Description 974-977
Antioxidant activity of methanolic extracts of three Cyanobacteria, Oscillatoria limosa C.Agardh ex Gomont, Synechococcus elongates (Nägeli) Nägeli and Synechocystis aquatilis var. minor Geitler isolated from Cochin estuary was studied. Phycobiliproteins were analysed, phycocyanin and allophycocyanin were the major pigments in O. limosa and S. aquatilis while phycoerythrin was the major one in S. elongatus. Total phenolic content, total antioxidant activity and nitric oxide scavenging activity was maximum in O. limosa (33.4µg GAE±0.45, 97µg AE±0.327 and 55.16%±0.51. Superoxide radical scavenging activity was shown maximally by S. elongatus (97%±0.871) followed by O. limosa (91.5%±0.781) and lowest in S. aquatilis (90.66%±0.611). S. aquatilis maximally inhibited lipid peroxidation (94.47%±0.472).
