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
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
