As part of biochemical studies on the genus Centaurea, eight known flavonoids were isolated and identified from Centaurea furfuracea, namely apigenin 1, hispidulin 2, cirsimaritin 3, 5,7,4'-trihydroxy-3-methoxyflavone 4, apigenin-7-O-glucoside 5, apigenin-7-O-methylglucuronide 6, hispidulin-7-O-glucoside 7 and patelutin-7-O-glucoside 8. Dried aerial parts of C. furfuracea were extracted with 70% MeOH, partitioned with n-BuOH, and the residue was separated via polyamide column chromatography, preparative paper chromatography (Whatman 3 MM paper using 15% aqueous HOAc and BAW as solvents), and purified by Sephadex LH-20. Structures were confirmed by UV, MS, 1H NMR spectroscopy and co-chromatography with authentic samples. Chemotaxonomic analysis indicated Centaurea furfuracea is an Algerian endemic species; hispidulin-7-O-glucoside (one of the four aglycones and four glycosides isolated) is common in Algerian Centaurea species (previously found in C. incana and C. niceansis), and this species contains no C-glucosylflavonoids.
