Methods for the HPLC Analysis of Phenolic Compounds and Flavonoids in Beer
Original language description
A variety of high-performance liquid chromatography (HPLC) methods are available for the determination of the individual phenolic acids, polyphenols, fl avonoids and related compounds contributing to the antioxidant activity of beer. Successful separation of the individual compounds requires appropriate selection of columns, mobile phases and optimization of the operation conditions. Ultraviolet/visible, fluorimetric and electrochemical detection techniques for HPLC determination of phenolic compounds are compared with special attention to the highly sensitive and selective coulometric array detectors. Hyphenated techniques employing coupling of HPLC with mass spectrometry or with nuclear magnetic resonance are valuable tools for identifi cation and structure elucidation of phenolic and related compounds in beer, hops and malt extracts. Finally, sample pre-treatment for HPLC of natural antioxidants is addressed.
