Carthamus tinctorius
L. commonly known
as Safflower or false saffron is a thistle like, self-
compatible, annual, diploid (2
=24) herbaceous crop
that thrives in hot and dry climates and is believed to
have been domesticated somewhere in the Fertile
Crescent region over 4,000 years ago.
It belongs to Asteraceae family in the order of
Asterales that contains about 22,750 genera and more
than 1,620 species.
species probably
originate from Southern Asia and is known to have been
cultivated in China, India, Iran and Egypt almost from
prehistoric times. During middle ages it was cultivated
in Italy, France, and Spain, and was introduced into
United States in 1925 from the Mediterranean region.
has been known as "Golrang" in Iran. It is
grown for the red/orange pigment in the flower petals
which is used for coloring rice and bread, and for dyeing
cloth. After synthetic aniline dyes took over this market in
the 1800's the crop was grown as an oilseed.
is described as a bushy, herbaceous
annual possessing several branches, which are
categorized as primary, secondary, and tertiary,
with each terminating into a globular structure called
capitulum. Stem and branches are encompassed
with leaves having numerous spines. Safflower is
mainly grown under dry land conditions as an oilseed
crop. It produces white, shiny, and smooth seeds
(fruits) called achenes. They may be with or without
pappus (tufts of hair present on the seed) and are four
sided, having thick pericarp. Each branch produces a
globular flower capitulum which is enclosed by tightly
attached bracts. Safflower has a taproot system that
elongates to 2–3 m in soils with adequate depth. The
deep root system in safflower helps to extract the
water and a nutrient from much deeper layers of soil,
compared to other crop plants, and thus makes it an
ideal plant for rain-fed cropping systems.
This plant is cultivated mainly for its seed, which
is used as edible oil and as birdseed. This crop was
also grown for its flowers, used for coloring and
flavoring foods and making dyes. It has become an
increasingly important crop in some parts of the world
including Turkey and Iran due to the rich content and
high nutritional value of its edible oil.
It contains a
high amount of polyunsaturated fatty acid linoleic acid
(70%) and monounsaturated oleic acid (10%) with
small amounts of stearic acid.

