Abstract :In this study, the amounts of vitamins, beta-carotene, lycopene, glutathione insert ignore into journalissuearticles values(GSH, GSSG);, malondialdehyde insert ignore into journalissuearticles values(MDA);, and hydroxyneoneal insert ignore into journalissuearticles values(4-HNE); in eggplant samples grown in Turkey insert ignore into journalissuearticles values(dark and light colored eggplant); and Nigeria insert ignore into journalissuearticles values(white garden egg, bitter apple and bitter tomato); were determined by HPLC. In addition, the total amount of phenolic, and flavonoid substances and antioxidant capacity insert ignore into journalissuearticles values(ABTS, IC50); were determined by a UV-Visible spectrophotometer. The amounts of vitamins A, E, β-carotene and lycopene were found to be in the ranged of 0.13 -3.63; 3.63-39.0; 1.87-30.5; 1.52-6.79 µg/g dw, respectively. The amounts of vitamin C, B1, B2, B3, B5, B6, B9 and B12 ranged 357-1136; 11.0-95.6; 1.9-5.4; 83-265; 30.16-65.43; 127-348; 24.74-78.6; 0.11-0.68 µg/g dw, respectively. GHS, GSSG, MDA and 4-HNE were found to be in between 364-1930; 225-962; 1.5-8.4; 24.57-38.25 µg/g dw, respectively. While the total phenolic substance was between 706-1260 µg GAE/g dw, the total amount of flavonoid substance was found to be in between 167-356 µg QE/g dw. ABTS values ranged between 365-692 µmol Troloxs/g dw, while IC50 values were in 65.1-99.3 µg/mL. It can be said that the differences observed in the parameters observed in eggplant varieties grown both in Turkey and Nigeria are due to genetic and geographical differences.
