Abstract
The present study focused on determining the antioxidant properties of the Enteromorpha compressa (Linnaeus) Nees, Enteromorpha flexuosa (Wulfen) J. Agardh, Enteromorpha intestinalis (Linnaeus) Nees, and Enteromorpha prolifera (Müller) J. Agardh, ethanol crude extracts, from the green algae. The evaluation of antioxidant properties was estimated and determined by using ten standard methods namely 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2’-azino-bis 3-ethylbenzthiazoline-6-sulphonic acid (ABTS), metal chelating activity, hydrogen peroxide radical assay, superoxide radical scavenging (SOD), reducing power, hydroxyl radical assay, nitric oxide (NO) scavenging assay, ferric reducing antioxidant power (FRAP) assay and total antioxidant activity assay. The tested green algae also had antioxidant activity like algae diatom which are showing good antioxidant potential. These algae had a lesser radical scavenging ability than standard ascorbic acid. This study suggests that ethanol crude extracts contain different potential antioxidant compounds capable to scavenge different types of free radicals.
