Abstract

This study was conducted to investigate the in-vitro antioxidant activity of methanolic extract of green alga Valoniopsis pachynema. The free radical scavenging activity of the extracts was measured by superoxide; hydroxyl and nitric oxide radicals and the antioxidant potential were compared with commercial antioxidants, such as Butylated Hydroxy Toluene (BHT) and L- ascorbic acid. The antioxidant activity of experimental algae showed a dose dependent increase when compared to commercial antioxidants. The significant free radical scavenging activity of Valoniopsis pachynema might be attributed to algal contents of carotenoids, free phenols and fatty acids.
