Source
Cynara scolymus L is commonly known as artichoke or the globe artichoke ,it is a species
of thistle cultivated primarily as a food but also a medicinal plant .The edible portion of the plant
consists of the flower buds before the flowers come into bloom. And the leaf of artichoke is the
part that used as one of the world’s oldest herbal medicine with multiple health benefits.It has
been known by the ancient Egyptians, and the ancient Greeks and Romans used it as a digestive
aid. Long known as an herbal medicine, the dried leaves of artichoke have been used in folk
medicine because of their hypolipidemic and hepatoprotective activities.
Main bio-actives
The artichoke leaves contain a number phenolic acids, flavonoids (rutin, luteolin), cynarin and
sesquiterpenes (especially caryophyllene and beta-selinene). It also contains tannins, sugar
substances, inulin, mucus substances, phytosterols (taraxasterol), essential oil, provitamin A and
several enzymes.
Cynarine is a chemical constituent in Cynara scolymus. The majority of the cynarine found in
artichoke is located in the pulp of the leaves, though dried leaves and stems of artichoke also
contain it. It inhibits taste receptors, making water (and other foods and drinks) seem sweet.
Functions
Antioxidative
The antioxidantive effect of artichoke extract was investigated in 2002.The report on J Agric Food
Chem showed the methanol and water of blanched (thermally treated) artichoke yielded (24.3
grams per 100 g of dry extract)more antioxidant phenolics than other byproducts with possible
industrial applicability.
Futher studies were conducted to examine the antioxidative characteristics of Cynara scolymus
inconsideration of its application in food industry and health-promoting products.One study
published on Food and Nutrition Sciences in 2014 determined the extract exhibited a good
polyphenol content (528 μg GAE/g) and antioxidant activity (EC50 less than 5 mg). Further
investigation shows the extract exhibited antimicrobial activity against Escherichia coli,
Staphylocccus aureus, Pseudomonas aeruginosa, Enterococcus faecalis and Bacillus cereus
pathogen strains.These finding suggested that Cynara scolymus extract is a good source of
health-promoting polyphenols, encouraging a nutraceutical use of such ecotype, for several
phyto-pharmaceutical applications.
Anti-inflammatory
There are researches investigate the anti-inflammatory activity of artichoke leaf extracts.One of
the investigation was released on Molecules in 2014 demonstraed that
artichoke exert anti-inflammatory activity by downregulating the expression of Inducible Nitric
Oxide Synthase(iNOS) in human coronary smooth muscle cells.As iNOS produces large quantities
of NO upon stimulation, such as by proinflammatory cytokines and associates with a key
pathogenic mechanism in many pathological conditions such as septic shock and stroke.The study
result shows the polyphenolic compounds ,caffeoylquinic acid ,flavones and the anthocyanidins
from artichoke all downregulated iNOS mRNA expression with cynarin being the most potent one
both in HCASMC and at the protein level.
Gastrointestinal
Artichoke (Cynara scolymus L) contains indigestible organic matter that reaches the colon and is
substrate for intestinal microbiota. A study of the capacity of artichoke to modify metabolic
activities of colonic bacterial enzymes were conducted in the cecal content of Wistar rats.In
administrated rats ,Artichoke modified bacterial enzyme activities (increased β-glucuronidase,
β-glucosidase, and nitroreductase and reduced nitrate reductase and azoreductase activities), which
enhances the capacity of microbial enzymes to metabolize glycosides and nitrocompounds.
Another research published on Biol. Pharm. Bull in 2010 demonstrated that artichoke leaf extract
is effective against acute gastritis due to its cynaropicrin in study on rats .Cynaropicrin from the
artichoke leaf extract prevented gastric mucosal injury in animal models as it dosedependently
prevented the decrease in gastric mucus content and gastric juice by absolute ethanol.These
finding suggest that the extract of artichoke may beneficial to the gastrointestinal health.
Hypotensive and anti-hyperlipidemic
Artichoke has been long known as an herbal medicine for treating hypertension,hyperglycemic
and hyperlipidemic.
Study reported on Journal of Dietary Supplements showed significant activity of artichoke leaf
extract in modulating both systolic and diastolic blood pressure in a a randomized,
placebo-controlled human trial.
Further investigation conducted in 2012 to study the effects of artichoke leaf extract in treatment
of hypercholesterolemic type 2 diabetic patients.The clinical trial repoeted on Journal of
Medicinal Plants showed the significant lowering effect of artichoke leaf extract on the blood
levels of total cholesterol and LDL cholesterol without any significant effects on the blood levels
of fasting glucose, postprandial glucose, glycosylated hemoglobin, other lipids, SGOT, SGPT and
creatinine (P>0.05) compared with placebo at the endpoint and any adverse effects.Such results
suggest that fiber-free artichoke extract may be a safe anti-hypercholesterolemic agent but does
not improve glycemic control in hypercholesterolemic type 2 diabetic patients, suggesting the
involvement of fibers in the anti-hyperglycemic effect of artichoke.
Anticancer
The apoptotic and cytotoxic activity of artichoke has been studied .One investigation was focus on
artichike activity against DLD1 colorectal cancer cells .The report on Asian Pacific Journal of
Cancer Prevention showed hexane extracts from wild and cultivated artichoke were all found to
induce pro-apoptotic (BAX) gene expression and a cell cycle inhibitor (p21) .In contrast,
anti-apoptotic BCL-2 gene expression was reduced compared to the control group. In addition
DNA fragmentation results demonstrated DLD1 cell death via apoptosis.
Applications
In various pharmacological tests artichoke leaf extracts have shown hypotensive ,
anti-hyperlipidemic ,anti-hyperglycemic, choleretic activity ,hepatoprotective and prebiotic
effects . In addition, artichoke leaf extracts contain compounds with antifungal and antimicrobial
activities.
Recent studies indicate that artichoke leaf extracts may also have therapeutic potential for
cardiovascular disease. The plant contains multiple compounds with high antioxidant properties .
Extracts of the leaves and root are helpful in arteriosclerosis, jaundice, dyspepsia, liver
insufficiency, chronic albuminuria, and postoperative anemia, reduces cholesterol blood levels. In
some countries, considered an aphrodisiac.
