were 8.7 x 10(10) M-1 s-1 and 5.9 x 10(10) M-1 s-1 respectively. Carnosic acid appears to scavenge H2O2, but it could also act as a substrate for the peroxidase system. Carnosic acid and carnosol reduce cytochrome c but with a rate constant significantly lower than that of O2(-.).
Rosemary (Rosmarinus officinalis) is a woody, perennial herb with fragrant evergreen needle-like leaves. It is native to the Mediterranean region. It is a member of the mint family Lamiaceae, which also includes many other herbs. Rosemary is now cultivated widely in other parts of the world, although it thrives in a warm and relatively dry climate.
The name rosemary has nothing to do with the rose or the name Mary, but derives from the Latin name rosmarinus, which is from "dew" (ros) and "sea" (marinus), or "dew of the sea"apparently because it is frequently found growing near the sea.
Rosemary (Rosmarinus officinalis) is widely used as a culinary herb, especially in Mediterranean dishes, and is also used as a fragrant additive in soaps and other cosmetics. Traditionally, rosemary has been used by herbalists to improve memory, relieve muscle pain and spasm, and stimulate hair growth, and support the circulatory and nervous systems. It is also believed to affect the menstrual cycle, act as an abortifacient (inducing miscarriage), relieve menstrual cramps, increase urine flow, and reduce kidney pain (for example, from kidney stones).
Rosemary contains a number of potentially biologically active compounds, including antioxidants such as Carnosic acid, Carnosol and rosmarinic acid. Other bioactive compounds include camphor (up to 20% in dry rosemary leaves), caffeic acid, ursolic acid, betulinic acid, rosmaridiphenol, and rosmanol.
Recently, rosemary has been reported to have strong antioxidant characteristics. The strong antioxidative activity of rosemary is caused mainly by phenoli
