“…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.

“…[5] Essential oil (EO) composition is investigated in only four species from Hyaleoloma (Acrocentron) section of Centaurea genus. [6][7][8] Essential oil may be source of chemical compounds that are good antioxidants and inhibitors of cholinesterases, enzymes important in Alzheimer's disease. [9,10] Essential oils are consisted of a small lipophilic molecules that can easily cross brain-blood barrier and serve as a good therapeutic agents.…”

Centaurea species are used in eastern Mediterranean ethnopharmacology due to variety of bioactive compounds they comprise. Aim of this work was to characterize the Centaurea rupestris L. hydrodistilled essential oil chemical composition and test its biological activity: antimicrobial effect, antioxidant potential and inhibition of cholinesterases. Plant material authentication was by chromosome number counting and genome size assessment with the flow cytometry. Hydrodistilled essential oils were characterized using gas chromatography/mass spectrometry technique GC-MS and GC-FID. The antimicrobial effect was tested using disk diffusion and microdilution methods, antioxidant potential was tested with DPPH and FRAP methods and cholinesterases inhibition was tested with Ellman method. Genome size for C. rupestris species: sample A presented 2C=3.60 (0.10) pg and sample B 2C=3.62 (0.08) pg. The chromosome number was 2n=20 for both samples. The main essential oil constituents in isolated sample A oil, detected with GC-MS and GC-FID were: germacrene D (24.3 %), heptacosane (14.4 %), phytol (6.7 %), β-caryophyllene (5.0 %) and pentacosane (4.5 %). Sample B essential oil had the main constituents: hexadecanoic acid (18.7 %), heptacosane (13.8 %), α-linolenic acid (11.8 %), nonacosane (7.8 %) and germacrene D (5.4 %). Both samples of oil showed broad spectrum antimicrobial effect with good activity against emerging Gram-positive and Gram-negative opportunistic pathogens and pathogenic fungi which indicates the pharmaceutical potential of the C. rupestris essential oil.

“…The chemical composition of essential oils differs in each species or subspecies. The compositional studies of essential oils have been carried out extensively by using gas chromatography-mass spectrometry (GC-MS), which is based on the comparison of the relative retention times/indices and mass spectra of the specific natural compounds found in an essential oil (Adams, 2004;Flamini et al, 2002;Dural et al, 2003;Skaltsa et al, 2003;Simiç et al, 2004;Javidnia et al, 2005;Yaylı et al, 2005;Fokialakis et al, 2002;Jovanovic et al, 2004;Küçük et al, 2006).…”
