Abstract: In the present study, the strain Synechococcus sp. was isolated from the Cochin backwaters and its antioxidant activity was determined by in vitro antioxidant assays. Methanol fraction exhibited the highest phenolic content 44.33±0.433 µg GAE. Antioxidant capacity was found to be 83.63±0.50 µg AE. Ferric reducing antioxidant power and 2, 2 diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity was found to be concentration dependent. The de-oxy ribose free radical was scavenged at 22%. Methanol and dimethyl sulphoxide fractions were found to be effective for the extraction of antioxidant principle present in the strain.
