“…[14] Good antimicrobial activity was previously found in some Centaurea species EO. [10,[15][16][17][18][19][20][21][22] Due to a need for an authentic plant material, evaluated both with a botanist expertise and molecular methods, the genome size and chromosome number were assessed. In botanical authentication of plant material, together with morphological traits, a genome size, the amount of DNA in the un-replicated haploid nucleus of an organism, are important biological traits used for plant characterization.…”

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 antibacterial and antifungal activities of Centaurea species have been attributed to their sesquiterpene lactone content or to the volatile compounds of the plants, as demonstrated by a series of experiments (Vajs et al, 1999;Barrero et al, 2000;Skaltsa et al, 2000;Saroglou et al, 2005;Skliar et al, 2005;Bulent Kose et al, 2007).…”
