Antioxidant and Antiradical Properties of Rhabdosciadium Anatolyi Flowers and Contents of Vitamin, Trace Element and Mineral

Abstract

The aim of this study was to investigate the antioxidant and antiradical activity of the Rhabdosciadium anatolyi ( R. anatolyi) flowers, an endemic plant grown in the Eastern Anatolia Region of Turkey, by determining the level of vitamins E and C, mineral (Ca, Na, Mg, P, K), and trace elements (Mn, Zn, Cu, Fe, V, Cr, Mo, Co, Sr, Pb, Ti, Tl, Sn, Cd, As). Within the scope of the study, mineral and trace element analyzes were carried out by ICP-OES and AAS, Vitamin E by HPLC, Vitamin C, total phenolic content, total flavonoid, antioxidant capacity, hydrogen peroxide, DPPH, ABTS, superoxide, hydroxyl and hemolysis of erythrocytes with phenylhydrazine, radical scavenging activity of the R. anatolyi flowers methanol extract were determined spectrophotometrically. According to the results, a-tocopherol, ascorbic acid, phenolic content, flavonoid content and total antioxidant activity of the R. anatolyi flowers were 3,99 +/- 0,35 mu mol kg(-1), 346.27 +/- 6.51 mg 100 g(-1), 21.94 +/- 0.37 mg gallic acid g(-1), 5.60 +/- 0.13 mg quercetin g(-1) ve 29.65 +/- 0.26 mM ascorbic acid g(-1), respectively. Consequently, the mineral, trace element, vitamin E and vitamin C, total phenol and flavonoid levels in the R. anatolyi flowers were high, and the R. anatolyi flowers methanol extract effectively inhibited free radicals. From this point of view, it is thought that it can be used in the preventive treatment of many diseases that may be caused by free radical species and that these data will be a reference for other studies.
