| Description
| - Šest odrůd českých chmelů bylo analyzováno na celkovou antioxidační kapacitu. Byly srovnány dvě spektrofotometrické metody - ABTS [2,2'-azinobis-(3-ethyl-benzotiazoline-6-sulphonic acid)] a FRAP (ferric reducing antioxidant power). Korelace celkové antioxioxidační kapacity výluhů mezi oběma metodami byla velmi vysoká (0,97). Byla take změřena celková antioxidační kapacita oběmi metodami u 27 čistých látek. Korelace mezi oběmi metodami na čistých látkách byla značná (0,79). Tyto výsledky ukazují, že ačkoli obě metody mohou být použity pro stanovení celkové antioxidační kapacity v chmelech, je mezi nimi určitý rozdíl. (cs)
- Six cultivars of Czech hop were analysed for total antioxidant capacity (TAC). Two spectrophotometric methods were compared, the ABTS [2,2'-azinobis-(3-ethyl-benzotiazoline-6-sulphonic acid)] method and the FRAP (ferric reducing antioxidant power) method. The correlation of TAC measured in six hop extracts by these two methods was highly significant (r = 0.97). TAC in 27 pure antioxidant substances was measured by both methods and similar TAC values for most substances were obtained. A significant linear correlation (r = 0.79) between data obtained with the two methods was found. These results showed that both, the ABTS and the FRAP methods can be used for convenient monitoring of TAC in hops and that different antioxidants have varying reactivity in the two methods.
