ABSTRACT: Antioxidant activity of Lycoperiscon esculentum fruit varieties in two different solvent fractions has been checked by different in vitro models. The methanolic fraction of S-22 variety showed significant antioxidant activity as well as it contained relatively higher amount of total phenolic and flavonoid compounds over Samrudhi variety. S-22 variety showed IC50 values as 115.92 μg/ml and 142.90 μg/ml to scavange DPPH; OH- and O2.- generation respectively. 1 gm of S-22 extract in methanolic fraction contained 35.27 mg phenolic compound equivalent to gallic acid and 36.83 mg flavonoid equivalent to quercetin respectively. Methanolic fraction in all the cases showed promising activity over aqueous fraction and may be due to the fact that antioxidant compounds were extracted more in methanol.
