“…Several species from the genus Centaurea are interesting from medicinal and pharmacological perspective, and thus recently the subject of intensive research [3][4][5][6][7][8][9][10][11][12][13][14]. Since structural and phytochemical characteristics of C. sadleriana were previously unknown, our work highlights this information.…”

“…As Centaurea species were generally classified as essential oil-poor plants, the investigations of these and antioxidant properties are rather scarse. However, antiinflammatory, antimicrobial, antifungal and cytotoxic activities had been found for extracts or natural products of some of the Centaurea species [3,[5][6][7][8][9][10][11][12][13][14].…”

The lamina, main vein and peduncle anatomical properties of Centaurea sadleriana Janka plants from two populations, were examined using light and scanning electron microscopy. The indumentum was comprised of glandular and non-glandular trichomes of two types. The leaves were amphistomatic, isolateral, with strongly developed palisade tissue. Secretory ducts were observed along the phloem or sclerenchyma of large vascular bundles. Collenchyma alternated with chlorenchyma in the main vein and peduncle. Large groups of strongly lignified sclerenchyma were present along the phloem of peduncle vascular bundles. These features, together with thickened walls of epidermal cells and cuticle, numerous trichomes and thick-walled parenchyma in the perimedullar zone, were perceived as a xeromorphic peduncle structural adaptation. Non-enzymatic antioxidant compounds of phenolic origin were detected in small amounts and their respective content was higher in leaves compared to inflorescences. Compounds of phenolic orgin showed positive correlation with total potenial of antioxidant activity indicated by the DPPH assay. Greater total quantity of polyphenols and tannins was detected in leaves of plants from Zobnatica locality, while leaves of plants from Rimski Sanac were characterized by higher content of total flavonoids and proantocyanidins. Phytochemical analysis showed that dominant secondary biomolecules in inflorescences were phenolic pigments including anthocyanins and leucoanthocyanins, and free quinones in leaves.

“…Many species of genus Centaurea L. (Asteraceae) have traditionally been used for the treatment of various ailments 3,4 . The genus Centaurea has been the subject of many antimicrobial and antioxidant activity properties [5][6][7][8][9][10][11][12][13][14][15][16][17] . The plants possess potent bioactive compounds capable of preventing and treating most oxidative related diseases.…”

The antimicrobial activity of the ethanol, acetone, ethyl acetate and chloroform extracts from Centaurea persica Boiss., C. polyclada DC. and C. consanguinea DC. (Asteraceae) were investigated by agar-well diffusion assay. All of the extracts exhibited an antimicrobial effect against most of the bacteria and all of the yeasts tested. The plant extracts were also screened for radical scavenging potential using a 1,1-diphenyl-2-picryl-hydrazyl (DPPH) in vitro model system for antioxidant activity. Ethyl acetate extracts showed the most significant inhibitory activity. Therefore, the minimal inhibitory concentration (MIC) of only ethyl acetate extracts of the samples was determined and C. consanguinea showed the highest antimicrobial effect. However, the ethanol extract of C. polyclada at 0.5 mg/mL concentration displayed the highest antioxidant activity. This activity was followed by ethanol extracts of. C. persica, ethyl acetate extracts of C. polclada, C. persica and C. consanguinea respectively.
