Allium scorodoprasum L. subsp. rotundum (L.) STEARN is a medical and aromatic plant whichgrows naturally in various countries of the world. The purpose of this study was to determine thenatural antioxidant content and antioxidant activity of Allium scorodoprasum L. subsp. rotundum(L.) STEARN plant, an Allium subspecies of the Alliaceae family. Plants which grow naturally in 7different locations of 3 cities (Samsun, Nevşehir and Tokat) of Turkey were used in the study. Thepurpose of this study was to determine the natural antioxidant content and antioxidant capacity ofwild leek plant, an Allium subspecies of the Alliaceae family, which grows in three different cities(Samsun, Nevşehir and Tokat). The material of the study consists of 42 wild leek samples from 7different locations of Samsun, Tokat and Nevşehir. Some physicochemical characteristics andantioxidant features of both bulbs and leaves of samples were determined separately; allicin, anorganosulfur compound, was specified qualitatively and thermal behaviours of the samples weremonitored through TGA/DSC analysis. As a result of the analyses conducted, in the bulb and leafparts of the samples, total phenolic matter values were 254.51-927.81 and 1929.05-19645.24 mg/kg,FRAP was 0.80-5.20 and 14.31-47.83 mM TE/g, DPPH free radical scavenger effect was 0.99-9.02and 36.61-241.06 µmol TE/g and ascorbic acid content was 29.14-314.01 mg/kg and 200.64-1383.16 mg/kg, respectively. These data reveal that the leaf’s of A. scorodoprasum subsp. rotundumplants are rich in antioxidants. In conclusion, it was found that the antioxidant activity of the plantsdiffers significantly in terms of the parts of the plant and growth location.
