| Description
| - Pomocí vysokoúčinné kapalinové chromatografie s UV a hmotnostní detekcí (elektrosprej, iontová past) byly kvantifikovány monomerní a oligomerní flavan-3-oly v 10 odrůdách ječmene a odpovídajících sladech. The Folin?Ciocalteau a vanilinová spektrofotometrická metoda byly použity pro zhodnocení celkového obsahu polyfenolů a flavan-3-olů. Antioxidační aktivita byla stanovena metodou DPPH ( 2,2-diphenyl-1-picrylhydrazyl) a FRAP. Katechin byl hlavním monomerickým and prodelphinidin B3 byl hlavním dimerickým flavan-3-olem. Mimo to, prodelphinidin B3 byl hlavní látkou s nejsilnější antioxidační kapacitou v ječmeni a sladu. (cs)
- The pattern of the monomeric and oligomeric flavan-3-ols for 10 barley varieties and the corresponding malts were identified and quantified using high-performance liquid chromatography?ultraviolet detection?electrospray ion trap mass spectrometry. The Folin?Ciocalteau and the vanillin spectrophotometric assays were used for the assessment of the total polyphenol and total flavan-3-ol content, respectively, and the antioxidant activity was determined as the 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and the ferricyanide reducing power. Catechin and prodelphinidin B3 were respectively the major monomeric and dimeric flavan-3-ols. Moreover, prodelphinidin B3 was shown to be the main contributor for the radical scavenging activity both for barley and malt.
