Ethanolic fractions of Lycoperiscon esculentum fruit varieties namely S-22 and Samrudhi were evaluated for free radical scavenging property in four different assay model. Among the two local tomato varieties tested, S-22 fruit variety found superior over Samrudhi fruit variety possessing higher ability to scavenge DPPH. , NO. , OH. , O 2 .-in reaction mixture. The free radical scavenging property of both types of fruits is due to their polyphenolic content. It was observed that different
more » ... at different radical scavenging action of fruit extracts was directly related to their respective phenolic and flavonoid components. Total phenolic and flavonoid content in S-22 extract was found 29.13 and 33.03mg/g respectively. The S-22 extract also possessed more activity in ferric to ferrous transformation. Thus, tomato fruit could be considered as a cheap, easily available natural source of antioxidant.
