ABSTRACT
n vitro antioxidant activity of petroleum ether, benzene, ethyl acetate, methanol and ethanol extracts of mangrove herb Salicornia brachiata Roxb. leaf have been tested using various antioxidant model system viz, DPPH, hydroxyl, superoxide, ABTS and reducing power. Methanol extract of S. brachiata is found to possess higher DPPH radical scavenging activity while methanol and ethyl acetate extracts are found to possess higher hydroxyl radical scavenging activity. Ethanol and methanol extracts of S. brachiata exhibited highest superoxide and ABTS radical cation scavenging activity. Methanol extract of leaf of S. brachiata showed the highest reducing ability. This study indicates significant free radical scavenging potential of S. brachiata leaf which can be exploited for the treatment of various free radical mediated ailments.
Keywords: Mangrove, Salicornia brachiata, Antioxidant activity, Methanol, ABTS.
