    Sammanfattning : Biologiska processer hos olika organismer påverkas av ultraviolett-B-strålning (UV-B). Kunskapen om förändringar i UV-B-flödet som nått planetens yta under det geologiska tidsspann sedan flercelligt liv uppstod är dock begränsad. LÄS MER

  3. 2. Phenolic compounds in Fagopyrum sp. grains (buckwheat) : profile, bioactivity and effect of processing

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Agnes Wahlsten; [2019]
    Nyckelord :Buckwheat; Fagopyrum esculentum; Fagopyrum tartari- cum; rutin; quercetin; total phenolic content; gluten-free; functional foods; antioxidants;

    Sammanfattning : This study aimed to investigate the health benefits related to chemical com-pounds found in buckwheat cultivars. Factors influencing the presence of bioactive compounds with assumed health effects were examined. Two spe-cies of buckwheat, Fagopyrum esculentum (common buckwheat) and Fag-opyrum Tartaricum (tartary buckwheat) were evaluated. LÄS MER

  4. 3. Development and Validation of an Analytical Method for Phenolic Acid Extraction from Cereals and Quantification using HPLC-UV

    Master-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Laura Amann; [2018]
    Nyckelord :Phenolic acids; cereals; extraction; HPLC-UV analysis;

    Sammanfattning : Cereals are rich in phenolic acids, a group of secondary plant metabolites that are associated with reduced risk of chronic diseases. The objective was to develop and internally validate a method for extraction and quantification of phenolic acids in cereals using HPLC-UV and to apply this method for quantification of the content of phenolic acids in several species of Swedish cereals.
