“…The genus Centaurea includes a large number of species (more than 500) belonging to the Asteraceae family, which are commonly found in the broader region of the Mediterranean basin and Western Asia [22]. The genus consists of very diverse species with different growth cycle (annual, biennial or perennial plants) and growth habits (edible greens, herbs and bushes), while some of them are traditionally used as edible greens or as medicinal plants due to their bioactive properties [16,[23][24][25][26].…”

Centaurea raphanina subsp. mixta (DC.) Runemark is a wild edible species endemic to Greece. This study evaluated the chemical composition and bioactive properties of wild and cultivated C. raphanina subsp. mixta plants. Wild plants had higher nutritional value than cultivated ones, whereas cultivated plants contained more tocopherols. Glucose and sucrose were higher in cultivated plants and trehalose in wild ones. Oxalic and total organic acids were detected in higher amounts in cultivated samples. The main fatty acids were α-linolenic, linoleic and palmitic acid, while wild plants were richer in polyunsaturated fatty acids. Two pinocembrin derivatives were the main phenolic compounds being detected in higher amounts in wild plants. Regarding the antioxidant activity, wild and cultivated plants were more effective in the oxidative haemolysis (OxHLIA) and thiobarbituric acid reactive substances (TBARS) assays, respectively. Moreover, both extracts showed moderate cytotoxicity in non-tumor cell lines (PLP2), while cultivated plants were more effective against cervical carcinoma (HeLa), breast carcinoma (MCF-7) and non-small lung cancer (NCI-H460) cell lines. Finally, wild plants showed higher antimicrobial activity than cultivated plants against specific pathogens. In conclusion, the cultivation of C. raphanina subsp. mixta showed promising results in terms of tocopherols content and antiproliferative effects, however further research is needed to decrease oxalic acid content.

“…Notably, C. iconiensis contains a more unusual quantity of undec-1-ene (84.3%) [ 28 ]. Moreover, unusual compounds (arachidic acid, α-selinene and octanol) are recognized as active components in several Centaurea EOs [ 29 , 30 ]. Spathulenol is a volatile constituent of C. aphrodisea [ 20 ], C. euxina [ 21 ], C. grisebachii [ 31 ] and C. lycopifolia [ 30 ].…”

The genus Centaurea is recognized in folk medicine for anti-inflammatory, anti-itch, antitussive, purgative, astringent, and tonic activities. To study the chemical determinant for antimicrobial activity essential oils (EOs), five Centaurea species were analyzed including: C. scoparia, C. calcitrapa, C. glomerata, C. lipii and C. alexandrina. Conventional hydro-distillation (HD) and microwave-assisted extraction (MAE), as new green technologies, were compared for the extraction of essential oils. GC/MS analysis identified 120 EOs including mostly terpenoid except from C. lipii and C. alexandrina in which nonterpenoids were the major constituents. Major terpenoids included spathulenol, caryophyllene oxide and alloaromadendrene oxide-2. To probe antibacterial activity, potential EO inhibitors of a bacterial type II DNA topoisomerase, DNA gyrase B were screened via an in silico molecular docking approach. Spathulenol and alloaromadendrene oxide-2 possessed the best binding affinity in the ATP- binding pocket of Gyrase B enzyme. Principal component analysis and agglomerative hierarchical clustering were used for sample classification and revealed that sesquiterpenes contributed the most for accessions classification. In vitro antimicrobial activity against Staphylococcus aureus, Escherichia coli and Aspergillus niger for all EOs were also evaluated. EOs from C. lipii, C. glomerata and C. calcitrapa exhibited significant MIC against S. aureus with an MIC value of 31.25 µg/mL.

“…In terms of volatile compounds, C. balsamita seed seems to be richer than C. albonitens and contains more of these compounds. Ertas, et al [37] identified thirty-two components that constitute 92.8% of the essential oil composition obtained by hydrodistillation from the entire C. balsamita plant. They identified the main components as αselinene (8.5%), hexatriacontane (8.3%), 2.5-ditert octyl-pbenzoquinone (7.4%) and tetracosane (6.0%).…”

Aims: The aim of this study was to determine and compare the potential of Centaurea albonitens and Centaurea balsamita seeds as alternative raw materials for edible oil production and natural antioxidant sources. Study Design: C. balsamita and C. albonitens were harvested from the district of Van province during harvest-maturity period in August-September 2017. The plants were identified by a biologist, Prof. Dr. Murat ÜNAL. The Voucher specimens (B5495, MÜ68611) were deposited at the Virtual Herbarium of Lake Van Basin, Van Yüzüncü Yil University, Faculty of Education. Place and Duration of Study: The study was carried out between June 2017 - January 2019 in Yüzüncü Yıl University, Faculty of Engineering, Food Engineering Department laboratory. Methodology: This study consists of two parts. In the first part, crude oil, moisture, ash, protein content, total phenolic content (TPC), volatile components and antioxidant activities of Centaurea albonitens and Centaurea balsamita seeds were determined. In the second part, fatty acid compositions, tocopherol contents, peroxide values (PV), free fatty acidity (FFA) and color values of seed oils obtained by cold extraction were determined. Results: The antioxidant capacities were determined by the 2,2-diphenylpicrylhydrazyl (DPPH) and the 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. Results were 26.60 and 27.12%, and 80.61 and 95.99 mmol Trolox eq/g for C. balsamita and C. albonitens seeds, respectively. The total phenolic content of the seeds were determined to be 9019 and 11501 mg GAE/kg, respectively. The average α-tocopherol content were found to be 1186 and 1689 mg/kg oil. Oil yields of the seeds were found to be 19.36 and 17.65 %, for C. balsamita and C. albonitens seeds, respectively. In fatty acid profiles; linoleic, oleic, palmitic and stearic acids were determined as the most dominant fatty acids. 22 volatile compounds were detected in C. balsamita seed while this was 26 volatile compounds in C. albonitens seed. Conclusion: In this study, it was concluded that C. albonitens and C. balsamita seeds may be considered as alternative raw materials for edible oil production, and these seeds can be used in the formulation of functional foods due to their high level of α-tocopherol, natural antioxidants and polyunsaturated fatty acids.
