Abstract

This study's objective was to extract and evaluate the antioxidant activity of phenolic acids from biomass Spirulina sp.LEB-18. The analysis of phenolic compounds was made according to the Folin-Ciocalteu method, using gallic acid as the standard. The antioxidant activities were measured using different techniques such as the kidnapping of DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS• + radical capture (2.2'-azinobis (3-sulfonic acid ethylbenzothiazoline-6), the ?-carotene system / linoleic acid, and the antioxidant power of reduction of iron (FRAP), its antioxidant activities determined through the different methodologies, showed more significant inhibition compared to ABTS radical.
