Evaluation of bitter acids and polyphenols content in Czech hops harvest in 2013 ? Part II: The content of polyphenols
Original language description
The contents of polyphenolic compounds and the antioxidative properties of the important Czech hop varieties Saaz, Sladek, Premiant and Agnus were evaluated in selected samples (24, 12, 12 and 4). The hops were extracted with a water/acetone solution, and then analyzed. The results were compared with those from hops harvested in 2011 and 2012. The content of total polyphenols (TP), which are important in terms of the Protected Geographical Indication (PGI) as well as the contents of anthocyanogens and flavonoids are dependent on the variety. The highest content was found in the Saaz variety and the lowest in the Sladek variety.The only significant difference resulted between the Saaz variety and the other varieties. The antiradical activity of the hopsvarieties Saaz, Premiant and Agnus harvested 2013 was about 15 % rel. lower than in 2012. The antiradical activity of the Sladek variety was even 25% rel. lower. The highest content of the dominantly present prenylflavonoid xanthohumol (
