  ABSTRACT: Induced accumulation of polyphenolics and flavonoids in cyanobacterial strains grown under different salt concentrations is correlated with their growth under stress conditions and enhanced antioxidant activity. Plectonema boryanum, Hapalosiphon intricatus, Anabaena doliolum and Oscillatoria acuta grown for 21 days under different salt concentrations (80, 160, 240, 320 and 400 mM) in BG11 medium showed differential growth responses in terms of biomass, total protein, chlorophyll content, total content of polyphenol, flavonoid and carotenoid, accumulation of phenolic acids (gallic, caffeic, chlorogenic, ferullic and vanillic) and flavonoids (rutin and quercetin). Cyanobacterial extracts showed prominent free radical scavenging antioxidant activity (AOA) in terms of % DPPH discoloration. Highly significant (p
