Antioxidant activities of phenolic compounds of Centaurea ensiformis P.H. Davis [Centaurea ensiformis P.H. Davis'in fenolik bileşiklerinin antioksidan aktiviteleri]

The aim of the present study was to investigate the antioxidant activities of 11 phenolic compounds previously isolated from an endemic Centaurea ensiformis P.H. Davis (Asteraceae) by 2,2-diphenyl-l-picryl-hydrazyl (DPPH) and ABTS decolorization assays. These compounds consisting of 2 phenolic glycosides (tacioside and protocatechuic acid), 2 acetophenon glycosides (picein and 4-hydroxyacetophenon 4-O-[6'-O-ß-D-apiofuranosyl]-ß-D-glucopyranoside), 1 coumarin glucoside (scopolin), 4 flavonoid glycosides (vicenin-2, schaftoside, neoschaftoside and chrysoeriol-7-O-mtinoside), 1 phenylpropanoid glycoside (sy-ringin) and 1 neolignan glucoside (dihydrodehydrodiconiferyl alcohol 4-O-ß-D-glucopyranoside). Protocatechuic acid and tachioside had the highest activity (DPPH IC50: 6.47 and 22.87 mM; TEAC: 33.2±0.18 and 31.2±0.99, respectively) in both methods. Dihydrodehydrodiconiferyl alcohol 4-O-ß-D-glucopyranoside also showed high activity compared to ascorbic acid in DPPH assay (IC50: 27.7 mM). Our results concluded that the C. ensiformis have a potential source of antioxidants of natural origin