Potential of
in Phytotherapies
Anti-inflammatory and Analgesic Properties
Although a number of steroidal or non-steroidal
anti-inflammatory drugs have been developed,
researchers are changing their focus to natural
products to develop new anti-inflammatory agents due
to the side-effects of chemical drugs.
As a result,
the search for other alternatives seems necessary and
are an open door for new and
effective compounds. Many cells and mediators are
involved in proceeding inflammation. For example,
macrophages are representative inflammatory cells
involved in acute or chronic inflammatory responses
by over-production of pro-inflammatory cytokines [for
example, tumor necrosis factor (TNF)-α, interleukin
(IL)-1b and granulocyte/macrophage colony stimulating
factor (GMCSF)] and inflammatory mediators.
The intraperitoneal injection of safflow yellow A
at doses of 50–100 mg/kg in mice showed sustained
analgesic action. This compound also inhibited
formaldehyde-induced foot swelling, histamine-
stimulated capillary permeability, and formation of
cotton ball granuloma in rats. The central inhibition
induced by barbital of chloralin mice was markedly
enhanced by safflor yellow A. The coramine-induced
convulsions and death were markedly reduced.
Anti-inflammatory action of methanol extract of
(MEC) involves in heme oxygenase-1
(H0-1) induction. The results show that MEC induces
HO-1 expression via Nrf2 translocation and inhibits
nuclear factor kappa B (NF-κB) activity, which may
be responsible for anti-inflammatory action.
The flavone luteolin and its glucopyranoside
such as luteolin 7-O-beta-D-glucopyranoside and
have been reported to exert anti-inflammatory effects
in vitro
in vivo
and several works have shown
that these compounds which are rich in
flowers inhibited NF-κB activity at concentrations in
the low micromolar range.
Flowers of
possess central analgesic
activity (500 mg/kg) and potentially may lead to the
development of morphine-like substances devoid of the
side effects of morphine and related drugs.
Anticoagulant Effects
The brain is susceptible to ischemia-induced
damage followed by thrombotic block. Generally,
cerebral ischemia is characterized by the state of
hypercoagulability and hyperviscosity in circulation,
which is prone to form thrombosis.
Studies have
demonstrated that Hydroxysafflor yellow A (HSYA)
contained in
flowers markedly extended
coagulation time in mice, which raises the possibility
that it might exert therapeutic actives on cerebral
ischemia induced by thrombosis. Followed researches
have shown that HSYA dose dependently improved
the neurological deficit scores and reduced the cerebral
infarct area and it bore a similarity in potency of the
therapeutic effects on focal cerebral ischemia to
nimodipine as the standard drug. The inhibition rates of
thrombosis formation by HSYA at the doses of 1.5, 3.0
and 6.0 mg/kg, at 30 min after the onset of ischemia
were 20.3%, 43.6% and 54.2%, respectively. Inhibitory
activities of HSYA were observed on adenosine
diphosphate (ADP)-induced platelets aggregation
in a dose-dependent manner, and the maximum
inhibitory aggregation rate of HSYA was 41.8%. Blood
rheological parameters were markedly improved by
HSYA, such as whole blood viscosity, plasma viscosity,
deformability and aggregation of erythrocyte, but no
significant effect of HSYA on hematocrit was found.
The underlying mechanisms exerted by HSYA might be
involved in its inhibitory effects on thrombosis formation
and platelet aggregation as well as its beneficial action
on regulation of prostacyclin/thromboxane (PGI2/TXA2)
and blood rheological changes in rats.
is commonly used in Chinese medicine
to promote blood circulation and remove blood stasis.
Blood stasis, i.e. the decrease of blood flow velocity,
Chin J Integr Med 2013 Feb;19(2):153-159
indicates hemorheological abnormalities. Studies
have been shown the effects of carthamins yellow
contained in safflower flowers on blood stasis. Results
have demonstrated that this compound significantly
decreased the whole blood viscosity, plasma viscosity
and erythrocyte aggregation index which were increased
in blood stasis. Hematocrit and platelet aggregation were
reduced while the prothrombin time was delayed. So
this natural food coloring agent could be a great value in
the prevention of hemorheological disorders-associated
diseases in at risk patients.
Antioxidant Activity
An antioxidant is defined as any substance
that, when present at low concentrations compared
to those of an oxidizable substrate, significantly
delays or prevents oxidation of that substrate.
Antioxidants are of interest to biologists and clinicians
because they help to protect the human body against
damages induced by reactive free radicals generated
in atherosclerosis, ischemic heart disease, cancer,
Alzheimer's disease, Parkinson's disease and even
in aging process.
There are many evidences that
natural products and their derivatives have efficient
antioxidative characteristics, consequently linked
to anticancer, hypolipidemic, antiaging and anti-
inflammatory activities.
Antioxidative capacities of

) value for Ferric reduction assay was determined
as 1,140.5 μmol/g.
Total phenolic content from
the flowers was determined as 2.12 and 1.32 g/100 g
for methanolic and aqueous extracts respectively.
As the flowers contained high phenolic compounds
including it confirmed that they have an important role
in antioxidant activities.
Ethanol extract of safflower seeds inhibited low
density lipoprotein (LDL) oxidation induced
in vitro
by an
azo-containing free-radical initiator V70 or copper ions.
Two serotonin derivatives, N-(p-coumaroyl) serotonin,
and N-feruloylserotonin and their glucoside derivatives
were identified as the major phenolic and active
constituents of the extract. It was demonstrate that these
serotonin derivatives were absorbed into circulation and
attenuate atherosclerotic lesion development possibly
because of the inhibition of oxidized LDL formation
through their strong antioxidative activity.
Effects on Osteoporosis
Osteoporosis can result from such conditions
as senility, post menopause, calcium deficiency and
immobilization as well as endocrinological and nutritional
changes. Increased bone loss in postmenopausal
osteoporosis is suggested to result from estrogen
deficiency. Estrogen deficiency and calcium deficiency
are reported to be additive factors in the genesis of
Safflower seed oil has high linoleic acid level,
which possesses anti-inflammatory activity in bone by
moderating prostanoid formation, correcting bone loss
due to ovariectomy and increasing intestinal calcium
Safflower seed powder contains many minerals
especially calcium, magnesium and potassium, and is
effective in preventing the osteoporotic process caused
by bilateral ovariectomy in rat model.
Safflower seed
powder effectively prevented reduction of cortical bone
width and bone loss in the established osteoporotic rat
resulting from estrogen deficiency. It was demonstrated
that the safflower seed powder effectively inhibited
bone loss associated with estrogen deficiency in rats.
Also, oral administration of safflower seed oil at
a dose of 1 mL/kg to ovariectomized rats for 30 days
showed positive changes compared to the vehicle
treated ovariectomized control rats. Safflower seeds
have shown a possible role in the improvement of
ovariectomy induced osteoporosis in rats.
The aqueous extract of safflower seed significantly
accelerated rates of osteoblast differentiation in the
experimental group as compared to the control group in
murine osteoblastic cells of the MC3T3-E1 line cultured
on modified Eagle's minimum essential medium.
Phytoestrogen rich safflower seeds demonstrated a
protective effect on bone loss caused by estrogen
deficiency, without substantial effect on the uterus. The
beneficial effect of safflower seeds may be mediated,
at least in part, by the stimulating effect of polyphenolic
compounds on proliferation of osteoblasts.

