In recent years, an interest in the health-promoting activities of derivatives of hop constituents has grown. Pharmaceutically important substances in hop are primarily prenylated flavonoids, in the context with their proven biological effects. A reliable analytical method using HPLC-PDA for determination of all prenylated flavonoids (xanthohumol, isoxanthohumol, 8-prenylnaringenin) in hop materials was developed.
