Analysis and Comparision of Antioxidant Activity of Gracilaria Edulis and Gelidium Acerosa

The present study investigates about the antioxidant activity of red algae Gracilaria edulis and Gelidium acerosa by radical scavenging method, DPPH assay. The ethyl acetate and ethanolic extracts of the two red algae was prepared keeping BHT as a standard.Gelidium acerosa showed the highest antioxidant activity compared to Gracilaria edulis. The absorbance was recorded at 517 nm.