bone resorption by inhibition of phosphorylation
of peptide substrates. HHI dose-dependently reduced
the hypercalcemia induced in mice by IL-1b and partly
prevented bone loss and microarchitectural changes in
young ovariectomized rats, showing that the protective
effect on bone was exerted via the inhibition of bone
resorption. These results indicate that the synergy
between IL-b, TNF-α, IL-6 on PGE2 production is
due to an enhanced gene expression of COX-2 and
that tyrosine kinase (s) are involved in the signal
transduction of COX-2 in mouse calvarial osteoblasts.
Hepatoprotective Activity
It has been shown that both methanolic extract

the toxic effect of CCl
, similar to the standard silymarin
in the levels of liver function serum markers, aspartate
aminotransferase (AST), alanine aminotransferase
(ALT) and alkaline phosphatase (ALP), total bilirubin
and increase in the protein synthesis. The percentage
of protection was greater in dehydroabietylamine at
50 mg/kg which is comparable to the reference drug
silymarin (100 mg/kg).
The protection against the injurious effects of
carbon tetrachloride may be due to the inhibitory
effects on cytochrome P450 resulting in the hindrance
of the formation of hepatotoxic free radicals.
The rats treated with methanolic extract and
dehydroabietylamine along with toxicant showed signs
of protection against the toxicants.
Powdered safflower seed lowered the plasma
cholesterol concentration in high-fat and high-
cholesterol fed rats. Safflower seed preparations
including seed powder, ethanol extract and aqueous
extracts of the seeds significantly lowered the plasma
cholesterol and triglyceride concentrations. The
hepatic total cholesterol and hepatic triglyceride
contents were significantly lowered. The hepatic
3-hydroxy-3-methylglutaryl-coenzyme A (HMG-
CoA) reductase activities were significantly high. The
hepatic acylcoenzyme A cholesterol acyltransferase
(ACAT) activities were significantly low. Therefore,
supplementation of safflower seeds is effective
in improving the atherogenic risk factors in high-
Animals treated with 2%-cholesterol diet and
dichloromethane extracts of the seeds for a week
exhibited decreased body weight. After treatment
for 14 and 30 days, a significant reduction in total
cholesterol and total cholesterol/high density lipoprotein
(HDL)-cholesterol and a significant induction in HDL-
cholesterol were observed in the hypercholesterolemic
rats treated with the dichloromethane extract.
The dichloromethane extract can reduce the total
cholesterol/HDL-cholesterol of hyperlipidemic rats.
Antidiabetic Effects
Safflower is useful for treatment of diabetes and
its complications. The flower aqueous extract can
reverse the metabolic disorders occurring in alloxan
induced diabetes. Considering these effects on these
lipid components, it can be assumed as a potential
hypolipidemic agent, which will be a great advantage
both in diabetic condition as well as the associated
atherosclerosis or hyperlipidemic conditions.
flowers regenerates and restorates
of Langerhan islets, thus the insulin level would be
elevated. Safflower enhances the secretion of insulin
from the beta cells of the islets of Langerhans. Further,
it has an ability to restore the protein breakdown and
enhance the glycogenesis process in the liver of
diabetic rats.
Serotonin derivatives such as N-p-coumaroyl
serotonin and N-feruloyl serotonin isolated from
seeds were active as α-glucosidase
inhibitors. These compounds showed a potent
inhibitory activity, IC
values were calculated as
47.2 μmol/L and 99.8 μmol/L while that of the
reference drugs acarbose and 1-deoxynojirimycin
were evaluated as 907.5 μmol/L and 278.0 μmol/L,
respectively. These results are helpful for the proper
use of safflower seed as a traditional medicine for
the treatment of diabetes; moreover, it could serve to
develop medicinal preparations as supplements and
functional foods for diabetes.

