"The influence of accelerated ageing test (AAT), i.e. of higher temperature and humidity, on the content and composition of phenolic compounds in the grains of five cultivars of wheat (Triticum aestivum L.) was studied in 1998 and 1999. Total polyphenols were determined spectrophotometrically by Folin-Ciocalteau\u00B4s phenolic reagent and free phenolic acids by an HPLC method in control samples and after deterioration treatment (AAT) in the Ebi, Estica, Nela, Samanta and \u0160\u00E1rka cultivars. Statistical significance of deterioration treatment, cultivar, cultivation site, and harvest year was proved. Content of total polyphenols increased during deterioration and levels of the individual free phenolic acid changed depending on their structures. Mean contents of total polyphenols varied from 600 to 960 mg.kg-1 dry matter. The increase caused by the AAT ranged between 0 - 20 %, the greatest mean increase was observed in the cultivar Nela (by 19 %). Sinapic acid (as high as 540 mg.kg-1 dry matter), 3-hydroxy-benzo" .
