Algae have been consumed as food and medicine for centuries. Their benefits are so pronounced, due to high concentrations of vitamins, minerals, antioxidants and proteins, that they are commonly referred to as superfoods. R-phycoerythrin (R-PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in large quantities in red algae. It contains covalently bound open chain tetrapyrolle pigments: red phycoerythrobilin and yellow-orange phycourobilin. This study aims to evaluate the antioxidant potential of R-PE from commercially available red alga Porphyra spp. ("nori"). Two other phycobiliproteins (with dark blue phycocyanobilin pigment): R-phycocyanin (also isolated from Porphyra spp.) and C-phycocyanin (from Hawaiian Spirulina Pacifica), were used for comparison purposes. Purified phycobiliproteins were evaluated for antioxidant and metal ion chelating activity by various in vitro antioxidant assay systems: DPPH–, ABTS–, hydroxyl radical–, and super...oxide anion radical–scavenging activity, ferric ion reducing ability of plasma (FRAP) assay, ferrous ion-chelating activity (FICA), and reducing power (RP) assay. The results showed R-PE exhibit concentration-dependent antioxidant potential similar to, if not better than that found in phycocyanins, confirming the exceptional value of R-PE as a nutraceutical (dietary supplement, functional food and pharmaceutical).