The objective of this review has been to show
the recent advances in the exploration of
as phytotherapy and to illustrate its potential as a
therapeutic agent. With the current information, it is
evident that
has pharmacological functions
including antioxidant, anti-inflammation, analgesic,
antidiabetic, hepatoprotective and antihperlipidemic
activities, among others. As the current information
shows, it is also possible that furanocoumarins might
be useful in the development of new drugs to treat
various diseases. However, the present results suggest
a possibility that serotonin derivatives and flavonoids
can be further developed as a potential disease-
curing remedy. It must be kept in mind that clinicians
should remain cautious until more definitive studies
demonstrate the quality and efficacy of
For these reasons, extensive pharmacological and
chemical experiments, together with human metabolism
will be a focus for future studies. Last but not the least,
this review emphasizes the potential of
to be employed in new therapeutic drugs and provide
the basis for future research on the application of
transitional medicinal plants.

... Herbal medicines, which contain various phytochemicals such as polyphenols, vitamins, and flavonoids have been widely used as natural antioxidants to inhibit oxidative stress [5]. The seed of Carthamus tinctorius L. (CTS) has been used for studying pharmacological activities, such as anti-inflammation, antioxidation, and anti-diabetes [6,7]. Taraxacum coreanum (TC) has been used for the treatment of inflammatory diseases, such as rheumatic disease and gastritis, for a long time [8][9][10]. ...
... CTS is widely used as a raw material in edible oil and has high nutritional value, containing approximately 70% linoleic acid [7]. Moreover, phenolic compounds including N-feruloyl serotonin, N-(p-coumaroyl) serotonin, luteolin, and acacetin have been isolated from the ethyl acetate fraction of the CTS extracts [7,23]. ...

Oxidative stress is closely associated with the pathology of neurodegenerative diseases. The seeds of Carthamus tinctorius L. (CTS) and Taraxacum coreanum (TC) are reported as herbal medicines for neuroprotection. This study investigated the protective effect of CTS, TC, and their combination against oxidative stress induced by H2O2 in SH-SY5Y cells. The CTS and TC combination dose-dependently increased DPPH and ·OH radical scavenging activities compared with non-combination. The combination showed a higher increased cell survival rate in H2O2-stimulated SH-SY5Y cells than CTS or TC. Moreover, CTS, TC, and their combination-treated cells reduced LDH release and apoptotic cells. CTS, TC, and their combination also inhibited NO and ROS generation. Further, the combination of up-regulated antioxidant enzymes (superoxide dismutase and glutathione peroxidase) and Bcl-2 protein expressions and down-regulated Bax expression. These findings suggest that the combination of CTS and TC may be beneficial to prevent and treat oxidative stress-mediated neurodegenerative diseases.

Hydroxysafflor yellow A is extracted from Carthamus tinctorius L., Asteraceae, and has extensive pharmacological properties. In this study, interleukin-1 beta was used to establish the osteoarthritis model in vitro , and the impacts of hydroxysafflor yellow A on the cell model were analyzed. CCK8 was used to measure cell viability, and flow cytometry was used to evaluate apoptosis and reactive oxygen species. An enzyme-linked immunosorbent assay was performed to calculate the release of inflammatory cytokines and oxidative stress index. Western blotting was performed to measure the expression of collagen-related proteins. The protein levels in the HIF-1α/JAK/STAT3 signaling pathway were also measured. The results showed that hydroxysafflor yellow A promoted cell viability and inhibited apoptosis and oxidative stress. In addition, quinochalcone C -glycoside upregulated the expression of collagen II and Sry-related HMG box-9, while downregulating the expression of matrix metalloproteinase-13. Interleukin-1 beta induced high levels of interleukin-6 and tumor necrosis factor-α that were inhibited by hydroxysafflor yellow A. Meanwhile, hydroxysafflor yellow A inhibited the interleukin-1 beta–induced high levels of reactive oxygen species and malondialdehyde and enhanced the interleukin-1 beta–induced low levels of superoxide dismutase and glutathione peroxidase. Furthermore, hydroxysafflor yellow A downregulated the mRNA expression of HIF-1α, JAK, STAT3, and interleukin-6 as well as the protein expression of HIF-1α, p-JAK, and p-STAT3. The results suggest that hydroxysafflor yellow A inhibited the JAK/STAT3 signaling pathways by inhibiting HIF-1α. Therefore, hydroxysafflor yellow A regulates the inflammatory response and oxidative stress in vitro . Graphical abstract

