“…This differentiation could suggest a chemotype variation in C. aladaghensis, since these different main components have different biosynthetic origins. Similar situation was also reported for C. ensiformis in two different articles that indicate different essential oil compositions 29,39 . One of the reports indicate main essential oil components as carvacrol (17.4 %), phytol (6.0 %), hexadecanoic acid (13.2 %) 29 and the other one reports as β-eudesmol (29.8 %), caryophyllene oxide (7.6 %) and hexadecanoic acid (8.0 %) 39 .…”

“…Previous reports on the essential oil composition of Centaurea species indicate main components as caryophyllene 14,15 , spathulenol 16,17 , eudesmol [17][18][19] , germacrene 16,20-24 as sesquiterpenes; hexadecanoic acid 5,18,[25][26][27][28][29][30][31][32][33][34][35] , tetradecanoic acid 29 , dodecanoic acid 26,29,33 as fatty acids; heptacosane 5,17,22,25,31,35,36 , tricosane 22,31,35 , pentacosane 22 , nonacosane 5 as higher alkanes and pinenes 16 , terpinenes 16 , carvacrol 29 as monoterpenes. Until now 42 taxa of Centaurea were investigated for essential oil composition from Turkey; main components of these oils were given in Table 1.…”

Essential oil composition of Centaurea stenolepis Kerner flowers and stems were investigated with GC, GC-MS. Flowers and stems of C. stenolepis had very low essential oil yield <0.01 % (v/w). Twenty eight compounds were identified in the flower oil which represent 53.5 % of the oil. Main components of the flower oil include caryophyllene oxide 12.6 %, hexadecanoic acid 10.6 % and β-Eudesmol 7.2 %. Forty compounds were identified in the stem oils which represent 74.2 % of the oil. Main components of the stem oils include hexadecanoic acid 38.4 % and phytol 12.9 %. Both flower and stem oils were rich on oxygenated sesquiterpene hydrocarbons and fatty acids.

“…Hexadecanoic acid was reported as major compound in the essential oils of Centaurea urvillei subsp. urvillei, C. calolepis, C. euxina, C. sibthorpii and C. amanicola [42][43][44][45] . According to these results, the essential oils of C. urvillei species were characterized with high contents of hexadecanoic acid.…”

This study was focused on the analysis of the phenolic content, fatty acid composition, volatile compounds and antioxidant activity of methanol extract from Centaurea urvillei subsp. stepposa. The antioxidant capacity were detected as 43.35 mg TEs/g, 52.18 mg TEs/g and 98.78 mg TEs/g for DPPH, FRAP and CUPRAC, respectively. Chlorogenic acid and apigenin were the major phenolic components in the extract. Linoleic acid (49.54 %) was the predominant fatty acid in the oil. 1, 3-cyclooctadiene (25.08 %) was major components in the essential oil. The study concluded that Centaurea urvillei subsp. stepposa can be used as a source of natural antioxidants for food and pharmacological industry.

“…Several Centaurea species have been used in folk medicine for various ailments such as antidiarrheic, antipyretic, diuretic, choleretic, antiinflammatory and antibacterial (Arif et al, 2004;Kargıoglu et al, 2008;Kargıoglu et al,2010). Many Centaurea species, such as C. hadimensis (Flamini et al, 2002), C. cyanus and C. depressa (Karamenderes et al, 2008) were studied upon the determination of essential oil components. Also, the antioxidant properties of the Centaurea species such as C. mucronifera (Tepe et al, 2006), C. ensiformis (Ugur et al, 2009), C. calolepis (Karamenderes et al, 2007) and C. solstitialis (Tekeli et al, 2008) were reported using various methods.…”

RESUMEN Capacidad antioxidante y perfil de ácidos grasos deLa capacidad antioxidante de extractos metanólicos y composición de ácidos grasos de C. kotschyi var. pérsica fueron investigados. Seis métodos químicos diferentes fueron realizados para la determinación de la capacidad antioxidante. La composición de ácidos grasos fue analizada por cromatografía de gases. Los valores de IC 50 de los extractos fueron 37.09 µg/ml (en el ensayo con DPPH). En el sistema β-carotene/ácido linoleico, el extracto mostró un 65.22% de inhibición frente a la oxidación del ácido linoleico. La cantidad total de contenido fenólico y capacidad antioxidante total fueron 36.52 mg equivalentes de ácido gallico (GAE)/g y 74.93 mg equivalentes de ácido ascórbico (AE)/g, respectivamente. El principal ácidos graso encontrado, por análisis de CG, en C. kotschyi var. pérsica fue el C 18:3 ω3 (ácido α-linolenico). Los resultados presentados aquí indican que C. kotschyi var. pérsica posee unas fuertes propiedades antioxidantes. Además, las especies pueden ser usadas como aditivos naturales en los alimentos, en cosmética y en industria farmacéutica. The antioxidant capacity of the methanolic extract and the fatty acid composition of C. kotschyi var. persica were investigated. Six different chemical methods were used to determine the antioxidant capacity. The fatty acid composition was analyzed using gas chromatography. The IC 50 value of the extract was determined as 37.09 µg/ml (in the DPPH assay). In the β-carotene/linoleic acid system, the extract exhibited 65.22% inhibition against linoleic acid oxidation. The amount of total phenolic content and total antioxidant capacity were detected as 36.52 mg gallic acid equivalent (GAE)/g and 74.93 mg ascorbic acid equivalent (AE)/g, respectively. The major fatty acid in the composition of C. kotschyi var. persica was found to be C 18:3 ω3 (α-linolenic acid) by GC analysis. properties. Therefore, the species can be used as a natural additive in food, cosmetic and pharmaceutical industries.
