Evaluation of Antioxidant Properties, Trace Element and Mineral Composition of Dactylorhiza umbrosa (Kar. & Kir.) Nevski (Orchidaceae)

In this study, antioxidant properties, trace element and mineral composition of Dactylorhiza umbrosa (Kar. & Kir.) Nevski (Orchidaceae) grown in the East Anatolia Region of Turkey was determined. The concentrations of trace element and mineral were determined by using inductive paired plasma-optical emission spectrometer (ICP-OES). It has founded that the quantities of important trace elements Mn, Cu, Co and Se were high and also the quantity of the Mg mineral was quite high. Dactylorhiza umbrosa (Kar. & Kir.) Nevski plant's element quantities were determined to be Sr > Mg > V > Mn > Li > Ti > Cu > Se > Cr > Pb > Co > As > Be > Zn > Cd respectively. Total antioxidant activity, total phenolic and flavonoid contents were 12.44 ± 0.20 mM ascorbic acid g-1, 4.97 ± 0.48 mg gallic acid g-1 and 4.51 ± 0.29 mg quarcetin g-1 respectively in methanol extracts of Dactylorhiza umbrosa (Kar. & Kir.) Nevski plant. The presence of high levels of some trace elements, antioxidant activity, total phenolic and flavonoid contents in the methanol extract may have important to the showed antioxidant properties.
