Replication Data for: Advancing Quantification methods for Polyphenols in Brown Seaweeds - applying a Selective qNMR Method compared with the TPC Assay

These data belong to the comprehensive study of polyphenols in Laminaria hyperborea, Laminaria digitata, Saccharina latissima, Ascophyllum nodosum and Fucus vesiculosus performed in relation with the publication titled: "Advancing Quantification methods for Polyphenols in Brown Seaweeds - applying a Selective qNMR Method compared with the TPC Assay". The dataset contains 22 files, describing the quantitative content of polyphenols in the brown seaweeds Laminaria hyperborea, Laminaria digitata, Saccharina latissima, Ascophyllum nodosum and Fucus vesiculosus. The quantitative content was determined by Optimized Total Phenolic Content (TPC) assay and quantitative NMR (qNMR).
