Analysis of the Essential Oils of Chamaemelum fuscatum (Brot.) Vasc. from Spain as a Contribution to Reinforce Its Ethnobotanical Use

Abstract

Chamaemelum fuscatum (Brot.) Vasc. is a south west Iberian chamomile that has been traditionally used as folk medicine in its natural distribution area but currently it is underestimated regarding its biological activities. For this reason, it is proposed in this paper to get insight into the scientific validation of the traditional knowledge of this plant with the aim of taking advantage of its anti-inflammatory, gastroprotective and antinociceptive activities, among others. To this aim, the chemical composition of the essential oil from the whole plant, the flowers and the green parts of this plant has been evaluated by gas chromatography–mass spectrometry (GC–MS). Plant materials were collected in Badajoz (Spain). A total of 61 components including monoterpenoids, sesquiterpenoids and aliphatic esters were identified. (E)-2-Methyl-2-butenyl methacrylate (27.57%–18.53%) and 2-methylallyl isobutyrate (9.79%–7.51%) were the most abundant compounds in the essential oils of flowers and of the whole plant, whereas α-curcumene, trans-pinocarveol, α-bergamotene and pinocarvone were the major terpenoids irrespective of the plant part considered. Certain compounds showing a relative high abundance as isobutyl methacrylate, isoamyl butyrate, α-bergamotene and pinocarvone were identified for the first time in this species. Finally, we have reviewed the bioactivity of several compounds to relate the ethnobotanical use of this plant in Spain with its volatile profile. This work is a preliminary contribution to reinforce the use to this Mediterranean endemic plant as a natural source of bioactives.

“…Afzelin), were isolated and identified in smaller proportions in the same study. In another study, Rasoanaivo et al [ 72 ] found higher trans-pinocarveol at 35.6–36.3% and pinocarvone at 19.8–20.0% in a species variety, Myrothamnus moschatus (Baillon) Niedenzu, endemic to Madagascar. The presence of 85 compounds, namely pinocarvone (11.13%), trans-pinocarveol (19.57%), limonene (6.09%), trans-p-menth-1-(7)-8-diene-2-ol (7.43% and cis-p-menth-1-(7)-8-diene-2-ol (6.76%), and others, representing 87.79% of the essential oil from hydro-distilled above-ground M. flabellifolius material, was reported [ 8 ].…”

“…Myrothamus flabellifolius hydro-distillation produced 0.04% wet weight of essential oil [ 8 ]. Three-hour steam distillation of freshly collected aerial parts weighing 6 kg yielded 0.73% and 0.67% ( w / w ) essential oil from M. moschatus, commonly found in Madagascar [ 6 , 11 , 72 ]. Chaturvedi et al [ 11 ] found the following extract yields using different extraction methods: 14 (100% hexane), 32 (100% chloroform), 40 (100% methanol), 40 (70% methanol/water), and 48% (70% Ethanol/water) from sun-dried M. flabellifolius, collected in Botswana.…”

“…On the other side, 2-methyl butyl isovalerate was the only identified oxygenated monoterpene, with a relative concentration of 10.43%. Isovalerate derivatives have been described in the EOs of several plants such as Eucalyptus brockwayii [37], Algerian Daucus gracilis [38], and Chamaemelum fuscatum [39]. Sesquiterpenes made up a relative concentration of 15.77% of the total oil mass.…”

Forest, Foods, and Nutrition

“…The beneficial potential of medicinal plants and herbs has been investigated in different papers [9][10][11][12]. Functionally, extracts and biologically active components [13][14][15][16][17][18] from forest products are experiencing great interest for both research and potential application in nutraceutical, pharmaceutical, and cosmetic fields [19,20]. Fernández-Cervantes et al [20] studied the essential oils of Chamaemelum fuscatum (Brot.)…”
