The ethanolic extract of Tragopogon longirostis var. longirostis, a wild edible plant in Anatolia was isolated, and its antioxidant, mutagenic, and antimutagenic properties were investigated.
Materials and Methods:

The antioxidant activity (AA) was determined by the inhibition of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, total AA, and phenolic compounds. The mutagenic and antimutagenic activities were investigated by Ames Salmonella/microsome mutagenicity test.
Results:

The IC50 value for DPPH radicals was 7.84 ± 0.603 mg/mL. The total AA increased with an increase in the concentration of the extracts (1, 5, 10, 20, and 30 mg/mL), containing linoleic acid emulsion. The total phenolic content was 284.71 ± 5.6 mg gallic acid equivalent/g extract. The results showed that the ethanolic extract can be considered safe, because it does not have any mutagenic effect at the tested concentrations. As a result, the ethanolic extract of the leaves exhibited antimutagenic effects at 2.5, 0.25, and 0.025 mg/plate concentrations.
