  7. 10. 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.
