Analysis of Iron and Polyphenols in Brown and Red Macroalgae from Antarctica

Antarctica, the White Continent, is the refuge of typical species, where temperatures range from -85 to2 oC, UV radiation can penetrate 30 m depth and salinity reaches 32-34%. Among these species, brownmacroalgae (Pheophytas) and red macroalgae (Rhodophytas) are mainly evaluated as potential food an...

Description
Summary:Antarctica, the White Continent, is the refuge of typical species, where temperatures range from -85 to2 oC, UV radiation can penetrate 30 m depth and salinity reaches 32-34%. Among these species, brownmacroalgae (Pheophytas) and red macroalgae (Rhodophytas) are mainly evaluated as potential food andhealth resources for mankind. The macroalgae collected in February 2019 were taxonomically classifiedinto 6 species: Desmarestia confervoides, (hacer la consulta con el autor/IMARPE) Desmarestia antarctica,Himantothallus grandifolius, Palmaria decipiens, Gigartina skottsbergii and Curdiea racovitzae. Thisresearch determined organic matter ranging from 12 to 20%, iron (atomic absorption), polyphenols andflavonoids (quantitative methods). The results revealed that the content of iron ranged from 6.72 to 154 mg%,polyphenols from 22.4 to 78.4 mg% and flavonoids from 10.09 to 21.31 mg%. We conclude that this researchallowed us to know the iron and antioxidant characteristics of 6 most common Antarctic species. La Antártida, Continente Blanco, es el refugio de especies típicas donde las temperaturas oscilan entre-85 a 2 oC, con radiación UV capaz de penetrar 30 m de profundidad y salinidad de 32-34%. Dentro deellas, las macroalgas pardas (Pheophytas) y rojas (Rhodophytas) son importantes para evaluarlas comopotenciales recursos en alimentación y salud de la humanidad. Las macroalgas colectadas en febrero de2019 se clasificaron taxonómicamente en 6 especies: Desmarestia confervoides, Desmarestia antarctica,Himantothallus grandifolius, Palmaria decipiens, Gigartina skottsbergii y Curdiea racovitzae. Se determinóla materia orgánica que fue del 12-20%, se determinó el hierro (Absorción Atómica), polifenoles yflavonoides (métodos cuantitativos). Los resultados indican que el contenido de hierro fluctúo entre 6.72 a154mg%, los polifenoles entre 22.4 a 78.4mg% y los flavonoides del 10.09 al 21.31mg%. Concluimos queesta investigación permitió conocer las características férricas y antioxidantes de 6 especies más comunesde la ...
