Název v původním jazyce

Some phenolic copmounds in Czech hops and beer

Popis výsledku v původním jazyce

The HPLC method coupled with eight-channel coulometric detector (CoulArray) was used for determination of polyphenolic compounds in Pilsner beer and hops cultivated in the Czech Republic. Some important flavonoids and isoflavonoids as well as some phenolic acids were analysed. CoulArray detector is characterized by high sensitivity and enables determination in very low concentration. Calibration ranged from 0,001 mg/L to 1 mg/L of each analytes without any clean?up procedure before analysis. The two HPLC gradients with different content of acetonitrile as an organic modifier were used to separation of compounds with different polarity. Specific oxidative potencial of each phenolic compound enables higher degree of selectivity of these chromatographic methods. The typical representative compounds from wide spectrum of phenolics were chosen for establishing of composition of Czech hops and beer of Pilsner type.
