Marine algae act as the vital source of marine ecosystem. To assess the antioxidant properties of marine algae Valoniopsis pachynema
and Sargassum swartzii.
Direct extraction method was used to prepare the algal extracts. Antioxidant activities has been evaluated using 2,2-diphenyl-1-picrylhydrazyl DPPH Radical Scavenging Assay, Hydrogen peroxide (H2
) scavenging assay, Total phenolic content, β-carotene bleaching assay, Nitric oxide radical scavenging assay. High antioxidant activity was exhibited using Sargassum swartzii
In Total phenolic content marine algae Valoniopsis pachynema
showed high antioxidant activity. Comparative analysis results showed that both the algae could be used as antioxidant agents. The marine algae Valoniopsis pachynema
and Sargassum swartzii
methanol extracts exhibited effective antioxidant activities. Hence they could be used as antioxidants.Pages: 426-430 | 1188 Views 44 DownloadsDownload Full Article:
