The basic quality parameters, total polyphenol, o-diphenol content, oxidation stability (Rancimate) and antiradical activity [1,1-diphenyl-2-picrylhydrazyl (DPPH)] were determined in the oil samples. The highest induction period (IP) is 36.42 hours found in the Halhali variety (from Gaziantep province), which has strong radical scavenging activity (RSA) (methanol: 96.72% in water essence and 94.91% in total oil) in all samples. . for the total phenol and oBu variety -diphenol content was 495.42 and 76.89 mg of caffeic acid/kg of fat, respectively. Oxidation stability and antiradical activity of Kilis oilcloth variety (from Kilis province), compared with other varieties (IP; 10.40 h, RSA
