Study of antioxidant activity, oxidative DNA damage and protein oxidation inhibition effect of Tunceli garlic (Allium tuncelianum)

In this study, antioxidant activity and oxidative DNA damage and protein oxidation inhibition effect of the ethanol extract of cultivated garlic Allium tuncelianum were investigated that is grown Ovacık district of Tunceli province. In this study the total amount of phenolic and flavanoid components of the ethanol extract of Allium tuncelianum was investigated. Gallic acid was used as the standard phenolic and quercetin was used as the standard flavonoid. It was found that the total phenolic component content of the ethanol extract at 0.5 mg / ml was equivalent to 16.70 ± 1.21 μg gallic acid and the total flavonoid component content was equivalent to 6.73± 0.11 μg quercetin. A. tuncelianum ethanol extract was found to have the activity of inhibiting lipid peroxidation in the FeCl2-H2O2 system. While the extinguishing activity of the DPPH radical of the ethanol extract of garlic was found to be % 89.7 ± 0.3 at 2000 μg/ml concentration, The oxidative damage induced by Allium tuncelianum ethanol extract in the H2O2 / Fe3+ / ascorbic acid system and Bovine Serum Albumin (BSA) protein was found to be between % 61.88 ± 2.50 - 76.23 ± 3.14 in the concentration range of 50-1000 μg / ml. It was seen as a result of thesis studies that the ethanol extract of Allium tuncelianum garlic is a good antioxidant and the activity of protein oxidation and DNA damage inhibition are very good.
