Abstract
This study was carried out on turnip (avtitu) obtained from a radish ecotype grown in Eruh region of Siirt. Antioxidant capacities, total phenolic and flavonoid amounts of DPPH (free radical scavenging), Ferric ion reducing antioxidant power (FRAP) analyses were performed in extracts obtained from radish with different solvents. In addition, the metal content of the samples and the elemental analysis of the soil samples taken in the area where they were collected were made.
 In this study, the content of total phenolic, total flavonoid, DPPH highest % inhibition values and the highest values of the ferric ion reducing antioxidant power (FRAP) were 71.97 ± 14.54 mg / mL Gallic acid equivalents, 298.17 ± 12.81 mg / mL routine equivalent, 66.88% and 3.29 ± 0.01 mg / mL FeSO4 equivalents were detected in the above-ground fractions methanol extract, respectively. 
 Samples of the turnip beverage traditionally produced by the people from the Eruh region of Siirt were randomly obtained from eleven families. Some physicochemical tests such as pH, water activity, Oxidation-Reduction (O / R; Eh) Potential Value, colour analysis, dry matter content and % salt ratio and microbiological tests such as TMAB, yeast, mould, Staphylococcus species, Lactobacillus spp., coliform group bacteria and E. coli were applied to these avtitu samples.
