Advancing quantification methods for polyphenols in brown seaweeds—applying a selective qNMR method compared with the TPC assay
Wekre, Marie Emilie; Brunvoll, Sondre Hellesen; Jordheim, Monica (Journal article; Peer reviewed, 2022)Introduction Brown seaweeds are a sustainable biomass with a potential for various industrial applications. Polyphenols are an important contributor to this potential. Objective The aim was total quantification of ... -
Analysis of Polyphenols from Laminaria hyperborea for application as Life Science ingredients
Wekre, Marie Emilie (Doctoral thesis, 2023-09-01)Makroalger, også kjent som tang og tare, er anerkjent som en verdifull kilde til bioaktive forbindelser. Av disse har polyfenoler fått særlig oppmerksomhet. Polyfenoler har blitt assosiert med en rekke helsefordeler, og ... -
Characterization of high value products in the side-stream of Laminaria hyperborea alginate production - Targeting the phenolic content
Wekre, Marie Emilie; Holmelid, Bjarte; Underhaug, Jarl; Pedersen, Bjørn; Kopplin, Georg; Jordheim, Monica (Journal article; Peer reviewed, 2023)Sustainable production based on renewable biomass and efficient bioprocesses are important elements in the growing blue bioeconomy. The traditional Laminaria hyperborea alginate production disposes approximately 80 % of ... -
Quantification of Polyphenols in Seaweeds: A Case Study of Ulva intestinalis
Wekre, Marie Emilie; Kåsin, Karoline; Underhaug, Jarl; Holmelid, Bjarte; Jordheim, Monica (Peer reviewed; Journal article, 2019-12-03)In this case study, we explored quantitative 1H NMR (qNMR), HPLC-DAD, and the Folin-Ciocalteu assay (TPC) as methods of quantifying the total phenolic content of a green macroalga, Ulva intestinalis, after optimized ...