The Carthamus tinctorius, commonly known as safflower, is an annual plant with numerous branches and thorns from the Asteraceae family. For this experiment, three treatments were applied to the pots: humic acid, spirulina micro-algae, and a mixture of both to analyze their bioactivation effects. These treatments were applied three times per week over the course of two weeks, with irrigation taking place every other day. The wet weight of the aerial parts of the harvested plants was measured and placed in liquid nitrogen, then stored in a freezer. Chlorophyll, carotenoids, proline, protein, phenol, antioxidants, and malondialdehyde were measured. The results show that several bioactivators significantly increased the growth, chlorophyll, carotenoids, protein, and proline of safflower plants when compared to the control. The three treatments reduced the antioxidant and malondialdehyde content significantly. In contrast to the control condition, the mixture of humic acid and spirulina microalgae, as well as humic acid alone, decreased the phenolic content. The findings demonstrated that humic acid and spirulina microalgae can serve as positive plant bioactivators for safflower by boosting its growth and reducing stress.
... It is mainly used in traditional medicine for amenorrhea, dysmenorrhea and lochia. Recent studies have showed that flavonoids are the main bioactive components in safflower, which have anti-inflammatory, anti-oxidant, anti-apoptosis, anti-cerebral ischemic reperfusion injury and protection of cardiovascular and cerebrovascular effects (Asgarpanah and Kazemivash, 2013). However, there are relatively few reports on the pharmacodynamics of NAG. ...

GuHong injection is composed of safflower and N -acetyl-L-glutamine. It is widely used in clinical for cerebrovascular diseases, such as ischemic stroke and related diseases. The objective of this review is to comprehensively summarize the most recent information related to GuHong in the treatment of stroke, including chemical composition, clinical studies, potential pharmacological mechanisms and pharmacokinetics. Additionally, it examines possible scientific gaps in current study and aims to provide a reliable reference for future GuHong studies. The systematic review reveals that the chemical composition of safflower in GuHong is more than 300 chemical components in five categories. GuHong injection is primarily used in clinical applications for acute ischemic stroke and related diseases. Pharmacological investigations have indicated that GuHong acts in the early and recovery stages of ischemic stroke by anti-inflammatory, anti-oxidative stress, anti-coagulation, neuroprotective and anti-apoptotic mechanisms simultaneously. Pharmacokinetic studies found that the main exposed substances in rat plasma after GuHong administration are hydroxysafflor yellow A and N -acetyl-L-glutamine, and N -acetyl-L-glutamine could exert its pharmacological effect across the blood-brain barrier. As a combination of Chinese herb and chemical drug, GuHong injection has great value in drug research and clinical treatment, especially for ischemic stroke disease. This article represents a comprehensive and systematic review of existing studies on GuHong injection, including chemical composition, pharmacological mechanism, and pharmacokinetics, which provides reference significance for the clinical treatment of ischemic stroke with GuHong, as well as provides guidance for further study.
Inflammation is a part of the biological response of body tissues against harmful stimuli, such as damaged cells, pathogens, irradiations, and toxic compounds. Numerous treatments, including anti-inflammatory drugs that treat the condition of inflammation, are available for its management. Because of the severe adverse effects associated with synthetic medications, phytotherapy may be a promising and effective approach to treating inflammation. The therapeutic potential of herbs is due to their capacity to target a variety of inflammatory mediators, including chemokines, cytokines, nitric oxide, lipoxygenase, nuclear factor kappa-B, and arachidonic acid. Furthermore, nanomedicine may be a valuable and effective formulation approach for overcoming the drawbacks of phytoconstituents, such as their low bioavailability, high first-pass metabolism, and poor stability. The current manuscript provides a thorough description of many phytoconstituents and herbal plants that have great potential for treating inflammation-related diseases, as well as information on their limitations, drug formulations, and regulatory issues.
Background Skin aging is a natural process that occurs because of oxidative stress. Facial skin aging is often concerning for individuals due to the exposure of the face. Objectives To assess and compare the effects of two anti‐aging facial serums on the following characteristics associated with facial skin aging: fine lines/wrinkles, age spots, firmness, elasticity, texture, radiance, tone, lifting, clarity, and complexion. Methods A 24‐week, double‐blind controlled study was conducted on 130 participants who were randomized into two groups: facial serum with Liposomal Blend and facial serum without Liposomal Blend. Clinical evaluations (Visual Analog Scale) and instrumental evaluations (Cutometer, SIAscope, and Clarity Pro image analysis) were performed at weeks 0 (baseline), 2, 4, 8, 12, and 24 to assess for changes in skin aging characteristics. Results A total of 123 participants completed the study; participants that used the facial serum with Liposomal Blend had significantly greater improvements in skin aging characteristics compared to those that used the facial serum without Liposomal Blend. This study shows that Liposomal Blend is a vehicle with the ability to enhance the anti‐aging properties of the ingredients within the facial serum by facilitating its delivery into the underlying layers of the skin. Higher concentration of ingredients at the site of action could potentially lead to greater damage repair and improvements in signs of facial skin aging. Conclusion By using Liposomal Blend, practitioners and pharmacists could potentially improve the delivery of the ingredients within their formulations into the skin, which may lead to increased treatment efficacy.

