The present study aimed to determine the contents of five flavonols and two glycoalkaloids as well as the antioxidantactivities of leaf ethanol extracts of 50 tomato accessions. The antioxidant activity was assessed using different tests: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), 2,2-diphenyl-1-picryl hydrazyl (DPPH), nitric oxide (NO), and total polyphenolcontent (TPC). Flavonols and glycoalkaloids contents were determined using a high performance liquid chromatography-diode arraydetector system. Among five flavonols and two glycoalkaloids, naringenin and tomatine were detected in tomato leaves at highconcentrations. Of the 50 tomato accessions, IT 229711, IT2365203, and IT 207224 were found to have the highest contents ofquercetin, kaempferol, and tomatine, respectively. Leaf extract of IT189949 exhibited the highest relative antioxidant capacity index(RACI). Among the five flavonols, myricetin showed positive correlations with DPPH, ABTS, and NO, while isorhamnetin hadpositive correlation with DPPH. These results will expand the chemical constitution database and provide information on tomatoleaves. They are valuable for the development of functional foods or feed-additives.
