Rossi T, Melegari M, Bianchi A, Albasini A, Vampa G. Sedative, anti-inflammatory and anti-diuretic effects induced in rats by essential oils of varieties of Anthemis nobilis: a comparative study. Pharmacol Res Commun. 1988 Dec;20 Suppl 5:71-4. doi: 10.1016/s0031-6989(88)80844-0. 

Abstract. The pharmacological properties of essential oils obtained from two varieties of Anthemis nobilis was studied. The two varieties, named "white-headed" or double flowered and "yellow-headed", present considerable morphological differences and yield essential oils with different composition. These essential oils proved to possess interesting anti-inflammatory and sedative properties, especially that derived from the "White-headed" variety.

De Mieri M, Monteleone G, Ismajili I, Kaiser M, Hamburger M. Antiprotozoal Activity-Based Profiling of a Dichloromethane Extract from Anthemis nobilis Flowers. J Nat Prod. 2017 Feb 24;80(2):459-470. doi: 10.1021/acs.jnatprod.6b00980. 

Abstract. A dichlomethane extract of Anthemis nobilis flower cones showed promising in vitro antiprotozoal activity against Trypanosoma brucei rhodesiense and Leishmania donovani, with IC50 values of 1.43 ± 0.50 and 1.40 ± 0.07 μg/mL, respectively. A comprehensive profiling of the most active fractions afforded 19 sesquiterpene lactones, including 15 germacranolides, two seco-sesquiterpenes, one guaianolide sesquiterpene lactone, and one cadinane acid. Of these, 13 compounds were found to be new natural products. The compounds were characterized by extensive spectroscopic data analysis (1D and 2D NMR, HRMS, circular dichroism) and computational methods, and their in vitro antiprotozoal activity was evaluated. The furanoheliangolide derivative 15 showed high potency and selectivity in vitro against T. b. rhodesiense bloodstream forms (IC50 0.08 ± 0.01 μM; SI 63). In silico calculations were consistent with the drug-like properties of 15.

Hydroperoxides from the blossoms of Roman camomile, Anthemis nobilis L. Arch Pharm (Weinheim). 1989 Nov;322(11):821-6. German. doi: 10.1002/ardp.19893221109. 

Abstract. From the ethanol extract of the blossoms of Anthemis nobilis L. (syn. Chamaemelum nobile L.), six new hydroperoxides (1-6) were isolated, besides the known 1 beta-hydroperoxyisonobilin (7). The structures were elucidated by spectroscopic methods and in some cases ascertained by synthesis. Compounds 2 and 3 show a medium antibacterial activity.

Grabarczyk H, Drozdz B, Hladoń B, Wojciechowska J. Sesquiterpene lactones. Part XV. New cytostatic active sesquiterpene lactone from herb of Anthemis nobilis L. Pol J Pharmacol Pharm. 1977 Jul-Aug;29(4):419-23.

Abstract. From fresh and dried herb (without inflorescences) of Anthemis nobilis L. a new sesquiterpene lactone C20H26O6 was isolated. This compound showed a cytotoxic activity at a level of ED50 HeLa -- 0-56 microgram/ml (1-5 x 10(-6) M), and ED50 KB -- 1.23 microgram/ml (3-5 x 10(-6) M), what qualifies it for further in vivo studies.

SADIKI, F. Z., & El Idrissi, M. (2019). Chemical composition of essential oil of Anthemis nobilis L. flowers from Morocco. Applied Journal of Environmental Engineering Science, 5(4), 5-4.

Abstract. In this work, we studied the chemical composition of the essential oil extracted from dried flowers of Anthemis nobilis L. harvested from the region of Fez (Morocco). The extraction of the essential oil was carried out by hydrodistillation. The composition of essential oil was analyzed by gas chromatography coupled with mass spectrometry. The results obtained indicate that the extraction yield of the essential oil is 0.33%. Qualitative and qualitative analysis identified 43 constituents representing 88.63% of the essential oil. The major compounds were: En-yn-dicycloether (20.90%), β-Caryophyllene (19.17%) and Aristolene epoxide (7.39 %).