To explore the complete biosynthesis process of flavonoid glycosides in safflower, specifically the key glycosyltransferase that might be involved, as well as to develop an efficient biocatalyst to synthesize flavonoid glycosides, a glycosyltransferase CtUGT4, with flavonoid-O-glycosyltransferase activity, was identified in safflower. The fusion protein of CtUGT4 was heterologously expressed in Escherichia coli, and the target protein was purified. The recombinant protein can catalyze quercetin to form quercetin-7-O-glucoside, and kaempferol to form kaempferol-3-O in vitro, and a series of flavones, flavonols, dihydroflavones, chalcones, and chalcone glycosides were used as substrates to generate new products. CtUGT4 was expressed in the tobacco transient expression system, and the enzyme activity results showed that it could catalyze kaempferol to kaempferol-3-O-glucoside, and quercetin to quercetin-3-O-glucoside. After overexpressing CtUGT4 in safflower, the content of quercetin-3-O-rutinoside in the safflower florets increased significantly, and the content of quercetin-3-O-glucoside also tended to increase, which preliminarily confirmed the function of CtUGT4 flavonoid-O-glycosyltransferase. This work demonstrated the flavonoid-O-glycosyltransferase function of safflower CtUGT4 and showed differences in the affinity for different flavonoid substrates and the regioselectivity of catalytic sites in safflower, both in vivo and in vitro, providing clues for further research regarding the function of UGT genes, as well as new ideas for the cultivation engineering of the directional improvement of effective metabolites in safflower.

The crude drug ''kouka,'' dried flower petals of Carthamus tinctorius Linne (Compositae), has been used for women's diseases in China and Japan. In the present study, the pharmacological effect of C. tinctorius was examined by using mice of ddY strain. C. tinctorius extract decreased the revolution activity in a wheel cage, suppressed the acetic acid-induced writhing, prolonged the hexobarbital-induced hypnosis period, delayed the death caused by pentylenetetrazole and inhibited the carrageenin-induced hind paw edema in mice.
The antimutagenicity of the Citrus flavonoids naringin, hesperidin, nobiletin, and tangeretin against the mutagens benzo[a]pyrene, 2-aminofluorene, quercetin, and nitroquinoline N-oxide was investigated in the Salmonella/microsome assay. Naringin and hesperidin showed a weak antimutagenic activity against benzo[a]pyrene. Tangeretin was antimutagenic against all indirectly-acting mutagens tested, but in general a large molar excess was necessary. Liquid preincubation increased the antimutagenicity of tangeretin against 2-aminofluorene. Nobi-letin acted as an antimutagen against benzo[a]pyrene, but it enhanced the mutagenicity of 2-aminofluorene. However, in a liquid preincubation assay nobiletin also exhibited antimuta-genicity against 2-aminofluorene. Both tangeretin and nobiletin inhibited the mutagenicity of quercetin. Quercetin itself acted as an antimutagen against 2-aminofluorene in a Salmonella strain (TA1538) where its mutagenicity was not expressed. Quercetin should not merely be regarded as a genotoxic risk factor in the human diet, since its mutagenicity may be inhibited by accompanying compounds including other flavonoids, and since quer-cetin itself also exhibits an antimutagenic action. Because of the antimutagenic properties the Citrus flavonoids tested, especially tangeretin and nobiletin, might play a role in the chemopreven-tion of cancer.
