Determination of Multi-Elemental Analysis and Antioxidant Activities of Helichrysum arenarium (L.) Moench Species

Abstract

In this study, multi-elemental analysis and antioxidant activity of samples belonging to two different populations of Helichrysum arenarium (L.) Moench known as the immortal flower was determined. The results obtained were compared among themselves. Ca, Mg, Al, Fe, Na, Li, Be, B, Ti, Cr, Ni, Zn, Mo, and Pb element contents of the sample belonging to the B population were determined that be higher than that of the other population. The K, V, Mn, Co, Cu, As, Se, Sn, and Ba element contents of the sample belonging to the G population were determined that be higher than that of the other population. When the antioxidant activity results of the species were evaluated; according to the CUPRAC (Cupric Reducing Antioxidant Capacity) method, the sample extracts of the B and G populations were determined that showed lower activity than the standard BHA, BHT, and Trolox values at 20 and 40 µg/mL concentrations, and showed close activity compared to the standards at 80 µg/mL concentrations. The species was determined that be antioxidant activity even at low concentrations. According to DPPH (2,2-diphenyl-1-picrylhydrazyl) method, the antioxidant activity of the extract of the B and G populations was determined as 22.95 and 23.76 mg TE/mL, respectively.
