Partial chemical composition and antimicrobial activity of <i>Daucus crinitus</i> Desf. extracts

Abstract

The chemical composition of fatty acids and the unsaponifiable fraction of the roots, leaves and stems from <i>Daucus crinitus</i> Desf. were, determined using gas chromatography (GC) and gas chromatography-Mass Spectrometry (GC-MS). The fatty acid fractions of different organs (leaves, stems and roots) were characterized by lauric acid (17.9, 17.5 and 18.1 % respectively) and other long chain fatty acids (until C₂₂). Qualitative and quantitative differences were reported between the unsaponifiable fractions of different organs from <i>D. crinitus</i>. The unsaponifiable fractions of the leaves, roots and stem showed high amounts of aliphatic components (83.4%, 87.2% and 91.4%, respectively). The monoterpen, diterpen and sesquiterpen components were only present in small percentages. The antimicrobial properties of the <i>D. critinus</i> extracts were tested on four different microorganisms. These extracts were found to be active against <i>Bacillus cereus, Staphylococcus aureus, Escherichia coli</i> and <i>Candida albicans.</i><br><br>La composición química de los ácidos grasos y la fracción insaponificable de raíces, hojas, y tallos de <i>Daucus crinitus</i> Desf. fueron establecidas utilizando cromatografía de gases (GC) y cromatografía de gases-espectrometría de masas (GC-MS). La fracción de ácidos grasos de los diferentes órganos (hojas, tallos y raíces) se caracterizó por el ácido láurico (17.9, 17.5 y 18.1% respectivamente) y otros ácidos grasos de cadena larga (hasta C22). Diferencias cualitativas y cuantitativas se registraron entre las fracciones insaponificable de los diferentes órganos de <i>D. crinitus</i>. De hecho, las fracciones insaponificable de la raíz, de la hoja y del tallo mostraron cantidades altas de componentes alifáticos (83.4%, 87.2% y 91.4%, respectivamente). Los componentes monoterpénicos, diterpénicos y sesquiterpénicos solo estuvieron presentes en un pequeño porcentaje. Las propiedades antimicrobianas de los extractos de <i>D. critinus</i> fueron ensayadas en cuatro microorganismos diferentes. Estos extractos fueron activos contra <i>Bacillus</i> cereus, <i>Staphylococcus aureus, Escherichia coli</i> y <i>Candida albicans</i>

Volatile oils, lipid constitutes and the antimicrobial activity of Daucus syrticus growing in Libya

“…The GLC of fatty acid methyl esters revealed the presence of saturated fatty acids (35%) and unsaturated fatty acids (65%), among which plasmatic and linolenic acid are the main compounds, respectively. These data were in accordance with those reported by Dib et al [7] collected during April was found to contain a mixture of 33 compounds, accounting for 99.01% of the total who they studied the composition of fatty acids in D. crinitus and found that the major fatty acids are lauric acid and behenic acid.…”

“…The fatty acid fractions of different organs (leaves, stems, and roots) of Daucus crinitus were characterized as lauric acid (17.9, 17.5, and 18.1%, respectively) and other long-chain fatty acids (until C 22 ) [7]. The plants of Daucus spp.…”

Chemical and Biological Study of Essential Oils of Two Populations of Algerian Daucus setifolius Desf.

“…The diameter of inhibition was measured after 24 h at 37°C for bacteria, after 7 days of incubation at 27°C for the fungi and after 48 h of incubation at 37°C for the yeast. The scale of measurement [ 11 ] was the following (disk diameter included): > 20 mm zone of inhibition is strongly inhibitory; < 20 -12 mm zone of inhibition is moderately/midly inhibitory; < 12 mm is not inhibitory. Gentamicin [3 μg/mL(Sigma-Aldrich)], 5-Fluorocytosine, Ketoconazole [5 mg/mL (Sigma-Aldrich)] and DMSO was used as positive and negative controls, respectively.…”

Chemical Composition and Biological Activities of Daucus Aureus Essential Oils From Eastern Algeria

“…It is reported that the genus Daucus was the richest genus of the Apiaceae concerning its essential oil content 5 . The leaves are used in their raw form or in an infusion as depurative and diuretic agents 6 . Some species are used in traditional medicine for the treatment of skin disorders, e.g.…”
