ABSTRACT
Development of a potential antioxidant molecule is gaining importance in the recent years as it plays an important role, in preventing or delaying the onset of certain pathological consequences such as hepatotoxicity, heart diseases and cancer. Cassia tora Linn. (Family :Fabaceae) is an annual herb growing in Asian countries. The plant is reported to have medicinal value as an antimicrobial, antidiuretic, antidiarrheal and antihepatotoxic. In the present study, antioxidant activity of ethanolic extract of Cassia tora leaves was investigated using three in vitro assays, viz., total antioxidant capacity by phosphomolybdenum method, DPPH free radical scavenging assay and ferric ion reducing assay. L-Ascorbic acid was used as a reference antioxidant. The extract showed strong antioxidant activities in all the three assays, indicating that Cassia tora ethanolic extract functions as an efficient antioxidant to scavenge free radicals and reduces free radical induced cellular damage.
