• Campesterol / Antiangiogenic
/ Anticancer: Campesterol, a plant sterol , known for
cholesterol lowering and anticarcinogenic effects. Isolated from C coronarium,
the study results supported its potential antiangiogenic action through
inhibition of endothelial cell proliferation and capillary differentiation. (1)
• Pyrethrosin Derivatives / Cytotoxic: Study yielded three sesquiterpene lactones. Two compounds showed cytotoxic activities against human cancer lines.
• Heterocycle / Hypolipidemic:
Study of methanol extract of aerial
parts of CC isolated one new heterocycle, 5, 5'-dibuthoxy-2,2'-bofuran and five known compounds: methyl trans-ferulate, prunasin, sambunigrin, pterolactam and adenosin. Results showed
inhibition of low-density lipoprotein (LDL) oxidation.
Study results on the aqueous
extracts of C. coronarium suggest hypoglycemic effect in diabetic rats
equivalent to that of glibenclamide.
Study of extracts from
flower and leaves of C coronarium showed insecticidal activity. Sesquiterpene
lactones, toxic to insects have been isolated from the flower head of

Alternaria sp, Aspergillus flavus and Phthium ultimum.
yielded compounds emodin, chrysopanol, chrysazin, quercetin and isoquercetin,
high amounts of vitamin C and carotenoids – all together suggesting
possible usefulness in cardiovascular preventive therapy.
• Antijuvenile Hormone / Insecticidal: Studies confirm the antihormone as acetylenic sulfoxide, compound C. Biological assays indicate significant insecticidal activity in a number of fractions. Anti-juvenile hormone activity was not expressed until the pure major constituents were tested individually. (8)
• Antimicrobial : Study investigated the antimicrobial activity of four Tunisian Chrysanthemum species. Findings showed that some Chrysanthemum extracts exhibited antimicrobial and/or anti-HSV activities. (9)
• Nematicidal : Study showed significant reduction nematode infection of tomato roots and improved plant-top fresh weight, both in the greenhouse and in microplots. Only mature plants, in their flowering stage, exhibited nematode control activity. The green plant parts were more effective than the flowers. (12)
• Insecticidal : Study showed the flower extract to have insecticidal activity on the cotton leaf worm Spodoptera littoralis. Major constituents were 3-dihydro-methylene-2- (3H) furanone (17.8%), jasmolin I (15.6%), carveol 1 (13.6%), phosphoric acid, tributyl ester (11.4%) and cinerin II (11.1%), while those of chloroform fraction were 5-hydroxy-3 methyl-1H-pyrazole (42.7%) and carveol 1(24.8%). Because of its safety profile, it presents as a promising alternative to integrated pest management. (13)
• Hepatoprotective / Antioxidant / Fertility Effects: Study evaluated the biologic activity of an ethanol extract of C. coronarium and its fractions. Results showed antioxidant oxidant activity, highest in the ethyl acetate fraction. It also showed hepatoprotective activity and improvement of fertility. (14)
• Biosorption of Cadmium (II) and Cobalt (II): Study reports on the removal ability of cadium (II) and cobalt (II) ions from aqueous solution by natural and low cost biosorbents developed from Diplotaxis harra and Glebionis coronaria. Results showed the biosorption process to be very rapid with the biosorption yield increasing with increase in biosorbent dosage. (17)
• Antiproliferative / Antimicrobial / Antioxidant / Acetylcholinesterase Inhibition / Essential Oil: Study of essential oil for antioxidant activity by DPPH method showed moderate radical scavenging activity. The oil also exhibited cholinesterase inhibitory activity. Antibacterial activity was more pronounced against Gram-positive strains. On in vitro antiproliferative evaluation, EO demonstrated variable activities towards different human cancer cell lines, of which colon cancer was the most sensitive. (19)
• Anti-Inflammatory: In a study of eight selected plant extracts, Chrysanthemum coronarium was one of seven extracts that showed promising anti-inflammatory property. Extracts decreased NO and TNFa synthesis in cells of monocyte origin activated with LPS. The extracts decreased cytokine or LPS-stimulated iNOS mRNA levels in both cell types. (22)
