For a long time, many cultures around the world have used Tribulus terrestris L. in the prevention and treatment of various diseases. In this study, the antioxidant activity and total phenolic and flavonoid content of extracts obtained with various solvents from T. terrestris plant collected from different localities in Kahramanmaraş were investigated. In addition, the fixed oil content of the extracts was examined by GC-MS analysis and as a result, 26 different fatty acids were determined. The main fatty acid components of plant extracts are linoleic acid, oleic acid and palmitic acid. The total phenolic substance value of plant extracts varies between 2.20-18-77 mg g-1, total flavonoid amount varies between 0.06-0.50 mg g-1, FRAP value varies between 6.16-23.50 µg g-1 and DPPH value varies between 1.54-10.54 µg mL-1. It was observed that the solvents used in extraction affected the bioactivity values rather than the locations. Although the absorbance values of the extracts obtained with hexane were high, low extract yield affected the results. The highest values in all characters examined were obtained from ethanolic extracts.
