Determination of the metal content and biological activities of the radish plant consumed as a turnip by the public in Siirt region

In this thesis study (Eruh) was made on avtütı (turnip) obtained from a radish ecotype grown in Siirt region. The antioxidant capacities, total phenolic and flavonoid amounts of DPPH (free radical scavenging), Ferric ion reducing antioxidant power (FRAP) analyzes were performed in extracts obtained from radish with different solvents. As a result of the study, the highest value of total phenolic substance was found in the methanol extract of the above ground parts with 71.97 ± 14.54 mg / mL Gallic acid. Total flavonoids were found in the methanol extract of the above ground parts with the highest value 298.17 ± 128.13 mg/mL rutin equivalent. DPPH was detected in methanol extract in the upper thoracic part of radish samples with the highest % inhibition value of 66.88%. Ferric ion reducing antioxidant power (FRAP) was found to be the highest value of 3.29 ± 0.01 mg/mL FeSO4 equivalent in the above ground methanol extract. In terms of soil analysis, it has been determined that the organic matter ratio is good, the absorbable phosphorus is high and the available potassium is good.
