Screening of microalgae for antioxidant activities, carotenoids and phenolic contents

Ten different microalgal species were screened for their antioxidant activity using 2,2´- diphenyl-1-picrylhydrazyl (DPPH) scavenging assay, both total phenolic and carotenoid contents were determined. The ethanolic extract of Oscillatoria sp. showed the highest antioxidant activity (69.1), while t...
