Total phenolic concentration of the extracts was estimated with Folin-Ciocalteu reagent using gallic acid as standard. Free-radical scavenging activities were determined based on 1,1-diphenyl-2-picrylhydrazyl radical (DPPH). The copper(II) ion reducing ability of polyphenols is measured by CUPRAC method. Results were compared with standard butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA).eninfo:eu-repo/semantics/closedAccessAntioxidantFree radicalEnteromorpha intestinalisDPPHFolin-CiocalteuCuprac methodArticle21865256528Q4WOS:000269018300105Q4
