Varietal specificity of polyphenols, free phenolics and antioxidant potential in hops
Original language description
Many studies have confirmed hops (Humulus lupulus L.) as the source of number physiologically active polyphenols, important for both brewing and potentially pharmaceutical purposes. The three-year screening of polyphenols and 23 free phenolics profile (HPLC/coulometric detection) showed a significant association of polyphenols and free phenolics with DPPH antioxidant potential and the genetically determined specificity of free phenolics composition in hops. Varieties of American origin have a different profile compared to European varieties. For the first time, free phenolics hydroxycoumarins were detected in hops. The DPPH strongly correlated with total polyphenols and flavanoids (n = 95, r = 0.92, 0.93 respectively) and correlated negatively with alpha acids (n = 95, r = -0.73). The polyphenols and the DPPH decrease with increasing alpha acid both among varieties and within one variety. These findings can serve as a useful tool for hop selection in brewing or pharmaceutical production.
