Rosemary and cancer prevention: preclinical perspectives.
Ngo SN1, Williams DB, Head RJ.
Abstract: Colorectal cancer is the second leading cause of
cancer death in Australia. Nutrition, particularly intake of vegetables and
certain plant components, has been reported to have a major role in cancer risk
reduction. Recently, there has been a growing research interest in rosemary,
a common household plant grown in many parts of the world. This study aims to
review scientific evidence from all studies, published from 1996 to March 2010
that examined the protective effects of rosemary on colorectal cancer and other
types of cancer. Literature evidence from animal and cell culture studies demonstrates
the anticancer potential of rosemary extract, carnosol, carnosic acid, ursolic
acid, and rosmarinic acid. No evidence for other rosemary constituents was found.
The reported anticancer properties were found to arise through the molecular
changes in the multiple-stage process of cancer development, which are dose
related and not tissue or species specific. This is evidenced by the ability
of rosemary to suppress the development of tumors in several organs including
the colon, breast, liver, stomach, as well as melanoma and leukemia cells. The
results suggested that the different molecular targets modulated by rosemary
and its active constituents are useful indicators of success in clinical cancer
chemo-prevention trials.

Antioxidant and antimicrobial activities of rosemary extracts linked
to their polyphenol composition. Moreno S1, Scheyer T, Romano CS, Vojnov
AA.
Abstract: Rosmarinus officinalis extracts were investigated
by a combination of bioassays and biochemical analysis to identify bioactive
compounds. The 2,2-diphenyl-2-picrylhydracyl hydrate (DPPH) radical scavenging
method, Folin-Ciocaulteau method and HPLC chromatography were used to study
the distribution and levels of antioxidants (AOXs). Antimicrobial activity analysis
was carried out using the disk diffusion and broth dilution techniques. A good
correlation between the AOX activities and total phenol content in the extracts
was found. Although all rosemary extracts showed a high radical scavenging activity,
a different efficacy as antimicrobial agent was observed. Methanol extract containing
30% of carnosic acid, 16% of carnosol and 5% of rosmarinic acid was the most
effective antimicrobial against Gram positive bacteria (minimal inhibition concentration,
MIC, between 2 and 15 mug/ml), Gram negative bacteria (MIC between 2 and 60
mug/ml) and yeast (MIC of 4 mug/ml). By contrast, water extract containing only
15% of rosmarinic acid showed a narrow activity. MIC value of the methanol and
water extracts is in a good correlation with the values obtained with pure carnosic
acid and rosmarinic acid, respectively. Therefore, our results suggested that
the antimicrobial rosemary extracts efficacy was associated with their specific
phenolic composition. Carnosic acid and rosmarinic acid may be the main bioactive
antimicrobial compounds present in rosemary extracts. From a practical point
of view, rosemary extract may be a good candidate for functional foods as well
as for pharmaceutical plant-based products.

Anti-inflammatory and antinociceptive effects of Rosmarinus officinalis
L. essential oil in experimental animal models.

Abstract
Rosmarinus officinalis L. (Family Lamiaceae), popularly named rosemary, is a
common household plant grown in many parts of the world, including Brazil. Rosemary
leaves are used for food flavoring and have been used in folk medicine for many
conditions; they have antispasmodic, analgesic, antirheumatic, carminative,
cholagogue, diuretic, expectorant, and antiepileptic effects. The objective
of this study was to evaluate the effects of rosemary essential oil (REO) on
experimental models of nociception and inflammation in animals. The anti-inflammatory
effect of REO was evaluated by inflammatory exudate volume and leukocyte migration
in carrageenan-induced pleurisy and carrageenan-induced paw edema tests in rats.
Antinociception was evaluated using the acetic acid-induced writhing and hot
plate tests in mice. REO (500 mg/kg) significantly reduced the volume of pleural
exudate and slightly decreased the number of cells that had migrated compared
with the control animals. At doses of 250, 500, and 750 mg/kg, REO significantly
inhibited carrageenan-induced edema 1-4 hours after injection of the phlogistic
agent. In the hot plate test, REO administration (125, 250, and 500 mg/kg) showed
unremarkable effects on response latency, whereas control injection of meperidine
induced significant antinociceptive effects. REO at doses of 70, 125, and 250
mg/kg had a significant antinociceptive effect in the acetic acid-induced abdominal
writhing test compared with control animals. These data suggest that REO possesses
anti-inflammatory and peripheral antinociceptive activity.J Med Food. 2008 Dec;11(4):741-6.
